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.. I can always find my way home.THIS GPS IS GREAT!!!
Summary: After reading reviews and descriptions, I was prepared for the graphics to be not much better than my old 498 unit. I was pleasantly surprised to find the graphics are clearly better than the old 498, even without the add-on detailed map purchase. It is annoying that Garmin decided that they needed to modify the base/clamp that holds it in place, forcing me to replace that as well.
Summary: I've bought many GPS/fishfinders over the years. This Garmin 546s is the best one by far. I've snapper fished 8+ times since getting this unit. It is very accurate and detailed where it shows the artificial reefs on the bottom. One reef was a old Army tank that was sunken and I could clearly see the gun that was still on it. Awesome unit.
