Re: Which Garmin to buy?
The first Garmin GPS I owned was a 3+. It lasted about 10 years and was very accurate. When it died I replaced it with a Garmin Oregon 450. I have SD card maps for Canada, Alaska, North America Topo and Roads, South East Marine Charts, and North Carolina Lakes and Rivers. The. Unit with all maps and settings it is about 100-400 yards out of sink with the actual location.
Got little support help from Garmin. My cell phone GPS is more accurate.
