TechDisc Talk, Episode 1: Unlocking Disc Golf Performance Metrics

Are you ready to take your pursuit of better disc golf to the next level? Yeah?

Keep reading!

This post provides additional information to pair with TechDisc Talk Episode #1, the 8-minute video below in which we explain how the mindblowing TechDisc platform changes your game by revolutionizing your understanding of your throws.

After working directly with dozens of clients using a TECHDISC, I don’t hesitate to recommend the product and platform to everyone, with one caveat: It isn’t like Invisalign, magically correcting your over-right (Get it? Over-right/overbite?) by being under your pillow while you sleep. The disc itself can’t help you at all, in fact. But you can’t use The Platform without it.

The TECHDISC Launch Monitor Pro measures speed, spin rate, angles, and much more!

If you’re not yet familiar, TechDisc is a hardware/software platform that includes a disc with sensors in the center of a disc that measure the forces and angles during a throw. The data is transmitted to a web app that determines the throw type and calculates six throw metrics and a simulated flight.

The Six Key Metrics: Unlocking the Secrets of Disc Flight

TechDisc tracks six crucial metrics that together with the simulated disc flight numbers mathematically describe a throw: Speed, Spin, Nose Angle, Hyzer Angle, Launch Angle, and Wobble. Understanding these metrics is essential for training and improving your disc golf game. Let’s take a closer look at each one:

Speed: Measured in MPH or KMH, speed indicates how fast the disc moves through the air. Generally, more speed equates to more distance, assuming identical throws. However, higher speed can also make a disc fly more understable.

Spin: Tracked in TechDisc as rotations-per-minute, spin helps the disc remain straighter by resisting turn and fade, potentially increasing distance. Higher spin stabilization creates a more stable flight.

Nose Angle: Also known as “Angle of Attack,” nose angle measures the back-to-front pitch of the disc relative to the oncoming air. A positive nose angle (nose-up) increases lift and drag, causing the disc to travel high and drop quickly. An ideal nose angle for flat distance throws is around -2° to -3°8.

Launch Angle: Launch angle is the angle of the disc’s flight compared to the ground. Ideal launch angles depend on the nose angle and speed of the disc. For instance, for a 60 MPH throw, an 8° to 10° launch angle combined with a -3° to -5° nose angle is optimal for distance. I’ll keep that in mind the next time I throw 60!

Hyzer Angle: Hyzer angle refers to the side-to-side angle of the disc from the thrower’s perspective. It’s the main metric that controls the right and left movement of the disc in flight. Maximum distance throws usually have a slight Anhyzer angle for most of the flight, fading to Hyzer towards the end.

Wobble: Wobble refers to the Off-Axis Torque applied to a disc during a throw. It introduces turbulence, inducing drag and creating a more chaotic, unpredictable flight. Wobble often correlates with low spin rate or low Advance Ratio. Consider how a spinning top’s wobble increases as its spin rate decreases.

The Advance Ratio

Advance Ratio is a calculated (spin times disc radius over speed) TechDisc metric that shows the relationship between spin and speed for a given throw and is a good measure of optimal spin rate. An Advance Ratio of 50% is a good target for a backhand throw, and 30% is a good target for a forehand throw. The body mechanics involved in proper backhand form create more spin than forehand throws, on average.

Utilizing TechDisc for Improvement

Understanding these metrics on a basic level is all that’s required at first. After that, TechDisc will deepen that understanding so you can ask and answer the right questions about your own game. The real power of TechDisc lies in its ability to help you translate this knowledge into tangible improvements on the course. Here’s how:

Identify areas for improvement: By analyzing your TechDisc data, you can pinpoint specific areas where your technique is lacking. For example, if you consistently have low spin rates, you can focus on drills to emphasize snap, like our Asynchronous Drill.

Experiment with different techniques: The TechDisc platform allows you to experiment with different throwing techniques and see how they affect your metrics. This can help you optimize your form for maximum distance and accuracy, and test new theories on how to throw flatter/faster/further.

Track your progress: Since the platform stores all your data, it also allows you to track your progress over time. This provides valuable feedback and motivation to keep you on track.

use both the Techdisc App and Website

The smart disc can connect via Bluetooth to the TechDisc app and an account logged into techdisc.com on a web browser, with captured data stored on the same servers. Both ways of capturing throws and accessing the data have their uses. The app offers portability and several bells and whistles, while the browser interface is device-neutral and houses the Flight Simulator.

