debounce is settings on electro guns which are used to analyse the difference between a definate trigger pull and bounce. on the eblade, you set the times the trigger has to be pulled for and also the times it has to be released for, anything less than these specific times (ie bounce) is ignored and as such the gun should not bounce.
(sorry about the crap explaination, but thats my understanding of it, im sure someone will correct me if im wrong)
