The Speed-Reeder Universal Transom-Mount Transducer Bracket is designed for boats which lose depth reading while cornering at speed. Transducers cannot read correctly in turbulent water and OEM brackets do not incorporate enough adjustments to keep the transducer in clean, unturbulent water. Speed-Reeder's unique two-piece design allows for virtually 180 degree of mounting and adjustability on any surface. Even at speed, the Speed-Reeder maintains perfect contact with the water line, so there's no loss or interference. 16-Gauge T-304 brushed stainless steel construction strong for corrosion protection in any marine environment. Stainless steel assembly hardware firmly locks your adjustment in place for a positive and one-time setting.
