I have a folding golf bag cart that has a bucket bolted on to the foot. I can stack another bucket or two inside and keep my tackle in them. The Lowrance fit's in it. A hole drilled in the bottom for drain if stuff needs to stay dry in the next bucket up. When I get to the prime spot it folds and makes a chair to sit on flip a bucket over and a stand for the Lowrance.
I am the son of the "Enemy of Good"
My father back before the invention of all the ice shanty's took flexible flyer kids sleds and gutted the skins off 30 gallon water tanks and chopped up lawn chairs for the tops and built ours. The adage was if something is working good someone will try to make it better. I am proud to say I carry on that thought.
