Simrad S3100H Sonar Module

Powerful black-box sonar for clear detection of bottom, structure, and fish at greater depths.
The S3100H is a networkable CHIRP sonar module that connects to compatible Simrad multifunction displays via Ethernet. The unit processes the signal from separate transducers and provides high-resolution images at great depths. Through external processing, the S3100H offloads your main display and delivers significantly better sonar performance than an integrated sounder.

The module supports 50/200 kHz transducers and is a logical choice for those who want to improve the sonar capability of a Simrad system without replacing the entire MFD.

Why choose the S3100H?

• External sonar processing: higher signal quality and wider range than built-in MFD sonars.
• CHIRP technology: clear target discrimination and less noise than classic sonars.
• Ethernet connection: direct connection with multiple displays in a Simrad network.
• Black-box design: compact module for hidden installation on board.
• Broad compatibility: works with traditional 50 kHz and 200 kHz transducers.

Who is this product for?

The S3100H is intended for anglers, charter operators, and serious recreational users who want to improve the sounder performance of their existing Simrad system. Suitable for deep-sea fishing, navigating deeper waters, or wherever accurate bottom detection is crucial. Works seamlessly with multiple Simrad NSS, NSO, NSX, and compatible MFDs in one system.

What does it offer you?

• Better underwater visibility: more detail, sharper images, and greater depth than an internal sounder.
• Faster bottom readings: CHIRP signal for immediate target distinction at any depth.
• One central sonar for the entire system: image visible on multiple MFDs simultaneously.
• Future-proof installation: expandable without replacing the MFD.
• Clean cabling: module hidden away, with only Ethernet and transducer cables visible.