The Flight Simulator

TechDisc offers a free Flight Simulator for anyone to use. With it, users can:

  • Create virtual disc profiles with flight numbers and weight, then simulate throws to see how they behave
  • Modify metrics (speed, spin, hyzer angle, etc.) to understand their impact on flight
  • Get concrete, actionable answers to questions like “How close am I to throwing 300 feet?” and “What changes are easiest to make or most impactful?”

As a disc golf instructor and writer, I’m probably more excited about TechDisc than most because it opens up an entirely new avenue for explaining and understanding disc flight.

Understanding disc flight, in and of itself, is half of the equation to achieving longer, straighter throws. Throwing mechanics account for the other half. This means that potentially half of your possible improvement right now can be achieved without getting any better. Only smarter!

Jack Tupp’s curated collection of disc golf news, takes, tips, and stuff for the week of April 14th, 2024

Hey there, it’s been a minute, but welcome back to FrisbeeGolf Friday!

Kristin Tattar, as usual, teed off in the final group in today’s DGPT event in Nashville. She isn’t in the lead after round 1, but that will probably change. Her events always have the feel of the fastest runner in a relay race who is behind when she is handed the baton and immediately begins steadily stalking the pack. A few moments of observation is enough to see the inevitability of it all.

I am a huge fan of Tattar because she focuses on playing disc golf at the highest level rather than the many ancillary opportunities that come with success on the course. Specifically, she is driven by the quest for lower scores rather than the need to constantly “produce content.”

Our sport has a history of top players allowing these two elements to become imbalanced after achieving a level of success, along with others who use disc golf as a vehicle for their “platform” from the get-go. Brodie Smith leaps to mind as an example of the latter, but as I wrote back in 2020 to each their own. His sidekick Ezra actually came close to winning a week or two ago, so who says you can’t have it all, at least for a little while?

How cool is it, though, to watch an elite athlete practice their craft, dedicated to squeezing every drop from the massive reservoir of potential with which they were blessed?

Check out this recent interview of Tattar to see why I think she is unlikely to fall from her current level of play anytime soon. If her competitors want to see those steely eyes on the lead card less often they will need to come up to her. Barring injury, I see the Kristin Tattar disc golf machine continuing to roll along.

I love capturing disc golf in photos. This one of my pal A. seems to resemble a ball golf swing follow-through as he arcs his back to execute a technical turnover upshot using just the right mix of extra spin and angle.

In case you missed it, my most recent instructional post explains “Arm Brain,” a term used here at School of Disc Golf. I made it up one day in a lesson as I was attempting to explain an athlete’s tendency to revert to old, flawed mechanics— and specifically what things trigger that mistake.

Most of my clients come to me using primarily their arms to throw, and we change that by focusing on improved timing, balance, and use of the largest muscles to supply most of the power. Arm Brain becomes a named adversary for us to resist and overcome by focusing on the action and effort rather than the intended result.

disc golf stuff report

I received a couple pretty exciting packages in the mail this week. First was a copy of the board game Birdie Pro! from Steve Dodge. I am lining up a good group of testers that will include disc golfers, board game junkies, and hopefully a non-disc golfer, if I can find one!

Birdie Pro! by Boda Brothers

Expect a report on the experience soon.

Two days after receiving the box from New England, another arrived from thousands of miles away in the exact opposite direction— China. A new (to the U.S. market) company called X-Com sent me a selection of their lineup to try, in various plastic blends named for planetary bodies. Mars is premium and Earth is baseline, I believe, with more blends coming. I’m encouraged by the fact that their discs are quite affordable, and available in lighter weights, perfect for developing players. This starter set is a good example.

X-Com discs: Let’s see how they fly!

I’ll share some observations in a post soon, but you can already get your hands on ’em now at Infinite Discs. The molds seem to mostly be named for constellations and planets, but the stamp on this guy caught my eye. We’ll see how he flies!

In another recent post I shared pics of the new model of Idio Syncrasy disc golf shoes I’m testing right now. Yesterday’s round featured great weather, but the ground was still swollen with rainwater and it felt like walking on full sponges in many places. My feet remained completely dry again, which is great, but what I really noticed during this round was the traction and sure-footedness on a wild array of surfaces.

Wet teepads, wet, sloped rock, wet, turf . . . you get the idea. Like the first Idios I tried, these really do feel secure for the sport of disc golf. The difference is especially noticeable compared to a pair of shoes with worn outsoles, which was the case for me. If it’s that time for you, give these a try. They’re made for disc golf!

