If you go camping on really hard compact ground and you're finding it almost impossible to drive your GroundGrabba Pro, Pro I or Pro II into the ground then try pre-drilling the ground using this 1/2″ x 24″ masonry drill bit. You may need to drill the ground an inch or two at a time and keep clearing the hole if the ground is ‘that' hard. Perhaps you may also need to widen the hole too.
