Hi everyone, I am looking to buy a gps/sounder combo for around $500/800.The sounder/gps will be used on my side console 4.5 tinny. The unit will mainly be used in inland dams and coastal rivers/estuary. I would like a unit that was extremely easy to use as I am not in the least bit " tech savvy" . I would like a colour screen of about 5" or more. I have had garmin and lowrance sounders before and I liked them. The units you buy these days often do not have a manual with them and you have to look up any operating instructions on a computer, with my limited tech skills I find this frustrating. I would appreciate any advice on the best places to purchase the gps/sounder if possible. Thanks guys in anticipation of your advice.
