Know before you buy
The four independent transceivers allow for simultaneous multifrequency operation. This means you can monitor different depths and frequencies at the same time without interference, providing a much more comprehensive view of the water column.
No, the DSM400 is a dedicated sonar module. It does not have built-in GPS or chartplotting features, so it must be connected to a compatible Raymarine multifunction display to visualize your data.
The system automatically adjusts sonar parameters in real-time to filter out surface clutter and noise. This ensures you get a clean, high-definition image that makes it easier to distinguish between bait fish and larger target species.
The DSM400 is a high-performance unit capable of delivering up to 3000 watts of RMS power. It is adjustable, allowing you to select between 1000, 2000, or 3000 watts depending on your specific fishing environment.
The DSM400 is compatible with the SeaTalk hs network. As long as your current Raymarine display supports SeaTalk hs, you can integrate this module into your existing marine electronics setup.
This module is designed for use with professional-grade thru-hull transducers. Because it supports multiple frequencies, ensure your chosen transducer is compatible with the 28, 38, 50, and 200 kHz operating ranges.
