    Purchased a 2006 52DB late last fall. Just thinking what I want to do with electronics. It has a SRN that does not work. Can't seem to find out what it does. So, what exactly does it do, and do I need to replace it?

    Thanks,
    Tim

    It is really nothing more than a PC with raster format charts loaded and an interface with NMEA 0183 instruments. And it is painfully slow compared to a Raymarine E series with poor resolution. I don't think you can get charts for it anymore.

    HA! Thanks for the info. Can I simply pull it out and put in another E120?

    That's exactly what I did back in 2018.

    Did everything work correctly, or did you have to change the transducer? Simply plug and play?

    Transducer - assume you mean the depth transducer right? If so my boat had separate transducers for the Raymarine and the Navigator so I didn't reconnect the transducer. Regardless as it is NMEA 0183 you can use it with the Ray E120.

    Be mindful of the difference in footprint. I had to order a new helm panel from Technographics because the E120 is smaller than the SRN height wise.

    We swapped out the Navigator with another E120 and went with a replacement grey panel from Flounder Pounder. Sadly our depth transducer was going to the SRN so we had to update that. Otherwise it all worked. E120's are 2006 vintage and we keep the Navionic charts updated, but the rocks haven't moved. We got a few hundred bucks for a working SRN from a guy that refurbs them, https://www.nsiworldwide.com/srni3repair.shtml

    I tried selling mine to Mark a couple times but he never responded so I threw it in the trash where it belonged.

    He bought mine from my 52 and my 55(58). I threw away the map tech open array radar though because it was too expensive to ship anywhere.

    So did the SRN transducer also have a paddle wheel speed sensor as well? I couldn't believe my eyes during survey, that I had a paddle wheel on the bottom of my boat..... It even still freely turned!

    The paddle wheel is the only way to get Speed Through Water (STW). The GPS gives you Speed Over Ground (SOG). They are never really the same since there is always some sort of tide (except lakes). The two of them one minus the other will give you the tidal (current) speed. With the tide would be SOG - STW = speed of the current. If your drifting your STW (paddle wheel) would be 0 and the SOG (GPS) would be what ever the current is moving at.
