Garmin 76S
I've had my 76S a couple of years.Great Unit. I use it for land travel also. Useful attachments are the pc cable, remote antenna, and dc/ac plugs. Used it last spring on a 400 mi trip and every navaid I needed was on the base map that comes with the unit.Garmin web site support is great. I accidentally erased all the base map waypoints and just downloaded them from the web site.Purchased the Mapsource Blue chart Americas CD and downloaded the charts I wanted for Lake Michigan. Looks exactly like the paper charts. The Bluechart cd allows you to plan your routes on the pc and then download/upload them between the pc and the 76S. Very slick. Installed two cd plugs in the cockpit and mount mine at the wheel. Also, have dc plugs in the cabin. With the remote antenna, I can monitor position in the cabin while updating progress on charts. Also, have plug/antenna in my birth so I can monitor the anchor alarm at night, check barometer etc. Trevor has great eys, the screen measures 1.75 x 2.25 inches, and I can read it OK at arms length, but not much further without squinting. Sunlight will wash the screen out. I've used it at night and then you can really see it well. Sorta like playing a Gameboy.The 76S has all kinds of features. Punch a button to capture current positions for later transfer to the paper chart. Other neat feathers include tide tables, altimeter, and barometer. I don't find route planning on it very hard, but doing routes on the PC is the way to go. The "breadcrumb”-tracking tracking feature is great -- you just tell it to reverse your track and you have an exact return route to follow home.Took me about a year to learn how to use it without getting confused by all the menus. This is one amazing piece of technology. More expensive (and easier to read) fixed units have all the same stuff, but they are not as versatile. I keep finding new ways to use it on land and on the water.Best I can tell, the 60S will be priced about $100 above current price for 76S. As a result there is bound to be further discounting of the 76S. Since the two units appear to have similar capabilities, I'd wait to see if the color screen and additional memory of the 60S is worth what you'd pay over the 76S.
