If you are interested in investigating the new innovation in fish finding sonar called MEGA Imaging there are some compatibility issues you need to know about. This new technology gives you a very clear picture of what is under your boat to a depth of 200 feet or what is out to either side of your boat to a distance of 200 feet. You will be able to see underwater structures and fish that are near them. Puts a lot of precision in your fishing when you know where the fish are before you put a line in the water!
Minn Kota has integrated the capability of high resolution imaging sonar into new models of trolling motors. Models like the Terrova 112/MDI/IP, the Ulterra 80/MDI/IP or others have the MEGA Imaging built into them. That means these trolling motors have a transducer included so that you will have full support for a high resolution display. The picture of the scene under your boat is scanned from the bottom of the trolling motor shaft or from the sides of the shaft if you are looking out from the sides of your boat. All you have to do is add a compatible display to your motor and you will be set. Humminbird displays that that are compatible with Mega Imaging have the letters -1CHO at the end of their model number. This indicates that they are a display only and do not include a transducer which will be supplied by the trolling motor. Great displays to be added are the HELIX 12 CHIRP MEGA DI Fishfinder or the HELIX 10 CHIRP MEGA DI Fishfinder. At this time you can only attach one transducer to the display unit. Maybe in the future that may change. Enjoy the full capability of this new technology!
