Airmar P319 Depth Transducer

[swinsail]

Hi Folks! My yacht is fitted with the standard Sailpack of Raymarine ST60 instruments. The Depth unit operates via the supplied Airmar P319 depth transducer. I would like to add a low cost fishfinder to the boat but dont want to add another transducer (steel boat so needs thru-hull transducer). It seems that several fishfinders (Raymarine, Garmin, Lowrance etc) list the P319 as an option for transducer. Since I will either be using the boat as a either primarily a sailing vesel (and hence prefer the simplicity of the ST60 depth readout), or chasing fish (and hence prefer the detailed view of the fishfinder), i was pondering having either unit operate via the existing transducer, but switch between device by having the transducer wired via a 3 pole double throw toggle switch.

My main question is are all Airmar P319 transducers the same, just with different pluge to suit different instruments?

Does anyone see a flaw in my plan (before I go out & buy a fishfinder)?

Greetings and welcome aboard the CF, swinsail.

Welcome Swinsail,
I don't think you could route a transducer through a 3 pole switch, it's just a guess on my part but I would bet the supply from the transducer to the FF unit is NOT merely a wire!, the B319 is a 500w 50/200hz duel frequency unit.
Possibly you could install a Raymarine sonar module which should allow you to network the transducer into 2 independent fish finders.
I would strongly suggest giving West marine a call, they have advisers who can tell you exactly what you should or could do. see their web site westmarine.com

Are you sure it's the P319? The ST60 gear usually uses the P19.
