Found it pretty solid for a $600 LM. Used it indoors and out. Outside was definitely better as it can watch the ball flight longer, it was acceptably close to a Trackman and Flightscope X3 that I was on outside given the price difference with those. I have decent swing speed (over 110) and inside it did well up to driver, but driver was questionable. I was hitting into a net in my garage and never bothered to really dial in the set up to improve the driver readings (there's a ton of threads online on what you're supposed to do). Even then, still super fun to use with E6 (there's 5 free courses) and the Garmin app inside and the ranges worked well too. For the price I was happy, but ended up wanting the additional accuracy and data on the GC3.
Basically new Garmin R10 launch monitor. Bought at the beginning of summer to see whether I liked using a LM and looking at the data. I do… so just bought a GC3. Everything that came with it is included, works perfect, no issues. $425/obo, buyer pays shipping and PayPal fees. PM with questions!
