The sonars in the Garmin Striker Vivid range show fish and structures in maximum detail and color. The easy-to-use devices come in several vivid color options to see fish and structure in maximum contrast and clarity. The box includes top of the class transducer with CHIRP traditional sonar and CHIRP ClearVü scanning sonar technologies (transom-mounted Garmin GT20-TM) and a tilt/swivel mount . The extremely sensitive GPS receiver allows you to easily mark down the best fishing spots, create maps with 0.3 meter contours, and check your speed.
