I bought one in January from Planet Fastpitch at the Softball Coach's Convention and have had lots of problems with it. I compared the velocity readings directly to a pocket radar and there were some that were close and then others that were way off. Also, the extension reading (which is supposed to be the stride length) is way off - it read 8ft and 10ft for my 5'4" daughter and then other times it read 2' - sometimes it has read 5ft or 6ft.

I have been in touch with their tech support - they have been working on improvements/updates to the app. They are going to let me beta test the updates before it is released - I will post back when I have some feedback on whether the app updates make any difference.

I found that the readings were inconsistent when DD didn't stall between each pitch. Try to have pitcher not move for at least a second or two before throwing. That seemed to bring 10' extensions down to 5 or so consistently. Not saying it will cure all, just saying that we were much more consistent in the readings when stopping before pitch.

Yes, we tried that - brought the extension range down to 2' to 8' - still too inconsistent. The RPS and spin angle seems to be accurate - but their are still issues with the extension and speed readings.

Understood. We only received ours on Friday and have tried it only a couple sessions. Waiting to borrow a Smart Coach to compare the speed readings. Will continue to update as we track progress. thanks

I think velocity is low by at least 10 mph

I don’t have another device to compare vs. but Older DD’s boyfriend has the pocket radar smart coach and will try to get my hands on that to compare. Will report back when I have more info.
I set my pocket radar on the tripod on CON setting while throwing the DK ball... the pocket radar was consistently showing 6-7 mph higher than the DK ball...
I realized that I'm really good at throwing GYRO rise balls....

6-7 mph is a large difference. I haven't yet had the opportunity to get a comparison, hopefully soon.
