Take your offshore fish-finding performance to the next level with the Lowrance S3100H Sonar Module. Designed for serious anglers who demand clear, consistent sonar information in challenging conditions, the S3100H adds advanced sonar processing and heave compensation capability to compatible Lowrance marine electronics systems. For deep-water fishing, game fishing and offshore applications, boat movement caused by swell can make it difficult to accurately interpret bottom structure, fish targets and depth. With a correctly configured compatible system, heave compensation helps account for the boat's vertical movement, producing a more stable and easier-to-read sonar picture. Key Features Advanced sonar processing for demanding offshore applications Heave compensation capability with compatible equipment Helps produce a more stable sonar display in swell and rough conditions Designed for integration with compatible Lowrance marine electronics Multiple network connections for integration into larger electronics systems Ideal for deep-water, offshore and game fishing Excellent upgrade for boats running high-performance sonar and transducer packages Rugged marine construction designed for permanent onboard installation Why Heave Compensation? When your boat rises and falls with the swell, conventional sonar can show the bottom moving up and down on the display. This can make it harder to distinguish genuine bottom changes and fish targets from movement caused by the boat itself. A properly configured heave-compensated system can account for this vertical movement, helping provide a steadier representation of the seabed and targets beneath the boat. For anglers fishing deep reefs, pins, drop-offs and offshore structure, this can make sonar information considerably easier to interpret. Built for Serious Sonar Systems The S3100H is an excellent option for anglers building a more advanced Lowrance electronics package. It can form part of a professionally integrated system incorporating compatible multifunction displays, transducers, GPS and heading sensors, networking and other marine electronics. Choosing the correct transducer and system configuration is critical to getting the best performance from any advanced sonar setup.
