At East Coast Marine Electronics, we specialise in professional fishfinder installation for recreational and offshore boats throughout Tauranga, Bay of Plenty, Coromandel, Rotorua, and across New Zealand.

Whether you’re upgrading an older sounder or fitting out a new boat, a fishfinder will only perform as well as it’s installed. We focus on correct transducer selection, precise placement, clean wiring, and full system setup to ensure you get clear, reliable sonar performance every time you head out.

Professional Fishfinder & Sounder Installation

We install modern fishfinders and sounder systems to suit all types of boating and fishing, from inshore and freshwater through to serious offshore and game fishing.

Our fishfinder installation services include:

  • New fishfinder installations

  • Fishfinder upgrades and replacements

  • Single or multi-screen setups

  • Networked systems with sounder modules

  • Flush-mount and custom dash panel installations

  • Full configuration and on-water setup

Every install is tailored to your boat layout, hull type, and fishing style, not a one-size-fits-all approach.

Transducer Selection & Placement Matters

Correct transducer choice and placement is the most critical part of any fishfinder installation. Poor placement can result in signal loss, noisy readings, and poor depth performance.

We specialise in:

  • Thru-hull and transom-mount transducers

  • High-power offshore and deep-water transducers

  • Inshore and freshwater transducer setups

  • Fairing block installations

  • Hull-specific positioning for clean water flow

We take the time to ensure your transducer is mounted in the best possible location to deliver maximum clarity and depth performance in real-world conditions.
