The Lowrance GlobalMap 4800M displays towns, roads, airports, and thousands of other destinations.

As with the best GPS navigators, the device is highly accurate, with precision 12 parallel channel GPS and WAAS mapping that gets you to within a few meters of your destination, whether you're on a Great Lakes fishing expedition or a cross-country road trip. Each trip is completely customizable, with the ability to chart paths, waypoints, trails, and more. You can also easily recalculate your trip should you get distracted and lose your way. And thanks to the MMC/SD card slot--which is protected by a waterproof door--the device can save and retrace up to 100 of your favorite plot trails, with up to 10,000 points in each path.

Users can also perform more advanced GPS functions on the GlobalMap 4800M, including determining the distance between two separate locations, creating and editing brand-new routes, and navigating trails and paths backwards. To give users a good mapping foundation, Lowrance included a built-in continental U.S. and Hawaii background map that's enhanced to take advantage of the high-resolution display. The detailed map offers such marine features as more than 60,000 nav aids and 10,000 wrecks/obstructions in coastal and Great Lakes areas, along with landlocked extras like interstate exit services in addition to standard major streets and highways. The GlobalMap is also compatible with Lowrance's optional MapCreate 6 custom mapping software (required to enjoy a full set of searchable land features, including landmarks, streets, addresses, and points of interest) and a host of plug-and-play choices, like FreedomMaps, Fishing Hot Spots Elite, LakeMaster Pro Maps, NauticPath USA, and Navionics electronic charts. Each item loads through the MMC/SD memory card slot, which supports up to 256 MB of mapping memory on each card.

The maps are easier to read than ever thanks to the vivid backlit display, which sports a crisp 480 x 480 pixel resolution, wide viewing angles, and multiple lighting levels. Users can even read the screen on bright, sunny days--a serious advantage for midday boat trips. Meanwhile, users with a zest for detail will appreciate the 38 map zoom ranges (from 0.02 to 4,000 miles) and the 42 graphic icons used to mark special spots. Additional features include 1,000 waypoints and 1,000 event markers, 10 user-selectable background languages, and a built-in backup memory for storing your GPS data and settings. Technology-minded users can make the GlobalMap even more versatile by adding such navigational extras as NMEA2000 sensors, fuel-monitoring equipment, or a radar dome.

The sealed, waterproof GlobalMap 4800M, which is suitable for saltwater use, measures 6.9 by 5.4 by 3.4 inches (W by H by D) and is typically powered by a 12-volt boat or vehicle battery. lt comes with a gimbal bracket for dash installation, along with all the necessary cables for battery connection and a face cover that protects the device when idle. As with all Lowrance GPS receivers, the item is backed by a one-year warranty.

Buyer's feedback: - * good GPS for price but remember.............. ...
I purchased this unit to match an existing depth finder by Lowrance so the electronics would match on the helm. However I did not expect the SD card you really need to purchase to make this GPS usefull in the marine environment to be as expensive as it was. So expect to spend and additional $150 plus depending on your area of coverage.
