Summary: I could write a book on this, but I'll spare you. I like the 276C so much, I bought one of the few 478's because they are so similar. Yes, it's a marine chart plotter/fish finder/sounder of some sort, but I've been so very happy with it as a motorcycle gps that I now keep the 276C as a spare to my 478, simply because Garmin isn't making anything like it any more.
Show me a better navigator and I will try to discuss with you this question

Summary: I definitely like the Garmin 276. There are several reasons. It is resistant to water, which allows it to different weather and road conditions. Simple and easy to use. Has many functions and is relatively expensive. But the most important thing for me that the control buttons on the browser, which is very convenient and practical in muddy. Many modern navigators steady to water, but the touch control, which is not very convenient.
This is one of the best on the market despite its age

Summary: I knew this product by reputation and admit my good choice in ordering this particular type. It was done to target a specific goal ie: that of navigating in Africa with an associated computer. Despite not knowing how this product compares to others, I can unreservedly say it does the trick.
Summary: These units have been a favorite of motorcyclists for a lot of reasons, durable and vibration resistance, bright screen that can be seen in the brightest sun, waterproof, buttons that can be operated with gloves (many touch screens cannot, tracking function, that lets you save and review where you have been.
Summary: We use this for navigation whle fishing and boat camping in southeast Alaska. Even though it has a small screeen, it serves us very well, and we like how easy it is to take in and out of the boat, which would allow us to use it on the highways if we had any. User interface is fairly simple and installtion was a snap if you know anything about wiring diagrams and splicing wires into existing electrical or established fuse panels. Really not hard at all.
Summary: The only draw back is the battery life .If you fish in the bay system of the lower part of South Texas you half to have it hard wired to your on board battery the small rechareable just won't last half day maybe, beside that it could not be better better than good but not excellent
