OK, so I bit the bullet and brought a new garmin extrex 10 hand held as a backup for my MFD as its independent of power. With the idea that I could use it as a anchor alarm as well. Push the button on the foredeck when the hook goes down... but apparently its not supported by this model, which is strange as it has a marine profile and even man overboard. Anyone from garmin out there ? I don't need maps just a position
 
That would depend on your perspective. My GPSMap 62s runs on rechargeable AA batteries which last about 20 hours a pair. My iPhone would probably last about the same but would then require charging from the house bank. I also trust the software on the Garmin more than an app on a phone, and it's less likely that the app would be closed, because it's not an app. Finally, the GPS with quad helix antenna on my Garmin is better in every way than any phone in terms of both reception and accuracy, and for added reassurance it'll record a plot of my track for reference
 
I've got a decent phone and tried a couple of apps but it keeps waking me up. Unless you make the drift a large area which is toooooo late in Places like Newtown creek...

So you did not read the specification. Why should Gamin respond to your poor research?
 
I have a Garmin gpsmap 78 which has the anchor alarm function, but it had to be turned on somehow. I know it is switched on because it sounds and says “Anchor dragging” while the device is busy acquiring satellite signals after I push the power on button. I think there is a Marine Alarms screen somewhere for controlling it. I will check when I can get to the boat tomorrow.
 
If it doesn’t work maybe look at an old Garmin Colorado model or suchlike which might assist. If anchor alarm is key , separate to the chart plotter can you not buy a stand alone alarm based on gps ?
 
I read the spec and did loads of research and it says it can be done. And doesn't. Not a problem, its going back, just can't find out which model does have that function for under £100
 
Not all Etrex models have the Marine options.

"
Marine Settings
NOTE: This feature is not available for all device models.
Select Setup > Marine.

I have just tried it on my Etrex B&W 20, and it doesn't, but my daughter's colour Etrex 30 does.


Could they have sent you the wrong model ?


With even cheap phones nearly always having decent maps and space for Apps, I now think the handheld GPS such as Etrex are the ultimate backup to the multiple GPS systems on board (Plotter > fixed GPS/VHF/AIS system > mobile phone > Etrex) . Providing the satellites are working, Etrex gives you Lat and Long, plus heading. Then it's back to paper charts.

Someone at Garmin needs a slap for not just fecking saying which models it does work on right there. I clicked on the "Was this page helpful: Somewhat" option. Even that sounds lacklustre. "Yes/No/Whatever"

Bloody annoying this kind of slap dashery. I was looking for some food storage boxes yesterday and Sainsburys say how many litres but can't be bothered to give the dimensions. Its only essential to know where it will fit in most cases but someone can't be arsed to put the thought and effort in.
 
Managed to have a "chat" with someone at garmin they eventually said , sorry that's not supported by that model, I replied , which model does and they disconnected ??????

This is the new normal people keep referring to. Its been around since the first generation to grow up with computers to do all their thinking and will only get worse. Imagine how thick and useless humans will be when Elon Musk has worked out how to implant google in our brains. He doesn't think it is far off

I think maybe you are asking quite a lot.
There is often sod all space in Newtown Creek, so you will need a tight anchoring zone and an accurate GPS signal.
To get best GPS accuracy, you'd want an external aerial.

Come to that, in Newtown, half the time you'd need an AIS system, to wake you when the other boats are dragging towards you.... :cool:

We find a phone anchor alarm is adequate, but we try to be sensible about what we expect from it.
Go to Newtown on a Tuesday in Winter and pick up a buoy.
 
Not very likely that I will sleep at anchor in my Dabber...
but after reading the thread I checked my GPSMAP64 handheld Garmin.
It does have a "Proximity Alarm" but it works the opposite way round: it rings when it enters the set area, not when it leaves it. The set distance - in nautical miles - has only two decimal figures. Thus the smallest radius checked is 0.01 NM, that is roughly 20 metres. Would this dragging range be small enough?
 
If you have 20m of rode out your minimum circle will be about 30m so yes. Your GPSMap 64 also has an anchor alarm under the marine settings menu.
 
Thank you lustyd!
I found the anchor alarm in the Garmin. There is also a shallow water alarm which could be helpful in the Venice Laguna Velalonga Regatta whose course is partly out of canals on shallow barena.
I wonder where from it can know the depth on the location, may be from the unloaded map?
