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 B744VL's 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 housing; 600 W of power; Dual-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 hull; Bronze housing with a High-performance Fairing for optimal bottom tracking at higher speeds; Self-closing water valve reduces water flow into the hull when the paddlewheel insert is being replaced with the blanking plug; Fins on the sides of the paddlewheel cavity provide improved accuracy in cross-flow conditions; Also available with a shorter stem (B744V); Specifications:Power Rating: 600 W; Max Deadrise Angle: 24; Housing: Bronze; Functions: Depth, Speed, Temperature; Hull Material: Fiberglass or wood; Max Vessel LOA: Up to 9 m (30'); Hole Size: 51 mm (2"); Usable Shaft Length: 140 mm (5.50"); Acoustic Window: Urethane; Common Use: Leisure/Yachting, Fishing; Conventional Beam: 45/12; Max Deadrise: Up to 24 with fairing; Max Depth: Low frequency- 366 m (1200'), High frequency- 206 m (700'); Mounting Style: Thru-Hull with Fairing; Retractable housing: Yes; Single or Dual Frequency: Conventional Dual Frequency; Tilted Element: No; Weight: 2.5 kg (5.5 lbs.); - cis2:mm5mnJlm -
