LI 6550 help

:confused:::hey, been using my cobra 6550 wxc for a year now with limited success. mostly for hunting and fishing. batteries take a long time to fully charge. some places they work well and others they dont. can not find anything like wattage, uhf? vhf? from cobra or on net. no mention of this model: LI 6550 WXC exclusively from canadian tire. warranty almost up so wondering if i should send back and get other, better model? $ 120.00 but bought on sale for $ 70.00. how can i find best channel for area? people do not want to spend time to find the best channel, just find one we can hear on and away we go! doesnt work for me! any help from you experts would be appreciated. thanks a lot.
