Superior target definition and enhanced sensitivity using Raymarine s exclusive wide spectrum CHIRP sonar technology. Lots of power plus CHIRP: High-resolution CHIRP sonar imagery, best-in-class target separation and up to 2,000 watts of transmit power make the CP470 CHIRP Sonar Module and exciting offshore and coastal fishing tool for serious anglers. Using a wide spectrum of frequencies and greater sensitivity, the CP470 s advanced CHIRP transceiver can see through dense schools of baitfish, identify thermoclines, and simultaneously target desired game fish. Extreme depth ranges: Target fish, identify bait, and track the sea floor down to 10,000 ft with two adjustable CHIRP sonar channels using Raymarine s exclusive wide spectrum CHIRP sonar technology. Ten times the resolution of traditional sonar: Resolution ten times that of ordinary sonars delivers stunning detail and clarity. CP470 resolves sharper, more defined fish targets using TruZoom magnification mode, and automatically filters out unwanted noise so you never miss the action below. Recognizes new transducers: Choose transducers with low, medium or high CHIRP frequencies in a variety of beamwidths, and CP470 automatically recognizes connected transducers and adjust sonar parameters for optimized performance. Independent CHIRP channels: View and control each CHIRP channel independently and create your own combination of full or split screen sonar windows on Raymarine s LightHouse II powered multi-function displays.
