Im very pleased, have to tell someone! Just got Pitch and Roll working on my Trek Transponder. So you can send an SMS to your boat and check out the sea conditions where it is or check if boat is listing. You get 15 pitch and roll numbers (degrees) taken at 1 second intervals. It uses an electronic accelerometer which measures force of gravity and calculates into angles. Looking at the ping below Trek is rolling very slightly but is pitching bow down. I would welcome comments on any better format? Maybe it should also measure "heave" ?

Tony, looks good. Have to say I am very happy with your transponder that I fitted. The original 2G version was good but this one is quicker and more feature packed, but still would have preferred not to have to spend the extra money ( oh how I am over the tellco's).
One of my neighbouring boats got burgled recently, cost him thousands and reaffirmed my decision to install the new one.
Cheers

They were around us recently too so must be in the area.
A liveaboard near me chased a guy off looking at mine. Another near me had some items moved in his cockpit.

Hi, yes there seems to be somewhat regular visiting of this nature. My original purchase of one of these was in response to the theft and damage to my boat a couple of years ago and only the closing down of the 2G network forced me to buy again.
Can honestly say I am not sorry that I have.
Cheers

Well if they do get on your boat Bob you will know straightaway and have a nice photo of them sent to your phone for the police

I wish I had the cams back at the time the ferals stole all the diesel from my boat and left gouge marks on the hull, it would be lovely to identify them.

Level ONE protection against theft (and flooding) could be considered an intelligent sensor with real time Sim-card communication, like Trek's nifty device.

Short of that, what ideas are out there that could provide level TWO protection?

Does anyone have experience of using a 12volt PIR sensor (sold for caravans and sheds) installed inside the boat cabin? It may turn on either a bright flashing deck light or a loud buzzer. Or will a simple window switch on the main hatch provide much the same protection?

We got some great pics of a prick siphoning fuel from our trucks, hose in mouth, can in hand the whole show. Identified him, give it to the cops, guess what ? Not admissible in court ! Cops can only use pics to coerce the f$&@/: to fess up ! Maybe you could incorporate a taser to slow em down till the esteemed constabulary arrive

Hi KArsten,

I have a PIR in the cockpit, connected to a TRek from Tony.
Idea is, as soon as they step in, it activates a solenoid output on the Trek, switching on a siren and strobe, hopefully they bugger off before trying to break in.PIR is just a std home type available from Jaycar and the like.

I keep a cover on the cockpit on the mooring, and only had 1 false alarm when a cormorant got in under the cover.
The system works well, apart from also having to do the 2G to 4G upgrade, plus having to wait for stock.

Thanks Crusty for the very useful info on the PIR. Sounds like birds may set it off, so I'll need to find a way to mount it with a deflector or something, so it sweeps just the cockpit sole and nothing higher.
