49 1 SOUNDER MODU

OR Ul 001

Northstar's 491 Sounder.

All the information you need, all the time.

This unit offers you the same easy to use functionality and screen clarity for under-the-water information that you would expect from Northstar's unmatched chartplotter, GPS and radar. The 491 is loaded with enhanced target discrimination results. This gives you precise distinction between bait fish and larger fish.

Northstar's SoundTrac™ gives you the ability to go to a target and rename the place to save it permanently in the fish's history and easily navigate to it. The Northstar 491 is feature rich: 50/200kHz. 600/1000W. Bottom Lock. A Scope. White Line. Alarms for depth, fish, and temperature. Northstar matched transducers. Each feature can be tuned to fit your needs. Or, simply leave the 491 in auto mode and start fishing.

THE SERIOUS ANGLER'S SOUNDER

Simply press the 6100i "clear" key (CLR) to hide all menus and increase the information display area on screen.

There are four zoom modes, bottom zoom, bottom lock, bottom lock center and marker zoom. "Bottom zoom" zooms in on the sea-bed. "Bottom Lock Zoom" flattens out the bottom and shows echoes just above it. Bottom Lock Center does the same as Bottom Lock, but the sea-bed is in the middle of the zoom display (allowing you to see below the sea-bed). Marker zoom allows you to move the marker on the normal view mode, and the zoom display follows the

depth of the marker. You also can select the zoom level (as with all zoom modes).

Dual Frequency: Display 50 kHz or 200 kHz individually in full screen mode or together on the split screen.

Basic navigation data is displayed at the bottom of each screen. The alarm screen allows you to set custom fish, temperature and depth alarms to help you find specific fish.

Northstar's graphic user interface makes changing sounder settings quick and easy.
