The sonar imagery feature reveals bottom hardness clearly and in vivid color, highlighting both subtle and dramatic transition areas.
Sonar imagery is generated from proprietary multibeam surveys. An angler can use it as a reference to better understand the structural characteristics and bottom composition (rocky, sandy, vegetation, roadbeds, etc.) that can inform their fishing strategies.
Included as a downloadable option with Platinum cards, it can be viewed with compatible models from many brands. Check compatibility
