  • Compatible with new Humminbird® 700 HD, 800, 900 and 1100 Series™ models, plus Ethernet-equipped legacy models.**


Digital Signal Processing


Digital Signal Processing (DSP) is mathematical data manipulation technology. Sonar products produced by Humminbird® use transmitters and receivers that produce actual analog sound pulses and bounce them off objects, such as suspended fish and the bottom, and these analog signals must be converted to a digital format using an Analog-to-Digital converter in order to be understood by the sonar processor.

That’s when the real magic of DSP technology can be used. DSP utilizes advanced computer algorithms to manipulate the (now) digital data to filter, reduce noise, finely tune and enhance sensitivity of sonar data which equals a clearer screen, greater target separation, and more productive fish finding.

Trifuel Cartography


No one understands your mapping needs better than you. With groundbreaking TriFuel™ Cartography, the Humminbird ION and ONIX Series deliver exclusive access to Navionics®, C-MAP® by Jeppesen® and Humminbird charts. World-base maps from all three chartmakers are built into your ION or ONIX unit. For richer, detail and advanced features, select the chart SD card for your region. By giving you the option to choose the map that best meets your fishing and navigation situation, we’re taking chartplotting to uncharted territory.

Xtreme Depth


Reach a new low. Xtreme Depth™ finds fish and habitat other sounders can’t touch, thanks to a low-frequency, 50 kHz beam that goes deep and wide with a maximum range of 914.4 meters. Meanwhile, the precise, 200 kHz beam delivers high-accuracy returns of baitfish, gamefish and the bottom profile. View the beams separately or side-by-side for a complete picture.
