Tilted Element Thru-Hull, Minimize Your Drag, The B619 model have been the standard in low-profile models for many years. Their large sensitive ceramics allow deep echosounding up to 206M (700"). These nearly flush units minimize drag as only 5mm (2/10") of the housing extends outside of the hull. The bronze B619 provides a vertical beam without a fairing. Inside the housing, the ceramic element is tilted to provide built-in deadrise compensation. The resulting vertical beam provides excellent echo returns for moreaccurate depth readings. Applications, Cruising powerboats and sailboats, Sailboats. Features, Depth only or Depth and temperature, Fixed 12° tilted versions for 8° to 15° hull deadrise, Right angle cable exit offers low headroom and protection when transducer is stepped on, Included rubber washer allows tightening of the hull nut to irregular hull surfaces, Housings are ABYC H-27 compliant, Optional temperature sensor, Bronze housing, Boat Size: Up to 9M (30").
