Fish Finders and Depth Sounders

An essential part of any fishing boat electronics system, fish finders and depth sounders locate fish, map lake and sea beds, and produce depth maps of up to 900 feet or more. By trailing a transducer beneath your boat, you are sending out and receiving sonic waves that let you ‘see’ beneath the surface.


Portable handheld fishfinders are the most mobile, and some are small enough to fit in your pocket. Other options include dash mountable options, which provide more stability. Multifunction fish finders and depth finders also double up as complete satnav solutions that people can use anywhere, even in cars. Some sets come complete sounders, transducers, and even waterproof covers to help keep the equipment in tip-top condition.


With Wi-Fi connectivity, you can download software updates and maps directly to your sounder instead of messing about with wires and laptops. However, Bluetooth connectivity allows you to upload to other devices wirelessly to increase your storage. Some units allow you to expand storage via a Micro USB card. With chirp sonar, you can produce full 3D imaging to produce superior maps of shallow lakes and sea beds for easy navigation. Some units come with a built-in antenna allowing you to access marine radio while on the move, while others let you control the unit with smartphone interface.

User Interface

Many sounders have an application-style interface that you can tap to get the information you need. Featuring full touchscreen functionality and smartphone connectivity, these units offer great controllability from multiple devices; especially useful if you install a dash-mounted sounder. Images range from monochrome to full colour, but all give you high-quality visibility so you can avoid shallow water or find the next ‘one that got away’.


Most fish finders and sounders come with at least a one-year manufacturer’s warranty so you can buy with confidence, knowing that if there are any manufacturer defects, you can replace your unit or have it repaired.
