I just got my R10 and testing it in my garage with a net. I typically drive in the 200-220 range at the course and on Trackman sims at the local indoor places. My R10 is showing my drives max 160-170 yards. I have a Rukkey Hackk Pro net about 3 feet from my garage side wall. (there is a single window behind it if this matters for the info. I have the ball 10 feet from the net on a Rukket small Tri Turf mat until my 5x4 hitting mat arrives. I have the R10 7 feet from the ball. I am on the newest Firmware from the other day. I am using Titleist RCT balls. There is a concrete step landing about 2 feet behind the R10 if that helps identifying any type of issue or if that matters. Garage doors are closed and I have a 55" TV to the left of the hitting net. I have calibrated the R10 successfully and also raised it up on a 1" piece of wood to see if that matters with no change.
