Three in one! Only one thru-hull needed and this combination transducer will provide you with precise information on depth, speed and water temperature. The transducer comes with a thru-hull / ground sleeve for installation in the ship's bottom. The transducer can easily be pulled out for cleaning and maintenance. The ground sleeve can be sealed watertight by means of the supplied blind plug.The AIRMAR Triducer provides data for speed, depth and temperature via the standardized NMEA protocol. Thus, the transducer can be connected to all devices such as plotters (e.g. VDO, Techmarine, STANDARD HORIZON), multifunction devices or computers etc. with suitable port. It turns your plotter into a true multifunction device.Measuring range: water depth 0.4 to 65 mBoat speed: up to max. 44 knWater temperature: 0-33°CBore diameter: 51 mmOuter diameter: 75 mmHeight: 111 mmSupplied with installation sleeve and connection cableInstallation sleeve optionally available in bronze or stainless steel Spare paddle wheel available upon requestNote regarding electr. connection: white = NMEA Out+ / blue = NMEA OUT- (Signal Ground -) / red = +12V / black = -12V.
