The Navico (B&G, Simrad, Lowrance) P319 transducer is a compact, plastic, thru-hull, dual-frequency (50/200 kHz) sensor that offers depth and temperature data. Ideal for planing hull powerboats and sailboats.
-Requires just one hole in the hull to receive data for both depth and temperature.
-Works at 50 kHz and 200 kHz for good target detail in shallow water and excellent bottom tracking in deep water.
-Provides extremely accurate data.
-Just 5mm extends outside of the hull.
