Lowrance S3100H Sonar Module with Heave Feature

Add heave compensation

Fish with a clearer picture in all conditions with heave compensation. This added feature automatically counteracts rocky waters, reducing noise on your sonar images and ensuring it’s easy to spot fish and underwater structure even when the water’s churning.

Boost your clarity

By unlocking compatibility with Active Imaging™ HD on more Simrad® and Lowrance® displays, the S3100H introduces enhanced clarity to your underwater views. Benefit from the cutting-edge of CHIRP sonar technology, and get crystal-clear views of fish and structure beneath and around your boat.

Add FishReveal™ to SideScan

The S3100H doesn’t just boost clarity, it also brings additional underwater views. With the FishReveal feature on SideScan you’ll see a more complete picture of the waters around your boat, meaning you’ll never miss another fish.

Track multiple depths

Don’t be limited by the size of your boat. With two fully independent 1kW sonar channels, you can turn your small or mid-sized cruising vessel into a sportfishing powerhouse, connecting two additional transducers to track multiple depth ranges at the same time.

Smaller, more sustainable design

Designed for easy installation and broad compatibility, the S3100’s reduced size means it can be placed almost anywhere on the boat. Centrally positioned for easy access, the updated offset connectors enable more compact, cleaner installations.

And, as we look to safeguard the future of our waters, the S3100’s housing is manufactured using 50% recycled plastics, as part of our ongoing commitment to sustainability.
