Good morning, I would like to replace an old Autohelm ST30 Bidata display, which works but no longer communicates, while retaining the original speed and depth probes. I think the DST 2 module would be suitable but I don’t know which frequency to choose (150 – 170 – 200 kHz etc.). Could you advise me please? Fred.
Hi Fred, The frequency of the DST-2 that you would want is usually determined by the frequency of the depth transducer that you have. Tt would either be a 150/170/200 Khz transducer, and you’d need the corresponding DST with the matching frequency. If we can help further, please just raise a ticket in our Support Centre and we’ll be delighted to help. Kind regard, Justin
