I have an Optishot 1. Total setup with a used Optishot, aftermarket mat, hitting platform, and net screen was under $400.
My results have been very consistent. They claim a few degrees of accuracy for club path and face angle and after 10,000 shots I am only more convinced the readings are accurate.
Club path is only given in 4 degree increments, which is about the most subtle amount I can control. Before the Optishot I was massively out to in. Now I can swing at +8 +4 +0 by feel. Without simulator readings this would have been very difficult to develop on my own.
Face angle is also correct to a few degrees, I would guess about 1-2.
Face impact measures heel -center -toe. I have confirmed these many times with paint on the tee. They are correct for me.
Swing speed is correct, I can verify just by sound but any radar tests I have seen show the correct speed.
Tempo is just a simple timer from backswing to impact, this cannot give misreads.
I think Optishot can be very helpful for those looking to shoot 80's consistently. It will teach you to control club path and face, and the resulting face to path angle that creates shot shape. For a lot of players this is what golf is. The accuracy will probably not be enough for better golfers, where 1-2 degrees really counts. Or those who have good control of path and face as it cannot measure angle of attack, lie, spin, etc.
To get accurate readings I taped my driver completely black, and filled the sole depressions with some light foam so that the surface presents flat. Next I passed this blacked out club over the sensors on test mode. The club would not trip any of the sensors. Next, I applied white tape to the sole, I had to experiment with the width and placement to get impact readings correct. With the tape all the sensors light right up when I flick the club over.
I swing at night without any sunlight or external lights present. It works off of infrared so any light with that bandwidth can cause interference.