Two pairs of Idio disc golf shoes on a saturated course for two hours, zero wet feet!

Watch for the second part of our series on getting the most out of TECHDISC coming soon. We’ll be sharing a couple client testimonials and exploring best practices using the smart disc and app with a net.

in the news

The Disc Golf Pro Tour is eagerly jumping through the necessary hoops to enable sports wagering on professional disc golf. Will this result in our stars being less accessible to the fans— or should it?

The inclusivity of disc golf is still a major selling point, in Missoula and elsewhere.

Amboy, Illinois, is finally getting a disc golf course. At Amboy!

And I’ll wrap up this edition of FrisbeeGolf Friday by saying thank you to Brooklyn O’Kafka, a 13-year old Canadian who will be promoting disc golf to her classmates along with free discs from sponsor Latitude64. Keep up the great work, Brooklyn!

Unlocking Your TECHDISC, Part 1

As a coach, I am always on the lookout for better ways — sometimes just additional ways — to help clients understand key points. Being able to reliably measure the forces applied to a thrown disc is a seismic shift in this regard.

After working directly with dozens of clients using a TECHDISC—some in-person at our facility, others remotely, using a TECHDISC they purchased—I don’t hesitate to recommend the product and platform to everyone. I’ve witnessed the impact it can have within a single 2-hour introductory lesson. Remote coaching (video conferencing, chatting) instantly becomes 50 percent more effective when the client has a TECHDISC in their hands that produces data on my screen.

I have a disclaimer, though. My perspective is undoubtedly skewed. My experience with TECHDISC has thus far been through personal use, and as an instructor. As a user, I began with an advanced understanding of disc characteristics and throwing mechanics, and my clients, through working with me, have access to that “interpretative” knowledge as well. For others, unlocking the true benefits of TECHDISC might not be so automatic.

It reminds me of when I discovered creative apps like Photoshop or Garageband. In both cases I was excited at the potential to create art and music, only to discover that there would still be tons to learn about the products and the media upon which they were designed. I was daunted by the learning curve required just to get started.

Using a TECHDISC is simple. Download the app, connect via Bluetooth, throw the disc, and flight numbers appear. Using a TECHDISC to get better at disc golf, however, is not so different than an artist or musician learning to use the aforementioned apps from scratch.

This is the first of what will likely be a series of posts intended to help fellow disc golfers unlock TECHDISC. The plan, to avoid bogging down with lengthy technical discussions, is to touch on several different areas in each post, including:

  • Exploring the platform— Capturing and viewing throw data is only the tip of the iceberg
  • Understanding the numbers as interlocking components of disc flight
  • Applying that understanding to the confident creation of the ideal combination of disc, throw type, and throw-type details (the stuff measured by TECHDISC) —something that must be done in less than 30 seconds, again and again.
  • Going from “knowing what to do” to “How to do it” to “I’m doing it!”

If readers ask specific questions in the comments or by contacting me directly, I’ll do my best to address them in the next post.

Before starting, I want to draw special attention to the last bullet on that list. If you buy a TECHDISC, read the rest of this post and the others in the series, feel you’ve gotten a good handle on the first two bullet points, but still struggle with the 4th and maybe also the 3rd and therefore see no measurable difference on the course . . . don’t be discouraged.

Read our reviews on the site or Google Maps and you’ll see a repeating theme beyond the generous compliments; people of widely varying skill levels and experience who only needed to work 1-on-1 with an expert who can tailor the lesson to their needs. If that is the last piece of the puzzle left to be able to throw to your potential, why not? Think about it, and in the meantime let’s begin our deep dive into TECHDISC.

when to use The App and when to use techdisc.com

A disc golf disc with a TD (short for TECHDISC) puck attached to it can interact with the TD platform in two different ways; by connecting it via Bluetooth to techdisc.com on a web browser, or to the iOS or Android apps. Don’t think of it as either/or; both methods have their uses.

Connecting your TECHDISC through a browser has the benefit of universality. Pretty much anything that can get an internet connection, has Bluetooth, and isn’t ancient can connect to your TECHDISC, if needed. But that’s not where the web interface shines, just a nice backup plan in case the app isn’t available.

One person throws the TECHDISC while the other holds a smartphone with the app open.

Logging in to your account at techdisc.com is where the research takes place, compared to the app and disc, which are used to collect specimens (throw data) out in the field. Whereas the app easily connects to the disc and clearly displays basic information (along with another killer feature), the ability to dig deeper, experiment, and search for patterns exists only on the web platform.

