Humminbird 899ci HD SI features the 480′ Side-Imaging technology, which Humminbird began and has mastered. It uses the XHS-9-HDSI-180-T transducer, the same one that was used by the older side-imaging models. The 1000W transducer supports 800/455/200/83 kHz frequencies, and it reaches the depth of 150’ in side imaging mode and 1500’ in broadband mode. The high frequency sonar eliminates the clutter in the water. No matter the conditions under your boat, this unit with cutting edge sonar can deliver one of the clearest displays available. The Side Imaging Sonar offers incredibly clear, virtual photographic images of structure and the bottom. This is the ultimate tool to find structure. The coverage is a massive 480 feet from side to side. Anglers will be able to scan what used to take hours in only minutes.
This unit comes with ample features most of which can be found on older models. One of those features is SwitchFire which gives anglers complete control of the 2D sonar display with two unique modes. In Max Mode, anglers can watch the sonar returns on the screen in incredible detail. They will be able to see the smallest objects underneath the water. This provides complete underwater coverage. In the Clear Mode the software will filter the sonar returns and only display structure and fish. This mode is great for reducing the undesired clutter in the water column or fishing in rough or shallow water.
The nuances of the display are easy to adjust as well. The new color pallets offer more flexibility on the water whenever dealing with bright sunlight or overcast conditions. The screen is a full 7 inches with the ability to enhance sharpness. The depth, distance and bearing are all displayed at the same time on the screen with large enough numbers to be seen from a few feet away distance. The range lines on this unit have been improved over older models. With this new approach, you can see the exact distance in range between the bottom of your boat and the nearest object. Whether a fish, a sunken boat, or debris, your display will mark the distance with lines shown in footage between you and the edge of the object.
Humminbird 899 uses the old 700-series style networking. You will need network adapters or an Ethernet switch to connect this unit to another Ethernet-ready Humminbird. The 899 is equipped with a dual SD card reader. The GPS comes preloaded with Humminbird ContourXD maps and it supports Navionics Gold and HotMaps upgrades. For clarity, ample features, and coverage up to 240 feet on each side of your boat, the Humminbird 899 HD SI offers one of the most complete options for technology savvy anglers.
