The Garmin echoMap CHIRP 43cv is the latest in a long line of Garmin aquatic navigational aids intended to be ideal for small and even unpowered craft. Due to its small size and 5V power intake, it can easily be installed even on small fishing boats or canoes and kayaks, although in such unpowered craft an external source of power will still be required. The Garmin echoMap CHIRP 43cv comes with a complete U.S. LakeVü catalog of maps pre-installed, with the ability to update, modify and enhance them by updating via a MicroSD card, although purchasing one as a prerequisite is not necessary.
What sets the Garmin echoMap CHIRP 43cv apart from other units is its understanding that aquatic geography, unlike its terrestrial analog, is highly variable. Even somewhat calm waterways can change their banks rapidly after a severe thunderstorm, and even the most tranquil lake beds shift, flow, and swallow up new debris on a daily basis. Therefore the Garmin echoMap CHIRP 43cv is designed to update itself as you use it, based on the data you provide it with just by using it. Underwater maps created by the transducer you attach to the Garmin are saved within the unit, and the ability to accommodate up to 64GB MicroSD cards enables a very large amount of data to be stored. While it is necessary to provide your own transducer, the Garmin echoMap CHIRP 43cv is compatible with most transducers on the market, with no need to obtain specific hardware or software. Garmin also offers a package with a Garmin-branded transducer included.
