Lowrance® Mark-4 HDI Combo Fishfinder & GPS Chartplotter 50/200/455/800kHz Package. Innovative fishfinding technology-made affordable!
Hybrid Dual ImagingTM (HDI) combines the target separation and sonar excellence of Broadband Sounder technology with the structure and bottom contour-finding technology of DownScan ImagingTM... and the results are brilliant. Fish look like fish. Rocks look like rocks. Structures are perfectly defined. You can even track your own lure! It's all presented in high-resolution grayscale, so it's much more affordable than color units.
But HDI is only half the story. The Mark-4 HDI is also a fully-functional Chartplotter, offering a highly-accurate built-in GPS antenna and a detailed U.S. map featuring more than 3,000 lakes and rivers, and coastal contours to depths of 1,000 ft. - plus optional map chart upgrades. Combined with HDI and a beautiful full-color 4.3-inch display, it just might be the pound-for-pound best value on the water today!
The Package includes everything you need... the Mark-4 HDI unit itself, as well as a 455/800kHz DownScan Imaging Transducer that provides super-detailed water column info down to 300 ft., and 50/200kHz Transducer for coverage in deeper waters up to 2,500 ft. deep. It's all ready to rock with the kind of plug-and-play ease that has made Lowrance® a favorite among pros and weekend warriors alike!Features:
