Fishfinders or more recently known as Multi-Function Displays (MFDs), allow anglers to see a graphic representation of what is beneath their boats so they can identify fish.

As technology has advanced in recent years, many MFDs now combine not only the traditional Fishfinder, but also a chart plotter, and wide array of networkable accessories like high powered sonar modules, radars and the WIFI/Bluetooth features of a true smart device.

To choose a Fishfinder, you’ll need to consider the following things:

• Type of unit
• Whether it includdes GPS and is part of a boat wide network
• Size of the Fishfinder’s footpriint
• Resolution of the display
• How much transmitting power you need
• What frequencies will work best in the lakes, estuaries, shallow or deep-water environment where you fish

Ask yourself the following questions.

Do you:

• Know your local fishing spots well and want a standalone Fishfinder to show you where the fish are holding?
• Want a combination Fishfinder/chartplotter to safely explore somewhere new saving waypoints along the way to return next time?
• Need a high-powered networked system with multiple big screens, radars, autopilot, communications and a range of sonar options?

Standalone Fishfinder:

If you just want to see what’s below, dedicated Fishfinders give the biggest display and the best performance for the least cost.

Suitable for:

• Small boats
• Inland lakes
• Estuaries

• Sonar
• Charting
• High definition structurescan
• Autopilot controls and audio integration Wifi / Bluetooth
• Smartphone / tablet combatibility (call / text notification)

Features:

• Support a huge range of data sources
• Full engine integration
• Radar
• Raster & Vector GPS charts
• Video integration
• Digital switching options
• High powered

What Style & Shape?

Thru-Hull

While they can be the most challenging to install, they are likely to provide best signal quality. Displacement power and sailboats generally use thru-hulls. A thru-hull triducer contains depth and temperature sensors, plus a speed paddle wheel.

Transom-Mount

Adjustable-angle bracket is screwed or bolted to transom, with transducer hanging below and behind hull. Simpler installation, but may encounter more turbulent water flow.

In-Hull

Very popular for Jetskis and both in-hull and transom-mount styles are popular for trailer boats. “Shoot through hull” transducers need no direct water contact. They are glued to the inside of the hull with silicone or epoxy. They do not work on cored hulls or steel hulls, only for solid fiberglass.

Trolling Motor

Clamped to the outside or permanently installed inside propeller hub of trolling motor. Sonar Ready trolling motor models include built-in 200kHz transducers that fit many popular fishfinders.
