Description
Garmin’s Fairing Block is used to position your thru-hull scanning transducers parallel to the water for increased sonar accuracy. This Fairing Block is compatible with Garmin’s GT21, GT23, GT41, GT50 or GT51 series of thru-hull scanning transducers. If the deadrise angle of your mounting location exceeds 5 degrees, you should use a fairing block to mount the device.
