Double Depth Finder.

Welcome to the Raymarine Forum Daniel,

The ST60 Depth and ST60 Tridata Instruments may be used with any of the analog instrument depth transducers found here. As the devices supporting first generation SeaTalk only supported one instance of each type of data, the two depth instruments should not be interfaced to one another. However, should you desire to power the second ST60 Depth Instrument from the same SeaTalk bus which is powering the first ST60, then only the red and shield leads of the SeaTalk Cable connecting the second ST60 should be used. This may require that the SeaTalk Cable be cut and then spliced back together, leaving the yellow leads not spliced and insulated to prevent shorting.

As the instrument depth transducers will both operate at 200kHz, it is possible that they may interfere with on another ... however, the amount of separation which you have specified may reduce the chances of interference. Accordingly, you may want to performing a test by suspending the depth transducer over the side before permanently installing the transducer.
