360 Imaging provides a complete around-the-boat underwater image, with detail similar to Side Imaging (SI). With a single sweep, 360 Imaging covers a 300' diameter circle (70,685 sq. ft.). Choose from five beam rotation speed settings. Lower beam speeds give higher image quality but lower refresh rates; higher beam speeds have lower image quality but higher refresh rates. With five options, you can find the ideal setting for your boat speed, water conditions and need for detail. Stop in one direction and isolate your sweep area over a section of water from 10 to 360. You can lock in your beam anywhere, but the area in front of your boat is especially useful.Because your transducer has less ground to cover, youll also benefit from a faster refresh rate. Mark interesting returns with a waypoint directly on your 360 Imaging screen. The exact location will be stored in your units memory and is viewable on GPS cartography. Deploy 360 Imaging using your Humminbird unit or the control buttons found on the 360 Imaging Transducer Deployment System.The Transom Mount transducer drops below your boats hull and prop for unobstructed 360 view. Easily set deployment depth based on your prop clearance and it will be stored in the TDS memory. System operates quietly, escaping the notice of nearby fish.This optional accessory does not replace your standard Side Imaging transducer, it enhances your product. You must use standard transducer in order to have a digital depth reading.Compatible with Ethernet-ready, Side Imaging-equipped Humminbird fishfinders.
