I go to trackman for my swing lessons and have my own GC3. It is constantly 5-10mph less on ball speed than trackman. I could swing out of my shoes and not get the ball speed trackman is telling me. Trackman is “normalized”. I was hitting 6 iron and typically play a 190 carry on the course weather dependent. I barely can crack 180 carry on the GC3. Ball speed is less with premium balls. My 54 degree is 110-115 carry on course and is barely cracking 100 carry on gc3. I’m a +2 handicap and just use it for tuning in swing changes but it’s getting old seeing the carry/ball speed be less. Any recommendations? Both were set to sea level.

I’m just really looking at ball speed. I know spin/launch play a part in this. Driver on track is around 165 ball and on gc is maybe 155 ball. This seems low but what do I know
Is the humidity setting on your gc3 turned off?
