Instead of emitting a single 50 or 200 kHz pulse that bounces off objects and returns at the same frequency, CHIRP pings pass through the water at different frequencies ranging from 28 to 60 kHz, 42 to 65 kHz or 130 to 210 kHz.
In this way, regardless of the distance of the targets, pings return at different frequencies, which effectively separates even the smallest objects and provides greater image detail.
The detail produced makes it possible to watch the action around lures while distinguishing between bait balls and game fish. Images are also visible as the boat moves.
This IPX7 waterproof rated Elite-4X multifunctional marine device combines a 4.3″ super-bright LED-backlit color display, CHIRP sonar, and underwater landscape.
The Elite-4X fish finder features an easy-to-use page selector menu, TrackBack™ and recorded sonar history.
The on/off, menu, page, zoom and directional buttons on the front of the device make the unit user-friendly right out of the box. Once powered on, anglers merely choose from a series of pre-set page layouts ranging from single to triple split screen views. Look at maps while getting CHIRP or DownScan images at the same time.
The TrackBack feature scrolls stored images backwards to reassess particular structures or locations. The map feature provides information on more than 3,000 lakes and rivers in the United States along with coastal contours.
The micro SD card slot is suitable for using a variety of plug-and-play maps. Or, use a blank card to keep plotted way-points. The Insight Genesis technology allows anglers to go online and create customized maps using recorded information. Simply upload data to a no cost account, view the desired chart, make the needed adjustments and download the data to the SD card.
