When looking for the best GPS to use for my boat I looked at a ton of options, but a few specific products stood out. 

The Garmin GPSMap 276C

This waterproof marine GPS system doubles as a land GPS for use in your car as well. There are many benefits of this product, but I’ll only cover a few in this article.

So what makes the Garmin GPSMap 276C such a good find?

Benefits
• You’ll have color chart plotting for both sea and land use.
• The 3.8-inch LCD is designed to allow easy reading in bright sunlight plus the large digits makes viewing easier.
• The unit comes with 3000 user waypoints and an expanded list of waypoint symbols. Plus built in info on interstates, cities, coastline detail and even US tide stations.
• If you are using it in your car, you’ll be given audible turn by turn instructions once you purchase the additional 12-volt speaker cable. If you don’t like the sound of the voice you have the option to ditch it.
• The reception on this device is quite good thanks to the adjustable quad helix antenna as well as the remote antenna.

You Should Know…..
• To make the most of your GPSMap, you can use data from MapSource CD-ROMs, Recreational Lakes, and City Select for street-level maps.

The Garmin GPSMap 276C retails for about $480 and considering the great features, that’s not a bad price.

The next waterproof marine GPS system on review is the Lowrance GlobalMap 7200C GPS Receiver.

This little beauty gives you a massive 7” viewing area. You’ll probably be able to see a tadpole in murky water with this baby.

To own one of these, you’ll need to part with around $700, but I think it is worth the cost.

What I Liked
• The device is totally waterproof, which is always useful. Even the memory card slots are waterproof.
• There is an internal memory backup for important GPS information.
• If you go off course or arrive at your destination the device will announce each event with an alarm.
• There are 37 zoom ranges between 0.05 to 4,000 miles.
• Internal back-up memory for key sonar settings/crucial GPS data.
• When used with the LowranceNet system this marine GPS chart plotter can act as a video, radar or weather display. How cool is that.
• This product comes with a warranty and depending on where you shop it could be one or two years.

Hopefully this will help you save time when looking for a great GPS system for your boat.
