Product Specifications

Forget a big-screen at'll want this big-screen on your boat. The 535 has the high-resolution performance you want, with 320 vertical pixels by 320 horizontal pixels (102,400 total pixels!) and Humminbird clear edge grayscale technology. You'll see details of fish, the bottom and structure - everything an angler needs - in complete clarity. The display's contrast enhancement also makes it easy to view even in tough ambient light conditions. It's even backlit for night fishing! The single beam sonar, optimized for the best picture of the bottom and structure, is so sensitive you can track a small jig to more than 40 feet. The 250 watts (RMS) of power (2,000 watts, PTP), gives you better overall performance, and helps spot fish under cover and below the thermocline. Zero-in instantly on bottom detail to pick fish from structure with One-Touch zoom; and use X-Press menus for fast access to the most important screens. 535 Portable comes with Rugged Carry Case, Suction Cup Transducer, 2 6v Lantern Battery Operation.
