QUICK GUIDE TO BUYING A FISHFINDER

Whatever you learn here, keep in mind a fishfinder is all about catching more fish and that is the main reason why you are buying one. Here are some issues you should consider.

FREQUENCY

Many transducers will come with both 20 and 60 degree cones. The frequencies also are very important for transducers because the higher frequencies perform best in shallow water while the lower frequencies are better for deep water. Look for the frequencies that suit your needs without paying too much.

WATTAGE

The more wattage your fishfinder has, the faster you will see the results and the deeper your readings can be. If you have less power, your readings will be slower and fuzzier, especially at depth.

SCREEN RESOLUTION

This is the issue of pixels on your screen. If you have a low-resolution screen, you will see less detail. For crisper images, you will need a higher resolution.

COLOUR OR BLACK AND WHITE

Colour is the new standard. You should be able to get a colour screen with any modern device unless you are looking for a very low-cost fishfinder.

TRANSDUCERS

The transducer is the main device that emits and receives the sonar waves. Transom mount transducers are the easiest to install. Plastic transducers are fine for casual fishing and compatible with most types of boats. Stainless steel housings are recommended for steel and aluminium hills. Bronze housings are better for fibreglass and wooden hulls.

CONES AND BEAMS

Cones, look just like an upside-down ice cream cone. Wider cones cover a wider area. A 20-degree cone is the best for fishing at different depths. Some transducers work with several cones.

REVIEWS

Verified user reviews are the best way to get an idea of what others have experienced.
