This is my review after the first 2 sessions with Velociradar.
We have several known and well tested projectiles with very good BC data.
We took this to the range and as another has said, the microphone would pick up other peoples shots, but the recoil jack did work. It's not too inconvenient to use wrapped around the magazine.
We noted, next to a Garmin most of the shots were within a few feet per second WHEN IT ACTUALLY READ. Which at this stage is only about 75% of shots.
The BC data is wild and often no where near what the actual projectile BC is, which means we cannot trust the BC data at this stage.
We had several erroneous readings at say 500 feet per second.
I believe this affects the dope chart which also gives non-sensical reading.
Even with poor signal it appears to read an OK MV... most of the time.
However we bought this due to it's BC feature for projectile geometry test, and so far it has been abysmal.
I don't think this system works well at a ranges where you shoot over target boards or berms which must bounce back signals that interfere, which is unfortunately 90% of ranges world wide. We found aiming it slightly high helped this to a small degree.
It's my opinion this unit MAY work on open, flat terrain but we are yet to test that. I will update my review as more testing is complete.
As for now, if you are just interested in MV, there is a better more reliable choice out there right now, and there are 2 products which are far more reliable that tracks bullets to 300 meters, and is far more trust worthy. One particular projectile we know after 2000 rounds of testing is 0.39 G1, almost right on the money, the Caldwell reads it from between 0.119 G1 and 0.40 G1. Does it do what it says on the box? NO! I'd return it at this stage and may look into my options for doing that at this stage.
Further updates to come.
Right now you'd be better off putting your garmin 100 meters down range and shooting over it (or 200 etc) and then calculating your BC. It's a proven method now and will work better than the Caldwell in 100% of cases. Thinking of sending mine back, but wont until we do open air testing.
