Let me start by saying I was a little hesitant to spend money on ShotTracer due to some mixed reviews in ShotTracer Store. After one range/practice green session I was really impressed with how simple ShotTracer is to use. I used a tripod with a phone mount and my iPhone XS Max to record videos, then imported them into ShotTracer when I got home. The ball flight is pretty true for the most part, and I love how you can change the color and configuration of the line, add effects, etc. Some people complained it didn’t pick up their ball flight, but I didn’t experience that issue in probably 30 or so tracked shots. Maybe they weren’t using a tripod?? The only reason I give it a 4 star rating and not 5 is because, while it does track all of my ball flights, the flight is not always accurate and sometimes have to manually adjust landing area. Also, ShotTracer tends to crash a lot when attempting to save to my camera roll. Maybe because I was using ShotTracer for an extended time period?? Either way, if you’re on the fence about purchasing ShotTracer, DO IT. As long as you use it correctly, you won’t be disappointed!
