Raymarine ST60 depth alarms

[cpedw]

My new boat has ST60 Tridata depth. It has shallow and deep alarms and shallow anchor and deep anchor alarms. Is there more to these anchor alarms than the same again, but allowing 2 depths to be preset for shallow and for deep alarms? The manual doesn't seem to tell me much apart from this :
"An alarm condition occurs if:
• The depth is less than the SHALLOW or SHALLOW anchor threshold.
• The depth is greater than the DEEP anchor threshold.
• The depth crosses the DEEP threshold."
but that doesn't help me at all.

I turned all those alarms off on my ST60 as they just annoyed me and I couldn't fathom the instructions.

There are much better tablet/phone anchor alarms based on distance moved from anchor point rather than changing depth.

Ha!

Me too. Just what you need when manoeuvring in a tricky spot is an alarm beeping at you.

The "normal" alarms are on all the time, so if you stray into shallow water without noticing, you will be alerted hopefully before hitting the putty. The anchor ones are only on when you turn them on.

I use the alarms as follows:
Shallow alarm at 2m below keel to alert me of shoaling depth, switched off at anchor
Deep alarm off
Shallow anchor alarm at 0.5m, switched on at anchor only
Deep anchor at 3.5 times scope, switched on at anchor.

Essentially, the anchor alarms are there to save you having to adjust shallow / deep settings everytime you anchor.

That's my take on it, anyway. I'm surprised others don't use the shallow alarm, at least. I felt very uncomfortable without it when it was faulty, though I suppose it is of limited value in steep sided, rocky waters.

I can switch each of the four alarms on or off independently.
I think Quiddle's explanation describes how they are intended to be used but I'm joining Nigel & Richard's camp and leaving them all off most of the time.
