Adjustable
120 kHz, 200 kHz, 235 kHz, 50/200 kHz Dual Frequency
Patent Pending
Specifications
• Excellent high-speed performance to 60+ knots (69+ MPH) when mounted
well aft
• No thru-hull penetration
• Housing material is a chemically resistant, high impact, plastic alloy
• Design has shielded piezoceramic element for noise free echo
sounder display
• Superior acoustic sensitivity when using large PZT piezoceramics
• Standard Cable length: 1m (3.4’) pigtail with in-line connector off of
transducer; 6 m (22’) extension cable
• Weight: .9 kg ( 2 lb.)
Options
• Epoxy kit #33-156
• Protective base cap, which is especially useful for boat builders
Applications
• Fiberglass hulls
• Not suitable for wood hulls
• Planing hull powerboats
• Aluminum hulls less than 1/8" thick
New
• IN-HULL MOUNT • Adjustable
Easily adjusts to any deadrise angle up to 22
°
Transmits sound waves directly at the bottom so strong echoes are reflected
back to the transducer
Can be removed in seconds for servicing or storage
Only the base piece is bonded to the hull. There is no adhesive layer
under the transducer face to absorb sound energy
Simplifies in-hull installation
