Hey guys I'm kinda a newbie at this, but i will be buying 2 new elect. downriggers to set up a 20' starcraft aluminum boat. I'm looking at Scotty's and big Jon's. I like the Scotty's 1116 , but they look bigger and heavier?? I am mounting these on Bert's tracks. The big jon captain packs look more compact. But the captain packs don't shut off when out of water?? Not sure?? Just looking for opinions from u guys that use these downriggers all the time. Thanks guys
