Yes we inspect tanks to make sure they take hits from all 4 angles. Like I said, I like the hidden receivers just would take a lot more to inspect and correct if one sensor wasn't picking up IR and if half have the system and half don't. I'm going to hear noise from both sides that something is to an advantage/disadvantage. We try to leave out user interference on the electronics. Wether it's on purpose or intentional when heavier installation is required more will have to be looked over to keep a level playing field for everyone that attends. If your a newbie that doesn't have the experience or know how to install such components to a season vet always looking to mod and upgrade, gotta get them on the same field electronically speaking. We've had hidden IR receiver tanks on the battlefield and really the biggest issue is seeing the indicator led's that you've taken a hit. If you can't see the hit led's out to 100' it's again not the same as an exposed apple that will show hits clearly.
