I have both the AR-7 and the Papoose. Both are sufficiently accurate to do the job of foraging and pest removal. I like the feel of the Papoose better, but as stated before it does require a case to float.

If you were going to be taking a canoe or boat trip I'd recommend the AR-7, but if that is not part of the plan the Papoose is the way to go. The case for the Papoose also will hold a fair amount of other "stuff" (including ammo; which the AR-7, beyond it's two magazines, will not).
