[TG] [TG11] Inconsistent Depth Sounder Performance

[pma_foyl]

Hi There,
I have a ST70 MFD and an AirMar B744V multi-transducer. The ST70 appears to be working fine (it shows consistent wind information and depth info (when it get it).

The problem is inconsistency. At start-up, i'm not getting any depth info. Then, usually after 20 - 40 minutes, the depth info will be presented. I've check my connections and they all seem good. So I'm wondering if this is just a deteriorating/failing transducer.

It may be worth noting that the speed wheel hasn't worked for some time (even though it is moving freely). I realized the depth and speed transducers are not the same, but there may be some connection?? They are part of the same transducer assembly.

Any help or insight would be appreciated.
Thank you,

Paul
