The Garmin ECHOMAP 45cv with a GT20-TM Transducer is a compact combo that has lots of built-in benefits. This Garmin chartplotter is easy-to-install and even easier to use, it has a bright screen 4.3” display that is easy to read on a sunny day on the water.
It includes one transducer that features both Garmin CHIRP traditional sonar that delivers remarkable target separation and CHIRP ClearVü scanning sonar for nearly photographic images of what’s below the boat. Preloaded with Australia and New Zealand maps.
Plus, it has Quickdraw Contours mapping software to instantly create personalised fishing maps on-screen with 1’ contours as you fish. You own these maps. They are yours to keep private or share with the Quickdraw Community on Garmin Connect™.
Plus, you can share waypoints and routes with other ECHOMAP or STRIKER units. It also features a quick-release mount allowing you to quickly install and remove your device from power and mount. Transom and trolling motor mounts included.
