Hello all. So I bit the bullet and ordered the GC2 brand new from Foresight. My goal/intention is to use it as an in home driving range (not so much interested in sim). As such, and even though I also received the FR1 software and a few courses with my purchase, I set it up (initially) without downloading/updating anything. I literally just wanted an out-of-the-box experience; flip it open, push the power button, and go to work (happy with numbers only)... Unfortunately, there seems to be pretty significant issues. Please read on...
The problem? My distance numbers are off by 20% (give or take) on every shot, and I even question the spin numbers... I'll use my 7 iron to give you a visual: My "normal" (real life) 7 iron is in the 165-170 yard range, no roll (my divots are within 5' of where the ball ends up). On the GC2, I cannot (even if I swing for the fences), get a distance reading of over 150 yards. Most of my shots are reading right around 140 yards; FOR A 7 IRON!
I have read EVERY thread relating to the GC2 within these forums, and yes -- I've read the few that talk about potential issues perpetuating distance type problems. None of the advice (potential diagnosis') seem to apply:
Here are a few important notes with regards to what I've read from previous threads:
1) I use a CCE mat. As such, I've teed it up to ensure clean contact. No change in results noted.
2) I have ensured the unit is level with the hitting surface, and even tried to elevate the unit by as much as 1/2" above the hitting surface. Again, no change noted.
3) Yes, I've ensured that the kickstand is all the way deployed, and the unit is all the way open.
4) I have experimented with varying degrees of lighting. No change noted.
5) I've been hitting balls into my Net Return, off the CCE mat, for over 4 years now. My garage has 15' ceilings. Previous "launch monitors" (the cheap radar type) have always been relatively on par (indoor) with my outdoor swing speed and carry distances. As such, I cannot attribute this to the "indoor effect."
6) I have ensured that measurements are in yards/mph/etc...
7) I have tested with the pro V1, the pro V1x, the Bridgestone 330, and the Taylor made TPX. No changes noted.
Before I move on, here were my mizuno shaft optimizer numbers with a 6 iron (also validated by a custom fitting at Izett golf):
Head Speed 94mph | Tempo 4 | Toe down 5 | Kick Angle 7 | Release factor 9. The mizuno fitting recommended a project x 6.5 shaft, and I LOVE them...
I just documented a few swings on the GC2, swapping out balls each time... I also measured a few with a tee (top of tee about 1/8" above the turf), where I was sure contact was clean. Also; the unit might not be perfectly aligned, but I eye-balled it parallel to the hitting mat (perpendicular to the net). Here are the numbers (I'm right handed):
For perspective, these numbers are typical of my "real life" 9 iron distances (per laser range finder). I'm not the greatest golfer in the world, but I have a very clear understanding of my iron gaps. Also, on swing 1 and swing 4 I tried to "draw" the ball. The ball clearly hit the net just about center, and spun to the left (you can see this happening with the Net Return). My normal miss (in real life) is a pull, sometimes a pull hook.
To me, the launch angle and back spin seem to be way off, but I'm not an expert with GC2 numbers...
To be clear: I have not downloaded/updated any software. I literally took it (the GC2) out of the box, and went to work. Again, I'm not very interested in simulation software; I just want numbers (plan on using the ipad app almost exclusively).
My "version" (per the unit display) is 4.0.0.15; "copyright 2015."
You guys are the experts and so I'd love to hear/read your opinions. Another member is currently emailing me the 'tilt-calibration' software, but I'm a little upset that this may be necessary. The unit is literally brand new (just received it two days ago)... Do you guys think that the tilt calibration is the obvious solution, or can something else be going on? Must I hook this thing up to the internet and download drivers/software for it to work properly???
Looking forward to any/all responses; thanks!
