it was warmer in the cave. the water stays a constant 41 degrees even when its 90 degrees outside. i need to not get wet while in there , this time of year, my clothes will freeze within minutes, after coming outside. the crack is 11 inches at its narrowest , this i must pass through, no other way by it. i thought the helmet camera will give a new perspective, into my type of hunting, why it is so difficult to get better pictures underwater, i am going to continue using this helmet cam, in the summer when i can get back into the cave with the artifacts in it. high winter water and ice prevent me from going now.
