A Big Little Fishfinder.

DualBeam Plus

Get the best of both worlds, with selectable narrow and wide beams you can view individually, or melded into one display. A precision 20° beam provides high accuracy returns of fish, structure, and bottom profile. The wider 60° beam provides greater coverage for fish and bait fish. You can view the two beams separately, side by side, or blended together for the most complete picture.

Switchfire Sonar

When you hit the water, you don't limit yourself to one bait. So why limit your sonar? Exclusive Humminbird SwitchFire Sonar gives you the power to choose how returns are displayed. With two unique modes, you have complete control to adjust with the fishing conditions, making our down-looking sonar an even more valuable fishfinding tool.

Split Screen Zoom

Split Screen Zoom increases the displayed resolution to separate sonar returns that are very close together. In this view, the display is split to show a narrow slice of the full range view on the right and the zoomed view on the left. The zoom preview box on the right tracks the bottom in the full range view.

Instant Image Update

As the boat moves through the water, the sonar chart updates in real time to show the latest information on the sonar screen. A real time sonar (RTS) window shown on the right side of the display always updates at the fastest rate possible for depth conditions.

The included UniMap covers the continental U.S. coastline, inland lakes, and rivers at 30 meters per pixel resolution.

Freeze Frame/Structure Marking

Pressing any arrow on the four-way cursor control instantly stops the sonar graphic display to allow a closer inspection of submerged structure, bait fish, and underwater contours. Movable cursor feature allows you to instantly discern depth of any sonar return and mark waypoints from the sonar screen for navigation. Pressing the EXIT key will exit the freeze frame and the display will start to resume scrolling. Mark the location of fish-attracting structure, bottom transitions, or any feature anywhere on traditional sonar with the Sonar Cursor.

Selective Fish ID+

Fish ID+ uses advanced sonar processing to interpret sonar returns, and displays a Fish Symbol when very selective requirements are met. When a fish is detected, a fish icon and its depth are displayed above the return that has been classified as being a fish. Three different fish icons represent intensity of the sonar return, and provide an indicator of relative fish size.

Real Time Sonar (RTS) Window

A Real Time Sonar (RTS) Window appears on the right side of the display in the Sonar View only. The RTS Window always updates at the fastest rate possible and shows only the returns from the bottom, structure, and fish that are within the transducer beam. The RTS window can be displayed as narrow (standard), wide, or off.

TreuArch Technology

Many competitive sonar products commonly use post processing software to "enhance" the arching effect produced when suspended targets enter and leave a sonar beam. This additional processing can slow down performance and exaggerate the information displayed. Humminbird�s TrueArch Technology utilizes parallel processing of sonar data to eliminate unwanted interference and noise and reveal unaltered sonar echoes resulting in true arches of fish targets. This helps anglers more quickly discern the size and depth of fish targets.

Built-In U.S. UniMap

The included UniMap covers the continental U.S. coastline, inland lakes, and rivers at 30 meters per pixel resolution. UniMap gives you an accurate chart almost anywhere you travel in the United States.

Use the Navigation chart to plan your course, to view map information, and as a navigational aid..

When connected to the included transducer, you can use the GPSMAP 536s as a fishfinders.

Navigate the Lake

The GPSMAP 536s comes ready to go with preloaded U.S. Inland Lake map data. For areas outside the U.S., the GPSMAP 536s has a worldwide basemap with satellite images in place of more traditional maps. The GPSMAP 536s also comes standard with a high-sensitivity GPS receiver for superior satellite tracking and quicker acquisition times. In addition, the GPSMAP 536s can receive U.S. graphical weather data via optional GXM 51 satellite receiver/antenna. And with an SD card slot, it's easy to add additional maps without connecting to a computer.

Sonar Transducer Included

The GPSMAP 536s comes with a powerful dual-beam transducer that clearly illustrates depth contours, fish targets and structures whether you're fishing in freshwater or off the coast. The GPSMAP 536s are also NMEA 2000-certified for easy connectivity with sensors, instruments and future marine offerings.

Add Extras with Inland Lakes Vision

With the optional Inland Lakes Vision SD card, you can add a whole new dimension of exceptional features to your chartplotter.

• MarinerEye view and FishEye view provide you a 3-dimensional perspective of map information, both above and below the waterline.
• High-resolution satellite images to help you orient yourself in unfamiliar areas.
• Auto Guidance technology searches through all relevant charts to create a route you can actually follow--one that avoids obstacles, shallow water, buoys and other obstructions.

XM WX Weather&Radio Ready

Add Garmin's GXM 51, powered by the GPSMAP's NMEA bus, and you can deliver U.S. graphical weather data directly to your compatible Garmin chartplotter. Plus, with a subscription, you can even use the GXM 51 to enjoy over 170 channels of quality audio entertainment via XM Satellite Radio.
