Rockwells sweet little H3 Rock Drill. The whole bolt kit is just under 7lbs including a extra battery. Pretty hard to beat, one battery will sink 10 3/8 by 3 1/2 in deep holes in sandstone. Many people I have talked to have rock pecker kits which out weigh this powered kit.
This will be part of our new Canyon Rescue Packs here on Sedona Fire's Technical Rescue Team.
