Better late than never. I got The Stack System over 2 years ago. Problems with ruptured tendon and bone-on-bone knee stopped me from using it. Foot was a year to full recovery. Had the knee done in January. This weekend was first full swings in quite a while, With spring here (at least according to the calendar) I’m finally going to do the program. It’s 32 degrees with flurries tonight so I’m not sure exactly when I will start but should be soon. -
Day 29 (6 Apr 26) - Snuck a few balls with the 6i while waiting for the local school tournament golf match to start. Worked on tempo - starting with 1/2 swings working to full while working the ball slightly from side to side. -

Erik J. Barzeski (@iacas) • Instagram reel 1 likes, 0 comments - iacas on April 6, 2026: "The LM1 from @shot_scope is a $200 launch monitor with a great display and extreme portability. Since 98% of a ball's distance inside of about 150 yards is determined... The ShotScope LM1 is a $200 launch monitor that made waves last fall and at the PGA Show in January. Think of it like the PRGR or the Stack radar, but in a different form factor and with a better display. It's also got a rechargeable battery (no messing around with AA or AAA batteries), and a bigger, brighter, multi-color screen over the greyscale LCD on those units. I believe it still uses the same algorithms to "guess" at the distance given the club you've chosen, assuming a relatively moderate launch angle. I do not believe it measures your "VLA" (vertical launch angle). As we know from Dr. Sasho MacKenzie, ball speed for shots 150 yards and shorter accounts for about 98% of the distance the ball travels, assuming you didn't blade the bejeezus out of it, so the LM1 can, like other simple launch monitors, really help you dial in your distance wedges. I don't think ShotScope is honoring discount codes yet (you're free to try clicking the link and using the codes in the sidebar here at TST), and it's sold out for now anyway. But, you can sign up to be notified when it's back in stock. I'll update this thread as I continue to test the unit, but so far I really like: Ease of setup and use. The quality, brightness, and colors of the display. Battery life seems adequate. I'm not sure about five hours, but… it'll last well over a full session. The battery charges quickly and with a standard USB-C cable. I had some difficulties inside when players were hitting drivers into a net 13 or 14 feet away. Many swings reported 35 MPH, or 38, or 32. My hunch was that it was seeing the speed the screen moved, perhaps, as we tried a number of configurations. It was a solid screen, not a net, and later testing to an archery net that was 35 feet away yielded consistent and reasonable numbers every time.
