Garmin 78 GPS MAP Navigator & Worldwide Chartplotter Review

Garmin GPSMAP Marine GPS Navigator & Chartplotter

If you are like me, and find you are constantly being teased because you tend to get a bit turned around with directions, you may find a GPS unit to be quite handy. Of course, today, GPS units are available on some models of cars, and can easily be installed in just about any vehicle, but what if you are just out walking around town? What if you want to plan a route while out on your boat?

For me, handheld GPS units are the best thing since sliced bread! You can tuck these little gems into a purse, pocket, or picnic basket, and you never have to worry about getting lost again. Better still, if your plans change, or you need to find some important information, these gadgets put all the details you need, right in the palm of your hand.

Garmin is a leader in GPS navigation units, and has done it once again with the Garmin GPSMAP 78 2.6″ Marine GPS Navigator & Chartplotter. This device is part of Garmin’s marine line, and offers plenty of features for both water and land use. Equipped with powerful GPS receivers, the 76CSX is one of their most popular and accurate models. The unit is lightweight (just 7.6 ounces), rugged, and water resistant to IEC 60529 IPX7 standards. Mariners will love the fact that not only does the 76CSX float, it is can also survive if it becomes submerged in up to one meter of water for as long as thirty minutes. You do not have to worry about the 76CSX dying, because you can easily get up to twenty hours of battery life when using two AA alkaline batteries.

Let’s Take A Look At Some Specs of the Garmin 78 Marine GPS:

High-Sensitivity GPS Receiver

Of course all GPS devices advertise this feature, but Garmin’s goes a bit above and beyond the call of duty. This receiver, by SiRF, can track your whereabouts in just about any type of location, including when in canyons or in a completely tree covered area.

Color Handheld Mapping – A Must Have for Outdoor and Marine Users

Gone are the days of struggling to read a map in nothing more than shades of gray. These detailed maps provide multiple colors with exceptional quality, and give you immediate access to city maps, street maps, topographical maps, and even nautical charts.

Color TFT Display That Is Actually Readable, Even in Sunlight

No more tilting and tipping to try to get your information. This unit is designed to showcase all types of trip and map data in clear, precise detail that displays in any type of lighting.

128 Mb Of Storage

Techies and non-techies alike will love this feature! The Garmin 76CSX comes complete with a microSD card for storage of optional map detail. You can even make use of the extra memory card slot to program the unit with many of Garmin’s MapSource products. These options include: U.S. Topo and Recreational Lakes with Fishing Hot Spots, City Navigator, BlueChart, and U.S. Topo 24K. You can also use the USB connection to quickly load all types of maps and charts in just minutes.

Tons Of Extra Features

The Garmin 76CSX comes preloaded with tons of great features. The America’s Autoroute Basemap offers highway data, exit information, and even tide data. There are preloaded marine databases, and turn by turn directions for driving. The device’s integrated trip computer gives you your max speed, average speed, total distance, odometer, stopped time, moving average, total trip time, and even a Man Over Board (MOB) feature.

If this was not enough, there is an option to increase the readout font size, and a dual-position display mode. Need some help deciding when to hunt or fish, or looking for sun and moon data? The built-in celestial tables will take care of that! There are audible alarms to let you know when you have reached your destination, if you have wandered off course, if you are dragging your anchor, and if you just need a wakeup call.

Perhaps the best features of the 78 Marine GPS are the navigator and chartplotter. The altimeter gives you current elevation data, your rate of ascent or descent, your maximum and minimum elevation, and your average rates for ascent and descent. The electronic compass provides you with your bearings anytime you are standing still.
