What Are Marine Electronic Fish Finders?

Fish finders (or sounders) use sonar technology to locate fish, identify seabed structures, and measure depth. They emit sound pulses that reflect off underwater objects; the returning signals are translated into real-time images on your display.

This technology helps anglers:

• Pinpoint schools of baitfish and predators.
• Identify reefs, drop-offs, and wrecks.
• Track depth and temperature changes.
• Maximise time spent fishing productive areas.

In New Zealand’s diverse coastal and freshwater environments, a quality fish finder is essential for safety, efficiency, and success on the water.

Our Range — From Kayaks to Yachts

Action Outdoors supplies fish finders for every vessel size and budget. We stock entry-level models perfect for kayaks and runabouts, as well as professional-grade sonar units for large launches and commercial boats.

Screen Sizes and Options

Choose from 9-inch, 10-inch, and 12-inch high-definition displays, offering clear visibility in bright sunlight or low-light conditions. Touchscreen and split-screen functions allow you to view depth, GPS position, and sonar imaging simultaneously.

Mounting and Installation

We provide systems suitable for:

• Kayaks – compact, lightweight units with battery packs.
• Trailer boats – dash-mounted combo units.
• Launches and yachts – networked multi-display systems integrated with radar and chart plotters.

Our team can help you select the right configuration and transducer type for your boat and fishing style.

Advanced Sonar Technologies

Today’s marine electronics offer several sonar options, each suited to different water depths and fishing conditions:

Traditional Sonar

The classic single-beam sonar that displays arches and depth readings. Great for general fishing and basic depth detection.

CHIRP Sonar

Compressed High-Intensity Radar Pulse (CHIRP) sends a range of frequencies for increased target separation and detail, allowing you to distinguish individual fish close to the seabed.

DownScan Imaging

Provides near-photographic images directly below the boat — perfect for identifying structure, vegetation, and bottom hardness.

SideScan Imaging

Covers large areas on both sides of your vessel, ideal for scanning reefs or locating schooling fish without passing directly overhead.

Live Sonar and 3D Imaging

The latest technology displays real-time fish movement and terrain contours, letting you watch how fish react to your lure or bait.

Action Outdoors stocks the newest models from Lowrance, Simrad, and AdvanSea, ensuring our customers access the latest sonar innovations for Kiwi fishing conditions.

Navigation Integration and Chart Plotters

Most of our fish finders are combination units that also function as GPS chart plotters, giving you total situational awareness. Plot, record, and return to your most productive fishing spots with pinpoint accuracy.

Electronic navigation charts feature detailed bathymetric lines, 3D seabed imagery, and auto-routing functions that simplify safe travel through harbours, reefs, and offshore channels.

Transducers — The Heart of Every Sounder

Choosing the right transducer ensures accurate readings and maximum performance.

We stock a wide range of transducers in 600 W to 1 kW+ power ratings, suitable for:

• Shallow coastal and estuary fishing.
• Deep-drop and offshore game fishing.
• Kayak and in-hull installations.

Our experts can recommend the correct frequency setup (50/200 kHz, CHIRP, or dual-beam) to suit your vessel and target species.
