This thread got me wondering how many holes I could get out of a battery. So I drilled one hole and stayed put for 3 1/2 hours. (Long story of Helix sonar fail, I wanna get a lithium!)
Then I tested my rig after leaving it lay on the ice the whole time. She drilled 88 more holes and stopped halfway through the 89th. I was more than happy with that. Was starting to think I would quit if I hit 100!
Makita hammer drill, 5aH battery and 6” Nils in 10” of ice. Very good outfit.
