With early season ice I usually don't do much hole hopping, so I know I'm going to stay in a certain area. I walk out first with the auger in hand & drill 4 - 6 test holes. I won't bring the ATV onto the ice unless there's a good solid 5 inches around me. Since my UTV weighs twice as much as my ATV, I won't bring it on the ice unless there's a good solid 9 inches. Everyone has their own comfort level, so just play it smart & be safe.
