Ratings and reviews

I have no doubt that the ability to run a chronograph during our matches has increased my hit ratio. It will also ensure that you don't chase (making a correction) when a round runs slower or faster than normal. if you correct off the slow round and then run normal speed on the correction you just missed again because you were to high. I have the original version and it misses between 3 and 5 rounds per 100 the newer version misses 1 or less out of 100. Very good product

A major flaw in this application and device is that if you close the application, intentionally or by accident, when you re- open the application, it will not Connect again unless you get up, go to the device, turn it off and then back on again. Then use Connect again. All time lost in a competition and just infuriating if not. Please fix.

Its just not a good app. So confusing and clunky I'm ticked off that I spent the money on the bulletseeker to find out the app is joke. So much potential not being developed. Do you guys have something better coming soon? Really soon I hope! So...an update! Very responsive company! So good to see people truly dedicated to customer service! Rare thing now days. Anyway they reached out and we had a great conversation. Went over things and got good explanations and solved several problems I had.
