My brother is an aspiring bass amateur, who will be fishing in quite a few tournaments this summer. He does not have a radio on the boat, and I would like to purchase one for him for his birthday. It would also be a good idea while he fishes, and peace of mind for me knowing he can get the weather updates. He has a beautiful Nitro Bass boat, and I know I would like to have it be Sirius compatible, but other than that I am clueless as to what I should be shopping for. Any suggestions bass-anglers and  boaters? Thanks so much!- Sunfish
