DST800

[kechikan]

Hello,
I would like to add a retractable triducer to my system,
Actually I have a itc5, I70, a65, a67, EV1, ACU100 and a p70 connected to a back bone.
I also have an old retractable seed and temp transducer ST800-P120 y would like to replace for the triducer.
¿are all plastic DST800 retractable?
¿Which model will fit in the housing for the ST800 and be conected to the ITC-5?
I know there is a model to be connected directly to the backbone, if I have the ITC-5 ¿is there any advantage on choosing this one instead of the one connected via ITC-5?

For the a67 I will be using a A80171, but I still want to be able to navigate only with the instruments on, and not the MDF, ¿will I have any interference when the two transducers are on?

Thank you

Welcome the Raymarine Forum kechikan,

Q1. Are all plastic DST800 retractable?
A1. All DST800's sold by Raymarine are designed to be retractable.

Q2. Which model will fit in the housing for the ST800 and be conected to the ITC-5?
A2. I would recommend that this question be referred to the manufacturer of both the ST800-P120 and DST800 (Gemeco, Inc. (Airmar’s US distributor (803 693 0777))).

Q3. I know there is a model to be connected directly to the backbone, if I have the ITC-5 Is there any advantage on choosing this one instead of the one connected via ITC-5?
Q4. Yes. The Smart DST800 is designed to ping at 235kHz, thereby reducing the possibility of interfering with or being interfered by other depth / fishfinder transducers.

Q5. For the a67 I will be using a A80171, but I still want to be able to navigate only with the instruments on, and not the MDF, Will I have any interference when the two transducers are on?
A5. See the response to Q4. The A80171 P319 fishfinder transducer is designed to ping at 50kHz and/or 200kHz. Should an analog DST800 (pings at 200kHz) be installed, then interference from the P319 may occur should the MFD's Fishfinder application be configured to use the 200kHz channel.
