Lowrance S3100H Sonar Module

The Lowrance S3100H is a dual-channel 1kW sonar module for boats that need Active Imaging HD and CHIRP expansion. It is designed to work with HDS PRO, HDS Live, HDS Carbon, and Elite FS displays, adding FishReveal SideScan support when paired with an HDS PRO and Active Imaging HD transducer. This is a module only, not a display or transducer kit.

Two independent 1kW sonar ports let the installation run one or two compatible channels, depending on the display and transducer arrangement. The module accepts 12-24V DC and is intended to sit within a Lowrance Ethernet network. FishReveal SideScan is not created by the S3100H alone; the compatible display and Active Imaging HD transducer are essential. Confirm the display generation and transducer before planning the system.

Who Is This For?

This Lowrance 1kW sonar module suits serious fishing boats upgrading a compatible HDS or Elite FS network. It is not ideal for buyers expecting a screen or transducer, because both must be supplied separately and FishReveal SideScan requires the specified display and Active Imaging HD hardware.

Warranty & Support

Lowrance provides a 2-year standard warranty. The supplied specifications do not state warranty exclusions or service procedures.

The S3100H is the expansion module for a Lowrance system that needs more sonar power and channel flexibility. Its trade-off is that it adds no value without the correct display, Ethernet connection, and transducer. Choose it for an HDS or Elite FS upgrade where dual 1kW sonar and FishReveal matter, not as a standalone fishfinder.
