This is an interesting thread, good idea. 
To me a tester needs to be consistent, and able to record accurate data not just go out and give feedback purely on feel. A way to validate is what I'm getting at. 
I've participated in about 5 beta programs and open source projects for various technical hobbies (3d printers and drones specifically) and provided valuable testing results. Brands were e3d, voron, pixhawk, opensolo, solex, and many technical diy groups.
Myself, I have become very consistent of hitting straight shots over this past year. My biggest achievement is I used to not be able to hit a 4 iron at all, to it being my favorite layup club to the ~220yd mark. My honest handicap last year was about a 18-20, but my confident plan this year will definitely be the 12-14 mark (just went out one of the first warm days in Ohio and shot a 43 on 9. A huge improvement for me, with some small errors to correct). 
I go the the range once a week and will be playing at least one round a week until November. I also just recently got a Garmin R10 and just finished setting up a 20x30 golf net suspended by some trees to swing with the R10 at home. I'd love to use the r10's accuracy for feedback on products.
With all of that I do hope I could contribute to a testing program. I enjoy doing such (beta programs were selected upon experience, but open source projects are voluntary) as well I am fully engulfed in golf (pun intended). I especially would love to test more technology for the course. I also feel my technical background could really prove useful with feedback on that front.
Lastly I want to say thank you to mygolfspy for even giving us hackers the chance to test and give real-life feedback. Pretty neat opportunity. 
Cheers!