Digging Deeper

View the list of your throws at techdisc.com, then click on one of them. You’ll see one important stat (Advanced Ratio) that doesn’t appear on the app display. This number is a calculation of spin rate and speed, and a good indicator if you are achieving enough spin for your armspeed and disc choices. You’ll also see 3D mapping based on their computer model’s projection of the throw’s flight path. (Since there are numerous external factors their model can’t take into account, don’t get too hung up on what it looks like.)

Experiment

Regardless of whether you think the 3D graphic looked like your real throw or not, clicking on it opens the secret passageway to a virtual laboratory where you can play the What-If game two different ways: Change around the flight numbers of the disc to see how the flight of your disc changes when you use a slower, lighter, or less stable disc, for instance.

Change the actual measured Throw Details of the throw being displayed to see the various ways—and what would be required, effort-wise—to get the disc to move in the direction you desire. If a throw with your current driver’s flight numbers dumps to the left, up the spin rate until it flattens out for longer, or lower the launch angle, or both.

Searching for Patterns

The longer you work with TECHDISC, the more useful the collected data becomes. This is especially true if you proactively use the platform’s ability to add tags and a note to each throw. TECHDISC automatically assigns backhand/forehand and hyzer/flat/anhyzer designations, but you can add more info. For instance, #afteraround to see how fatigue affects your form, or #cold, or #windy, or various specific discs.

More data points + more throws over time = more potential revelations about how score better through improved insights.

The App

The iOS app has been out for some, but the Android version was released more recently. I mentioned one big feature of the app aside from its simple function and optimized display, and here it is: If you want to work with your TECHDISC and know the results of each throw without having to look back to a screen, you can! Simply set the app up to audibly read out the measured stats of your choice. This works great when you’re working on something specific and use the stats as instant confirmation of whether you’re on the right track.

Spin vs. Speed

I have had similar experiences lately with three of my clients who own their own TECHDISCs. In each case, I have for some time been stressing the importance of imparting enough spin on a disc to enable it to fly as intended. I’ve done my best to explain why throwing shots with more spin and less speed allows a player to gain additional precision when needed and achieve steep turnover shots that cover short distances.

They all listened. Each of them embraced the mechanical changes we made, stressing a crisp halt of the body on drives to increase snap. Somehow, though, it became clearer—and therefore more of a priority—through the use of TECHDISC.

  • Seeing the RPM (spin) number increase when you work on a mechanical change specifically intended to increase spin is for some a more concrete form of evidence than seeing the difference in flight because memories fade but numbers are forever. Or something like that.
  • As noted above, the Customizer can be used to see how increasing spin changes flight “in the lab.”
  • TECHDISC provides a calculated metric called Advanced Ratio which describes the ratio of speed to spin rate for any given throw. It is Speed divided by RPM multiplied by the circumference of the disc. For a typical throw, an optimal ADV ratio is in the mid-40s, and this provides a simple benchmark, regardless of speed or distance.

I believe that as with many things in a sport as complex as disc golf (they say it’s easy to learn and hard to master) half of learning new skills and tricks is gaining a deep enough understanding of that element of the game. As I explain in Three Paths to Better Disc Golf (and touch on in this blog post) there are six ways to manipulate the flight of a disc. Six knobs to adjust, if you will, to get the exact flight you want. Spin is one of those knobs.

If I have a low ceiling on a 200-foot shot and need a throw that turns over at the finish, I’m probably better throwing an understable disc with a hyzer nose angle and use extra spin to create the turn, rather than releasing with anhyzer, due to the low ceiling.

My clients seem to be grasping these concepts more clearly thanks to TECHDISC, and that has given them more motivation to work on spin-inducing drills. Whether you own one or not, you can still use the Customizer to see why spin is such a crucial component to getting the flight paths you need and the distance you crave.

Hit me up with questions and I’ll do my best to answer them, and might include some in the next TECHDISC post.

School of Disc Golf: now featuring the power of TECHDISC

Hello there, this is Jack Tupp, Owner and lead instructor at School of Disc Golf.

Part of my 2023 disc golf summer was spent familiarizing myself with an amazing piece of technology called TECHDISC. I’ve already used it with several clients and have now fully incorporated it into both types of lessons we offer; in-person and virtual.

