In my family, we’ve always said that we had a good sense of direction. We didn’t realize it was a big deal until a couple of in-laws came into the family that do not share in this “gift.” I can’t tell you how many times we have turned around when we were going somewhere because one of the “navigationally-challenged” family members was leading the way! Then along came the ability to map out directions on the computer before you left home, which helped tremendously – you just had to know where you were going before leaving ; there was no room for improvising. Now we are fortunate to have GPS systems that can lead us the whole way.
And we don’t just use GPS for land travel. We can use the same GPS navigational tools on our boat. It can give us information on marine navigation aids, such as lights, buoys, sound signals and day beacons. Our marine GPS also provides information on water depth, tides, times for sunrise and sunset, and a fishing and hunting calendar, from its built in celestial data points. And the information on water depth can keep us out of “shallow water”, so I don’t get in” deep” trouble.
Garmin® is one of the leaders in GPS navigation systems. The GPSMAP 72H is a reliable handheld marine GPS made by Garmin®, in their marine-friendly line of navigational aids, and also works for land-based travel. Obviously, this handheld GPS device is waterproof: it floats on top of the water, and is IPX7 waterproof if it is ever submerged. The waterproof standard for IPX7 means that it is protected against immersion in water for 30 minutes at a depth of 1 meter or a little more than 3 feet.
Technical Details include:
WAAS enabled GPS receiver. WAAS What?
A WAAS enabled Global positioning system (GPS) receiver continuously tracks and uses up to 12 satellites. You’ve probably heard the term WAAS, seen it on packaging and ads for Garmin® products, and maybe even know it stands for Wide Area Augmentation System. Okay, so what the heck is it? Basically, it’s a system of satellites and ground stations that provide GPS signal corrections, giving you even better position accuracy. How much better? Try an average of up to five times better. A WAAS-capable receiver can give you a position accuracy of better than three meters 95 percent of the time. And you don’t have to purchase additional receiving equipment or pay service fees to utilize WAAS.

The term “navaids” is short for Navigation Aids, and refers to any sort of marker or point which will aid the traveler in their navigation. It is commonly used in nautical and aviation travel. Some examples of “navaids” are: lighthouses, buoys, day beacons or fog signals. These “navaids” are not attached to the vessel or craft, and are extremely important is helping to identify position, and advise of a safe course of passage, or warn of any obstructions or dangers in the path of navigation. The nautical navaids are for North and South America.
The viewable tide data available is for the U.S. only, from tide stations surrounding the east and west coast, and Gulf of Mexico.
For land travel, this GPSMap76 is also preloaded with a base map of principle cities, interstates (including exits), highways and roads. The standard map coverage has cities around the world with a population of 200,000 or more.
The GPSMap 76 series has a trip computer that will provide you with your current and average speed.
