The picture-like images of Humminbird® Down Imaging™ are created with high frequency sound waves emitted in razor-thin slices. The sonar returns from these waves create an instant ''snapshot'' directly below your boat. Our exclusive software analyzes the returns to verify the position of the echoes to ensure Down Imaging only shows you structure and activity directly beneath you, and not off to one side or the other. Humminbird® 596c HD DI Sonar Fishfinder features a high-resolution 640Vx640H LCD 5'' display with Down Imaging™, Dual Beam Plus sonar that has 25º and 16º beams, 4000 PtP power output, and 350' (DI)/600' depth. Speed capable/temp included. In-dash mount: 5.4''H x 6.9''W.
Down Imaging™ Use Down Imaging to reveal cover and structure detail below your boat. 455kHz/75º @ -10db; 800kHz/45ordm; @ -10db.
SwitchFire™ Exclusive Humminbird® SwitchFire Sonar gives you the power to choose how displays are returned. Max Mode displays every return for the most complete picture while Clear Mode filters returns to display only fish and structure.
Dual Beam Plus Optimized for excellent coverage of the bottom, Single Beam features 25º and 16º beams for precision with coverage of an area equal to one third of your depth.
Rated 2 out of 5 by Ken346 Not for the trolling motor
Bought this unit for trolling motor mounting. It was a big mistake. I cannot get rid of interference and have tried everything Humminbird suggests in the FAQ section. For the front of the boat it's a real lemon. I'm putting my old Lowrance X87 back on.

Rated 5 out of 5 by family1stfishing2nd So Far Great
Appears to be a great product. Heard shallow water was a problem, but fished 1-1/2 feet to 8 feet and only had occasional periods where screen did not show clearly. DI worked in 3 & 4 foot with no problem. Was fishing shallow bay with lots of grass. Seems pretty easy to use, but really did not try adjusting. Installation was a snap.

Rated 4 out of 5 by Simple2loose Kicks Lowrance out the water
Got a lowrance unit Elite 5 with gps it a good unit but manuel doesnt explain the unit well and the unit is difficult to use too many menus i dont like spending to day pushing buttons. The hummingbird dsi 986 blows lowrance out of the water alot easier to use and understand the unit itself is put together better and as far a using if this unit show structure its there including fish... Im sure the HB customer support will also win out.

If you've never used a sonar device with a 640 vertical pixel count then you owe it to yourself to try it. It's like watching an underwater movie in HD. Simple to set up and use. Amazing quality. What more could you ask for. P.s. I to called humminbird to inquire about the discrepancy between the stated 4000 ptp wattage and the printed on the box number of 2400. The engineer at humminbird told me each 596c HD di had been tested and surpassed the 4000 ptp reading. If you click on the updated specs section on humminbirds web sight under the new di section you'll see the correct specs. Pick this up now you won't regret it

There isn't a demo on this unit. However, Humminbird does offer several videos online that show their technology and the features of the unit. I've included a link to the unit on the Humminbird website (there are 2 videos on this page), and I've also included a link to the Humminbird Video Gallery.

Electronic interference from the trolling motor. You can go to Humminbird site and try what they suggest in the FAQ section. Didn't help me. Can't use the unit at all. Waiting for an answer from Humminbird.
