Thank you and we look forward to hearing from you!
Airmar's P79 in-hull transducer easily adjusts to hull deadrise angles up to 22°. This ensures that the beam is vertically oriented to receive echos resulting in accurate depth readings. Unlike traditional "puck" type transducers, our P79 consists of a base that is bonded to the hull and filled with liquid. The separate transducer then attaches to the base with a twist lock. The sound waves travel more efficiently though the liquid, giving the best possible performance.
Planing Hull Powerboats
Aluminium Hulls less than 1/8" thick
Excellent Performance in Shallow Water Boats
Excellent Bass and Jet boat Performance
In-hull installation over solid fibreglass only
Good target detail in shallow water at 200 kHz and good deep water bottom tracking at 50kHz
In-hull mounting eliminates turbulence under the transducer's face resulting in clear bottom images- even at boat speeds above 20 knots
Innovative two piece design allows the transducer to be easily removed for service or storage No adhesive layer between transducer face and hull to absorb sound waves
