I'm in the market for the same thing pfeff been looking at 2 different ones lawrance hook 7 and the humminbird 7 both high quality big screens large depths and GPS.. now the catch if u are new to the GPS sonars or even the bigger ones go with the bird easier to run so I have been told. The lawrance units are very complex and was told one wrong setting and it won't work right witch will just make your hole day a **** off trying to set it. I'll be looking at a bird for sure
