This product is Absolute frustrating, I have bought one when they first come out about 2 years ago, it failed to perform on the first day, can't track speed, missing heaps of shots or even hard to turn on with that stupid little button. And that is the only button to use on this unit. I had a replacement unit from the agent with a Parabolic adapter, then it failed again, it started tracking every gun's shots on the range and I had to turn it off to stop it from collecting other peoples speed. But then the button failed and it could not be turn on again. Even when it was working well, it misses at least 2 shots out of 5, I had all kinds of rifles tested and tried all kinds of mounting and alignment methods. Most of them work okay if your can turn the unit on with that stupid small button but all of them miss shots occasionally. I have wasted so much time and ammo and had a lot of frustration. I'm in contact with the seller to get my money back, I have lost my confidence with this product. Don't buy it because there is a KZbin review on a new product.

How well does this work on guns with alot of recoil like a 300 win mag? I'm asking because the recoil would cause the muzzle to flip along with the Bullet Seeker, therefore moving the radar away from the bullets path.

Is the device parallel to the barrel or at an angle? It looks like it's at an angle

Did you notice any difference with the parabolic cone to help pick up suppressed shots? I’ve read that without it it can be finicky shooting suppressed without the parabolic cone.

Absolutely, this is worst case scenario. Cone should be used: It is very fast and small 223 bullet. To make it even worse, M193 -type bullet has cup-shaped base -> very poor radar cross section reflection. Also suppressor "shadows" bullet in beginning of its flight, where reflection would be strongest.
