I have a Lowrance Eagle 320 w/ GPS and use it basically the same way Polebender uses his.
My buddy on the other hand has a Lowrance LCX 38C HD and we usually fish out of his boat so trying to look at mine after being used to seeing his is pretty sad. That one that he's got is amazing screen size and definition.
But at the same time I'm still happy with mine since it is the one he had originally on his boat and when he upgraded he gave me his old one. :D
Life should NOT be a journey to the grave arriving safely in an attractive and well preserved body, rather to skid in sideways, body used up and totally worn out screaming 'WOO~HOO what a ride!'