Here is a brief summary of what TECHDISC is and what it does:

  • TECHDISC is the name of the company, as well as the company’s flagship (and only) product
  • The product, which sells for $299, is a piece of hardware; a small rubberized puck that is precisely and permanently attached to a disc at their factory. Customers can choose the disc type and weight.
  • The puck contains sensors that track the disc’s speed, spin rate, launch rate, hyzer angle, and wobble rate upon release
  • The data collected by the puck is transmitted via Bluetooth to the user’s phone, tablet, or laptop, where it is displayed numerically and graphically and also stored securely in the user’s account on TECHDISC servers
  • The software platform also enables users to label and sort throws to gain additional insights
  • So far, TECHDISC has been so popular they’ve gone through several cycles of preorders. In other words, they can’t make ’em fast enough!

I’m working on a more comprehensive review of TECHDISC to be posted soon, but after extensive use of the tool and platform over the last few months these are my impressions of how TECHDISC can be used to improve one’s disc golf game— and how we’ll be using it at School of Disc Golf moving forward.

techdisc in school of disc golf private lessons

Using TECHDISC with clients hasn’t changed what I teach in lessons, nor has it altered how I teach. At least not very much. But it has supercharged both in two ways I noticed right away.

A big part of my private lessons — especially with newer players — is explaining how to generate arm speed and spin, and how to control the direction and trajectory of the disc. In other words, how to throw further and “straighter.” Before TECHDISC, my methods produced consistent results, but quite often success is delayed, at least for a time, by the fact that adopting proper technique can feel strange.

I would explain mechanical changes and drills to a client, and together we’d assess their throws using my eyes and experience and the client’s feel. But trusting that new feel can take time. Having the quantification and scientific measurement of TECHDISC, however, is powerfully different. It provides an irrefutable level of confirmation — positive or negative — to both student and teacher. Numbers don’t lie, as they say.

Speaking of numbers, the other instant win using TECHDISC with new disc golfers involves explaining the differences between discs, flight numbers, and how to select the correct disc for each circumstance— and why that answer changes depending on a wide range of factors. TECHDISC includes a flight simulator that allows us to see how tweaking throw characteristics (and also disc characteristics) changes the flight of a disc.

The Flight Simulator lets users adjust both disc and throw characteristics, then use the 3D Throw Viewer to see how each change affects the flight of the disc.

Having a hands-on tool that lets someone change disc and throw numbers to create hyzer flip and forced flex shot lines that end up in the same place communicates important info in a much more memorable way.

using techdisc IN virtual lessons

We have developed an excellent methodology over the years to serve those who can’t make it to Santa Cruz, but as with everything else, communicating via Zoom and email and texts is a little less effective than being in the same location.

The most important thing for me in using it as a training tool is that it accurately reflects adjustments a client makes over the course of our work together. It does.

The concrete metrics of TECHDISC permit no message distortion— they are what they are. Clients know exactly where they stand in terms of speed and spin, and they gain a proper understanding of less intuitive factors like nose angle, hyzer angle, and launch angle. As an instructor, knowing the exact numbers for each throw I see on a video call makes an even bigger difference than when using it with an in-person client. I may misinterpret something I see, especially when it’s on a screen and the angle is bad, but I can trust the numbers.

I’ll go into more detail soon in a full review, but I’ve used my TECHDISC enough by now to know it is consistent from throw to throw. The most important thing for me in using it as a training tool is that it accurately reflects adjustments a client makes over the course of our work together. It does. When my clients own their own TECHDISC, they can share their throw data between sessions, and I can trust that data. It provides scientific data that confirms when they do X, the results are Y. Over time, even more patterns and trends will emerge, especially if they take full advantage of the tagging feature.

TECHDISC automatically sorts throws by type and release angle, and lets you manually label and sort in numerous other ways.

using techdisc on your own

You can of course use a TECHDISC on your own. At the very least you’ll have the coolest disc golf gadget around, one-upping the rangefinder crowd. If you expect the ability to capture and slice and dice all that data to translate into lower scores, though, that will largely depend on your ability to figure things out on your own. If you’ve had success in the past watching YouTube videos and implementing changes, and you understand technical disc golf terminology, TECHDISC should provide you with all the benefits described above.

If, however, you’re on the other end of the spectrum (many of my current clients tell me they found my website after trying and failing to watch videos and develop on their own), please remember that TECHDISC is a measurement tool combined with good database tools. It won’t tell you how to change those numbers. But, hey, that’s what me and my fellow disc golf instructors are for, right?

Contact us if you’d like to schedule a TECHDISC-powered lesson or have a question, or book online directly to reserve a date and time right now.
