Airmar
M172
Versatile
The versatile M172 uses a custom base for external mounting, or it can be mounted in a tank. This compact housing features two medium to high-frequency elements for unique applications. The low-ringing (lq) versions allow fishermen or surveyors to see bottom structure more clearly and fishermen to distinguish target fish from the bottom.
