Electronics & Boat Equipment

How to choose electronics for your fishing boat

Boat electronics are best chosen as a system, because the units work best together. A fishfinder shows bottom structure, depth and fish, while a chartplotter shows exactly where you are. A combination unit puts both on the same screen, and you can save productive marks as waypoints to return to later.

The transducer largely decides what you see on the screen. A traditional transducer looks straight down, a side imaging transducer maps a wide strip on both sides of the boat, and live sonar shows the movements of fish and lure almost in real time. Check that the transducer is compatible with your display before you buy.

An electric motor moves the boat quietly over the fishing spot. A bow mount motor gives precise control and suits casting, while a transom mount motor is a simple solution for smaller boats. A motor with GPS anchoring, or a separate electronic anchoring system, holds the boat in place without a traditional anchor, which is a big advantage when fishing a small reef or a wreck.

All of this needs power. LiFePO4 batteries are light and tolerate deep discharge well, but they need a charger designed for them. Plan the battery capacity around your motor and electronics, so the power lasts the whole day.

Safety belongs in every boat. A VHF radio puts you in touch with other boats and the coastguard, and a PLB lets you raise the alarm from almost anywhere. At sea, where mobile coverage cannot be taken for granted, these devices are an essential part of your equipment.
