I love my ShotScope V2, where I completely trust it to capture my shots accurately.
However, I think for new users it would be great if user tips are provided on their website as discussed in this forum.
Here are my tips.
1. Carry the club in opposite hand to your watch.
2. If you make a practice swing and change mind to a different club, note it so that you can edit it later. Shotscope actually is able to capture these cases pretty accurately, but sometimes does ask to confirm the club when editing. My most common issue was when I was teeing off and was trying to decide between 3W and driver based on course conditions. With that said, I usually don't make a practice swing unless I am on an awkward lie and almost never have problems.
3. If possible, don't walk across/on the green when getting to a greenside shot. Shotscope still captured my shots correctly with the correct club without waiting 30 seconds but if this bothers you just don't walk on the green before putting.
4. Do make practice strokes when putting - this is the only instance where I think a practice swing is almost necessary to capture accurate ball locations during a round. Fortunately, this is part of my routine anyway.
Hope everyone enjoys V2, as this has been a great purchase for me and I cannot see myself playing without it for now. Much better than Gamegolf and cheaper than Arccos.
