Setting up a sonar for ice fishing, revisited

[MisterCompletely]

[font "Comic Sans MS"][black][size 3]I've been reading the old posts on setting up a regular sonar unit for ice fishing and getting some good ideas from the likes of BLM and Tubedude etc. Some people made reference to a box of some sort that Sportsman's sold, for holding the battery etc. I'm curious whether Sportsman's still sells it, and what the general opinion of it is. Would I be better off making a custom one from an ammo box or cooler? BTW, I have 2 of those little 7 amp batteries from Sportsman's that I always use even in my boats to power my sonar units and they work great for me. I bought a little charger at Harbor Freight that I think is just 1 amp, and it looks like a miniature car battery charger, which is what it is meant for, and even has LED's to show when the batteries are fully charged. It takes about 7 hours to fully charge a battery with it. It was only $10 on sale but I think it generally sells for $17. [/size][/black][/font]
