B744VL Long Stem Bronze Thru-Hull D/S/T with FB 8-PinThe B744VL is a TRIDUCER Multisensor featuring depth, speed, and temperature in a single housing. The 50/200 kHz, dual-frequency, single, ceramic element provides great target detail in shallow water at 200 kHz and good deep-water bottom tracking at 50 kHz. The B744VLs extended stem length has the extra height needed for steep-deadrise vessels or thick, cored-fiberglass or wood hulls. The required High-performance Fairing gives excellent results at speeds up to 30 knots (34 MPH).Features:Depth, speed, and fast-response water-temperature sensing in one housing600 W of powerDual-frequency element:50 kHz with a wide 45 beamwidth for depth performance to 353 m (1200′)200 kHz with a 12 beamwidth for depth performance to 206 m (700′)Extra-long stem for thick or steep-deadrise hullBronze housing with a High-performance Fairing for optimal bottom tracking at higher speedsSelf-closing water valve reduces water flow into the hull when the paddlewheel insert is being replaced with the blanking plugFins on the sides of the paddlewheel cavity provide improved accuracy in cross-flow conditionsAlso available with a shorter stem (B744V)Specifications:Power Rating: 600 WMax Deadrise Angle: 24Housing: BronzeFunctions: Depth, Speed, TemperatureHull Material: Fiberglass or woodMax Vessel LOA: Up to 9 m (30′)Hole Size: 51 mm (2″)Usable Shaft Length: 140 mm (5.50″)Acoustic Window: UrethaneCommon Use: Leisure/Yachting, FishingConventional Beam: 45/12Max Deadrise: Up to 24 with fairingMax Depth: Low frequency- 366 m (1200′), High frequency- 206 m (700′)Mounting Style: Thru-Hull with FairingRetractable housing: YesSingle or Dual Frequency: Conventional Dual FrequencyTilted Element: NoWeight: 2.5 kg (5.5 lbs.)
