I have an aged Stowe Echo Sounder. Can anyone tell me what the "Anchor Watch" function does? I suspect that it might have a pre-set change of depth that triggers the alarm.
I usually set the Deep and Shallow alarms to suit the conditions, but I can't figure out the Anchor Watch.
Thanks in advance for any help.

As I recall (its over 5 years since I last used a stowe instrument) the anchor watch alarm will sound if the depth exceeds an amount you specify

No, there doesn't seem to be any way of setting it. It sticks up a funny symbol, and that's it.
I should set it and drive around a bit and see what happens. I'm only curious, 'cos between shallow/deep alarms, gps alarms, squinting out of the window every five minutes at transits I'm not too bothered.

According to my Stowe Dataline-X SDX manual.

"The anchor alarm does not monitor depth for a minimum or maximum value, but sounds if the change in depth exceeds a set rate. It can be used together with one or both of the shallow and deep alarms"

The rate of change appears to be preset, and presumably is coarse enough to account for tide rise/fall.

Right, this makes sense. We were starting to think it might sound after, say, a change of 10 units or something, but that wouldn't work. A "rate of change" would, though. Thanks. All we need now is to know what that rate is!!

Fraid It doesn't say, but I'm sure it is > than normal tide variation but < a value to get in trouble. Try Simrad, they have been useful with my questions in the past even though no longer supported. You could even try the nasty man at AW Marine.
