Humminbird Helix 8 CHIRP Mega G3N Review

Humminbird Helix 8 CHIRP Mega SI

The new 2019 Humminbird lineup includes the Helix 8 CHIRP Mega third-generation fish finder. With upgraded technology, the device means that anglers have a much better likelihood of locating and catching the fish they are after. Humminbird offers the new Helix 8 with CHIRP alone or equipped with down imaging, side imaging or a combination of the two sonar systems. The new Humminbirds are also designed to power up quicker. The addition of the view button enables you to switch between a variety of full screens or split screens easily.

Mega Imaging

The Mega imaging sonar provides even more clarity than ever before. See photograph-quality images of what lies up to 125 feet beneath your vessel on the eight-inch, 800 x 480 color screen. With Mega sonar, you get up to three times the sharpness compared to traditional sonar. Using traditional 455 kHz sonar, you can often make out the structures that are below the water’s surface. However, the images are commonly blurred or fuzzy. But, with Mega technology, the details of structures beneath the water stand out better and are more clearly defined. In Mega imaging mode, you also have the option of emitting a signal at the 455 kHz, the 800 kHz or the 1200 kHz range. Zoom in or zoom out for the magnification you desire without distorting the image.

Dual Spectrum CHIRP

The dual spectrum CHIRP technology gives anglers the option of choosing the start and end frequencies. Humminbird’s CHIRP scans downward in a cone shape. Humminbird’s technology is also designed to emit more pulses faster, which equates to more detailed information and enhanced target differentiation. You have the option of selecting between using the full mode at 28 to 75 kHz or the narrow mode at 75 to 155 kHz for the greatest amount of detail. Use the wide mode at 130 to 250 kHz for covering a greater area.

SwitchFire Sonar

The technology enables you to view the depths beneath the water in two different modes. The Max mode displays the smallest of details. On the other hand, the Clear mode captures larger targets in greater clarity. Add or remove particular details and background noise as the fish finder has 20 levels of sensitivity. The sonar also clearly displays the water temperature, the bottom depth and the speed of your vessel on each displayed image. With another push of a button, watch the a
