Summary: The Garmin GPSMAP 546s is leagues ahead of my old Garmin 188 GPS. The reason I did not give it 5 stars is because my old 188 had a feature that is missing from the 546s. You could select a hazard and assign a distance ring around it and if the boat went inside this range ring you would get an alarm.
Summary: I have not used the product yet, but this looks like it will a great product to use.Reading the manual and talking with other Garmin users it will a great fit for my boat.Can't wait to get this all set up to use.
Summary: I have been out of boating a while so these new things just blow me away.. I always used a compass but this GPS is great, It takes a little getting used to but once you master it WOW.I am new here in Fla so I haven't Mastered the land marks,but who needs to with this..
