Depth sounder struggling

[prv]

That is speed, shouldn't affect depth in any way.

Paddlewheels don't click. He means that while he was fiddling with the speed paddlewheel, he could hear the depth transducer next to it (it's a combined unit, that's what DST means) emitting pulses.

Personally, once I am over the 10 meter contour I really don't care what the depth is.

Old guys like me still regard the echo sounder as another source of position information, particularly in poor visibility and when there's enough variation in bottom contours so the soundings give meaningful clues.

But only useful if there's useful sea-bed topography; if the sea-bed is fairly flat, it doesn't help much. And, of course, if the sea-bed is below the range of your echo-sounder - not likely where I currently sail, but a factor when I sailed on the Clyde!

Of course. I completely misread. Silly me!

Speed - yes, temp - good question!

Temp for Autohelm kit is part of the log and if it packs up the speed is wrong, depth is okay.

It's a combined unit depth, speed and temperature

 

[Lucky Duck]

ah, speed and temp are working properly?

I cant find sea temp anywhere on the network

However I have no idea if it has always been like that

 

[vas]

if its a DST there must be temp floating in the bus. What devices have you got in your NMEA2000 bus? Any 4in small display could be configured to show that, same with plotters I'd have thought. You may have to go through your manual to configure a screen to show it.

 

[Lucky Duck]

I have checked the data coming from the unit (speed/depth/log) and searched for temp on the network to no avail.

 

[vas]

How exactly did you check, what gauges do you have on the bus? I'm assuming you do have an NMEA2000 bus.

 

[Lucky Duck]

Using the network 'tools' on the MFD (Zues 2) and one of the displays (Triton)

Network is entirely N2k

Has the OP checked for fouling?

 

[Lucky Duck]

Launched two weeks ago, but I will give the sounder a wipe just in case.

Edit - seems the sea temp failure is a know issue reading other forums

 

[Lucky Duck]

Is it normal for it to pulse 8 times then a brief pause before resuming?
