B744V Thru-Hull Triducer 600kW, 50/200kHzThe B744V Triducer Multisensor provides you with depth, speed, and temperature in one thru-hull housing. This unit is ideal for all 600 Watt fishfinders and requires only a single hole in the hull. The B744V's valve assembly prevents water from rushing into the hull when the insert is removed for cleaning or storage. The innovative housing design allows the TRIDUCER Multisensor to be fully recessed into its custom High-Performance Fairing. The end result is a streamlined installation. At speeds above 30 knots (34 MPH), the B744V will produce clear images and solid bottom tracking.Features:Thru Hull Bronze HousingFrequency: 50/200 kHzCone: 45°/12° Depth, speed, and temperature in one housingMaximum depth range 50 kHz 235m to 353m (800' to 1,200') - 200 kHz 118m to 206m (400' to 700')Greatly improved high-speed performance at both 50 kHz and 200 kHz when installed with a high-performance fairingSelf-closing sea valve reduces water flow into the hull when paddlewheel insert is removedSpeed Operating Range: 1 knot to 45 knots (1 MPH to 52 MPH)The extra length of the B744VL allows mounting into thicker and/or high deadrise hullsBoat Size: 9m (30') and upSpeed insert is easily removed for service or storageFins on sides of paddlewheel cavity improve accuracy at low speeds and in cross flow conditionsValve assembly is replaceableAirmar's fairings are easy to cut and will not swell or rot 8 pin connectorShielding eliminates interference between the speed and depth sensors for more accurate instrument readings Fishing Applications:Inshore or coastal fishing in shallow to medium depthsSlow trolling, structure fishing and drifting Deep-water lake fishing
