When choosing your new fishfinder transducer please review its composition, how it is mounted and what you want to see displayed.  Its composition is the material it is made of:  plastic, bronze or stainless steel.  Plastic fish finder transducers are recommended for fiberglass or metal hulls.  Bronze are recommended for wooden or fiberglass hulls.  Wooden hulls expand and contract and could damage a plastic transducer and cause leaks.  A metal housing should not be intsalled in a vessel with a positive ground system.  Stainless Steel is ideal for aluminum or steel hulls.

Fish Finder transducers are mounted:  in the hull, through the hull, or on the transom.  In-hull are designed to be used in fiberglass hulls.  They shoot through the hull of the boat with no holes being drilled.  Thru-hull are mounted through a hole drilled in the bottom of the boat.  They need a fairing block which allows the transducer to be mounted properly.   And the most common are transom mounted transducers.  Ideal for personal watercrafts and powerboats with outboard, inboard-outboard and jet drives.

Make sure the transducer has the appropriate power and frequencies which match your fishfinder.  Also determine what your fish finder is capable of displaying, such as depth, speed, temperature, or a combination.  Most fish finder transducers show which model they are designed for, but if you are having trouble please contact us at support@premiumfishfinders.com.
