Humminbird Helix 12 >SI Combo features a brilliant 12.1" color display with backlight, complete with Side Imaging, Down Imaging, DualBeam PLUS Sonar, 360 Imaging, Precision Internal GPS Chartplotting and Ethernet networking capabilities.
Humminbird Helix12 >SI Combo is easy to use, dependable under any circumstances and unbelievably clear, bright and fast. No matter how high or low the sun, you can see the screen clearly, brightly, without glare, from any angle.
The Helix 12 CHIRP uses long transmit pulses that sweep across bandwidths of frequencies that are then processed using advanced Digital Signal Processing (DSP) to result in high Resolution Sonar with increased Target Separation and reduced Noise. Enhanced Target Separation allows anglers to clearly identify game Fish and baitfish, while reduced Noise offers clear, sharp Sonar images. The pulses used by the Helix 12 CHIRP Sonar, along with the advanced DSP, allow it to obtain deeper depths while maintaining optimal Resolution.
Not all forms of CHIRP are created equal. While some CHIRP products only allow the angler to utilise a pre-defined Frequency bandwidth, the Helix 12 CHIRP not only does this but also allows the user to select multiple bandwidth settings to fully customise the Sonar to their unique preferences. The Humminbird Transducer included will CHIRP between 75-95kHz and 185-215kHz.
Its 360 Imaging allows you to isolate your sweep, see 5 preset views or see all around you. The widescreen format also lets you view two screens at once, making it an ideal choice for anglers who want to compare Sonar returns. Split-screen views of Down Imaging and SwitchFire Sonar make for an unstoppable fishfinding combination.
