Kobus,I agree with you on building things up yourself, but a lot of people won't want to go through the work. BTW, Airmar is a wholly owned subsidiary of Amphenol Corp., not Garmin. You can buy from them directly and get tech support from them (and they're responsive and support their old products). The (old) RayMarine speed/depth/temperature sensor is actually made by Airmar and set up to talk SeaTalk (no, not SeaTalk II which is essentially NMEA-2000). They make these sensors for a lot of the navigation system manufacturers.What are you running OpenCPN on? The nice thing about this is that you can run it on an off the shelf laptop, if you want, or a dedicated board (like a Raspberry Pi board running Linux). I have a couple of older laptops sitting around, so I can have backup systems available.A couple of years ago, I picked up a Davis anemometer made for a household weather station. I found a site with code for the Arduino board, but I pushed the whole thing to the background. Recently, I have revived my project and modified the code a little. I want to feed this into Signal K and OpenCPN.I have been using Navionics on an 8" tablet at the helm, but you can set up your OpenCPN system with a VPN and display it on a waterproof tablet at the helm. That's not really much different from what I have seen for B&G or RayMarine systems with a computer at the nav station and another display at the helm.------------------------------------------------------------------

I have a whole suite of Raymarine products but I will never do that again. Also no more full Garmin or B&G system. Will cherry pick things like radar etc but no more expensive chart plotters. OpenCPN and Navioncs (or similar app) will do.I will build my open source system with select brand pieces like the Garmin Airmar transducer. Told a friend and heinstalled it and is very happy with it.

It seems like the Ideal spot for the new (Airmar DST810) transducer would be on the centerline in the (easily accessible) space between the fresh and black water tanks… about 8” forward of the existing through-hull. This would entail cutting another hole in the hull... and patching up the two that aren't used anymore. The easier route would be to use the existing hole from where the currently broken speed transducer is… but, as I mentioned, it doesn’t clear the black water tank, and if I can’t swap it out before haul out (or in an emergency) this whole scenario might happen again.
Does anyone have some perspective? Worth it to drill a new hole in the boat to make it happen? Better to use the existing hole and get sailing already?
Thanks
