Knowing how far to come out of your bunker is a fundamental aspect of snap shooting and playing paintball. It takes practice and repetition to master your snap shot and being the smallest target as possible. There are a few ways to figure out if you're overexposing yourself in a bunker. You have to either get in the mirror to examine yourself, setup a video camera to capture your motions, or get someone to watch you and give you some feedback. It doesn't matter how you do it, it just has to be done if you want to ensure you're playing as small as possible.
