I need to keep in mind that members needs go far beyond my local lakes. All the fish I catch will easily come up through a 5" hole . My 20Vmax will punch a hole amazingly fast. My son had a 8" gas thing. I almost broke my ankle in one of those holes . A young buck with a 8 or 10" gas auger can create a minefield of ankle traps in a hurry . We don't get a lot of ice I can trust in my area.
