Delivering both traditional and DownVu coverage angles, the Garmin GT20-TM Transducer also has a built-in temperature sensor. As stated in the previous sentence this transducer operates in the 77/200 kHz frequencies for traditional use, and at 435-475 kHz and 800-840 kHz for operation in CHIRP (DownVu) mode. In traditional mode, five hundred watts of power delivers depth readings down to 1900', and 750' in DownVu operation. Both a transom and a trolling motor mount are included, and a 20' cable allows for proper placement.
