LOW COST
 Click to Enlarge Image
Available in five different frequencies the design has nineteen piston elements arranged in three concentric rings to provide a high performance, dual beam Transducer.

Continuing the company's successful policy of offering transducers with a choice of frequencies the 153 SERIES gives the customer maximum flexibility with minimum cost.

The design is also available as a single, narrow beam transducer.

The versatility of the design is further enhanced with the option of a ground discriminating ’GD’ feature where additional knowledge of the sea floor texture is important.
