Available in a choice of six different frequencies, the 172 SERIES is designed to be compatible with a wide range of vertical depth finding echo-sounders.

With seven pre-stressed piston elements and internal matching transformer the 172 offers a high performance at a low cost.

The high impact strength nylon body provides a mechanically robust, corrosion free transducer suitable for tank, hull or over-side mounting.

The versatility of the design is further enhanced by the option of a ground discrimination ‘GD’ feature providing an indication of the sea bed roughness.
