Another thought concerning depth finders which have a lot of power (or use a lot of power). I have often wondered if fish can sense a depth finder and who knows, maybe the more powerful versions are actually counterproductive? Who knows?

An often overlooked feature of these big boy units is their usefulness in tracking Bigfoot. All it takes is a slight modification of cell alignment using 16 lithium AA batteries. Of course, no one should stalk bigfoot without a complete backup set. :-?
