Unlock Crystal-Clear Underwater Views
Experience fishing like never before with imaging sonar that reveals details invisible to the naked eye. Whether you're scanning vast areas or pinpointing specific targets, these tools help you make smarter decisions faster.
- Enhanced Side Imaging: Peer up to 125 feet on either side of your boat with three times the detail of traditional systems. Spot submerged trees, drop-offs, and baitfish schools that hold trophy fish.
- Superior Down Imaging: Dive deep below your vessel up to 125 feet, capturing hyper-detailed images of the bottom profile. Identify rock piles, weed edges, and individual fish hovering just off the structure.
- Versatile Dual Spectrum CHIRP Sonar: Switch seamlessly between wide coverage for broad searches and narrow focus for pinpoint accuracy. Long, distinct fish arches make it easy to differentiate species and sizes.
- Customizable SwitchFire Sonar: Adjust sonar returns on the fly to cut through clutter caused by depth changes, temperature shifts, or rough water. Watch your lure drop in real time for perfect presentations.
Expand Your System Effortlessly
Build a networked fishing ecosystem that grows with your needs. High-speed Ethernet connects multiple units, while Bluetooth keeps you updated without wires.
- Ethernet-ready for adding trolling motor integration, 360-degree imaging, or radar.
- Bluetooth for software updates via app, phone notifications, and optional remote control.
- Compatible with Minn Kota i-Pilot Link, Talon anchors, Navionics, and more for a fully integrated setup.

Pro Angler Tips for Maximum Performance
Maximize your investment with these field-tested strategies:
- Mount the transom transducer parallel to the waterline at a slight downward angle for optimal signal return.
- Use wide CHIRP mode for initial scans in open water, then zoom in with MEGA imaging for structure details.
- Enable AutoChart Live during trolling to build custom contour maps—perfect for repeat visits to productive spots.
- Customize split screens to show Side Imaging alongside GPS for effortless fish-to-spot correlation.
- Pair with a heading sensor for precise waypoint navigation in windy conditions.
Anglers report finding fish-holding humps and schools missed by older units, turning average days into limits.
