Both freshwater and saltwater anglers alike need gps fishfinders with maximum cartography options. JMSOnline.net has Garmin gps fishfinders with patented BlueChart® technology that comes preloaded with maps of the entire US Coast, Alaska, and Hawaii. Find fish around wrecks, know where the coastal shelves drop off to great depth, and keep track of tides—all in a single unit. Use the same fishfinder gps on freshwater lakes by adding preprogrammed data cards that show you campgrounds, underwater roadways, boat ramps, and marina locations. This data will often give you the edge in winning a tournament by showing your exact position over structure and where the closest weigh station is should you land the catch of the day at the last minute when time is most critical. For more freshwater tournament options, invest in a Lowrance gps fishfinder that not only details marine coastlines for the continental US and Hawaii, but also includes 3,000 hot fishing lakes with details of depth contours and underwater structure. And, if that’s still not enough, you can chart your next course with even greater detail by upgrading your Lowrance gps fishfinder with additional plug and play options from MapCreate ™, FreedomMaps™, Fishing Hot Spots® PRO, LakeMaster® Pro Maps; NauticPath™, and Navionics® electronic charts. 
 
Fishing over dense structure such as multiple wrecks, submerged roadways and trees, or man-made fish attractors requires the best resolution possible. With a Hummingbird LMS 520C, you can track the school with high-speed updates—perfect for fast movers like hybrids and stripers. The wide viewing angles on this gps fishfinder render highly detailed images at 480V x 480H pixel resolution equally clear in all light conditions. If the tournament runs into dusk, when human vision is at its weakest, consider the extra advantage this will offer you in making that last—and possibly winning—catch of the day before heading to the marina. The 520c fishfinder gps features a cold-cathode screen and keypad backlighting feature engineered for multiple sonar display color choices, so you can make instant adjustments if need be over irregular depths and unstable water conditions. This fishfinder offers added value through compatibility with all Lowrance gps plug and play upgrades. We have a number of other Humminbird and Garmin gps fishfinders offering even more specialized features, such as Precision 20° Single Beam sonar optimized for definition and coverage, See-Thru® technology (which separates fish from thermoclines and structure), and Depth Control Gain (DCG®) for detailed images of structure and bottom densities. On flat bottoms or deep holes, having that extra angle can spot the lunker bass hiding near the underwater shelves or just beside submerged, fallen trees. 
 
Regardless of your sport or tournament fishfinding needs, gps combos through JMSOnline.net can get you where you need to go to find the fish you need to catch. Start making space in your freezer now, and dust off the shelf for your next trophy, by choosing the perfect combo today from JMS Online.
