Please - could someone give an example of a bowhunting gadget?

Everyone rails against them but aparently nobody personally possess any gadgets. What exactly are these mysterious gadgets? Is it just new equipment? An awful lot of repliers to this thread have some interesting descriptions of very new equipment in thier sigs....If it is just unnessessary, whats up with the camo, release aides, treestands...just to skim the top.

I generally do not buy new stuff as it is overpriced in my opinion. But I will not get on a high horse about it.
