Airmar TRIDUCER
multisensors incorpo-
rate a revolutionary self-closing valve to min-
imize water flow into the boat when the
paddlewheel insert is removed. “Gushers” are
eliminated with this simple to maintain valve.
Fins provide on either side of the paddlewheel
for more accurate speed measurement in
cross-flow conditions.
Combined with our fairing, installation is
made simple. Made of urethane, the fairing
will never swell or rot, and the unique cutting
guide allows safer, more accurate cutting with
a band saw. High speed fairings are provided
with a corrosion resistant bolt to secure the
fairing and prevent rotation.

New B744V and long stem B744VL offer flush mounting in streamlined fairings
and accommodate ceramics up to 44 mm (1.75
"
) in diameter including the
popular 50/200 kHz model
SS544 includes a streamlined fairing and is designed specifically for isolated
mounting to steel and aluminum hulls. It accommodates ceramics up to 44 mm
(1.75
"
) in diameter
New streamlined fairings for B744V, B744VL, and SS544V provide much improved
echosounding at speeds above 20 knots and greatly reduce drag
Versatile B66V and long stem B66VL mounts frequencies varying from 50 kHz to
200 kHz including dual beam 120 kHz and dual element 50 kHz & 200 kHz
Optional
paddlewheel-less
