Featuring a large 8.4" display with LED backlight, the ONIX8ci CT SI Combo Color Dualbeam Fishfinder from Humminbird uses advanced digital sonar processing to accurately map the lake bottom. The ONIX8ci CT SI Combo is a complete fish finding and bottom mapping combo with a head unit, gimbal mount, and a stern mount transducer. You can choose to mount the unit using the included gimbal mount, or in-dash with an optional adapter.
This unit's transducer emits up to 8000W of PTP power, so you can read bottom in depths as deep as 1,500'. Separate beams combine to provide great detail and a wide coverage area. Side imagining technology gives you a sharp view out 150' from the side of your boat.
With the ONIX8ci CT SI Combo you will always know exactly where you are going thanks to its GPS chart plotting which, features Humminbird TriFuel Cartography. TriFuel Cartography gives you access to world background maps from Navionics, C-MAP and Humminbird LakeMaster. You can create your own maps using AutoChart Live. AutoChart Live allows you to create digital, detailed maps while you are out on the water. You can also use it to enhance your existing charts, overlaying previous mappings with your newly acquired data. A GPS antenna is included in the head unit so you don't need to purchase an external antenna.
You can control your fishfinder just like your smart phone, using multi-gesture capability that lets you navigate menus and activate features with a tap, swipe, or pinch. Cross touch technology also minimizes false touches from splashing water. You can take screen shots using the included Screen Snap Shot technology, so you can study them later, when you're back at the dock. Split screen features allow you to get a detailed look at two separate sections of bottom.
This unit also features a high level of connectivity. It can connect with FUSION marine entertainment so you can listen to music or watch videos, and monitor engine data using NMEA and NMEA 2000 marine networks. Dual card slots allow you to access existing data and store your own. Using the optional Ethernet adapter you can add up to five additional devices including IP cameras, and share data with other devices. Adding the i-Pilot Link will let you control select Minn Kota trolling motors. You can also add Automatic Identification System (AIS) technology that allows you to see, and be seen, by other vessels equipped with the same technology.
