What to Look for When Buying a Transducer?

Materials

Transducers are built from either stainless steel, bronze, or plastic – each intended to match the hull elements. Stainless steel transducers are designed for steel, fiberglass, or alloy hulls; Plastic sensors are best for steel or alloy hulls, and bronze transducers are made for wooden hulls.

Beam Angle

A wide-angle beam will help you see more activity beneath your boat. The beam size depends on the transducer’s frequency and the elements of your hull, and the configurations of the transducer.

Operating Frequency

If you plan to fish in shallow coastal waters, a Single Frequency Transducer will work best. However, it would be best to purchase a Dual Frequency Transducer if you go deep-sea fishing.

Output Power

Transducers’ output power is quoted in watts, but do not be fooled; more power is not always more effective. Little power in deep water will give you headaches, while too much power in shallow waters could spell trouble.

Generally, a 100-200 watt range is best for shallow water, while 1000 watts works best when probing deep waters, drop-offs, or canyons. Make sure to check if the transducer is compatible with the power output of your fishfinder.

You also have to consider your budget, the size and material of your boat, and how you plan to mount your transducer.

Transducer Dos and Don’ts 

Whether you’re new to the joys of fishing or have been going on fishing trips for years, here are some do’s and don’ts about transducers to keep in mind.

Keep It Clean

Cleaning your transducer face with a light household detergent every few months will keep marine growth to a minimum and prolong the durability of the transducer.

Turn It Off

Transducers were intended to be used submerged in water, so turn it off when not in use. When sensors are turned on, the chips generate a bit of heat running it above water, or when it’s on your trailer, it will cause your transducer to overheat.

Cables

Make it a habit to check the wires and connectors for corrosion or cuts in the insulation. If damaged, do not intend to use the transducer. Safety should always be your first concern.
