I'll search the planet for the SL-1, but now I'm wondering if I should just get a matching ST-40 speed/temp (or speed only) to match my Raymarine Depth and remount both on a nice piece of teak, one over the other......Both have 4" holes behind them. The PO put a white rectangular, thin block over the lower one for the ST-40 Depth, and a Round Teak "patch" over the 4" upper.
Don't want to replace the ST-40 Depth, it works fine, so leaving well enough alone. The idea of a tri-data is nice, but what do I do with a redundant depth.......just collects dust since I really can't sell it (and don't want to pull out the transducer and reglass>>> what a pain!
Thanks to you both. We'll see what happens. Nothing urgent has to be done.
Tiny hint: The info you posted indicates the transducer Model you have is an SIA15 - an old Standard Horizon part no.
Rob, I guess the best things about Raymarine are that (a) their gear is generally pretty good and (b) they are still around.
If you're after Speed, as I see it, you have two choices:
1. Buy an ST40 Speed, cut the holes and hook it in.
2. Repalce your existing ST40 Depth display with the Bidata. It's the same cut-out. Connect up both your old depth transducer and the new speed one to the Bidata. Sell the old ST40 Depth on EBay, with the brand new depth transducer out of the box..
Cost-wise, the Bidata option is going to hurt the wallet more initially - at least you wont have to drill any more holes ...but some people prefer the large-digit readout from two separate displays - each to their own.
The ST40 range also supports Seatalk so whichever way you go you can link the devices to something else inside (like a chartplotter) should you later wish to.
From RFC 1925: "(3) With sufficient thrust, pigs fly just fine. However, this is not necessarily a good idea. It is hard to be sure where they are going to land, and it could be dangerous sitting under them as they fly overhead."
