Sea Marshall AU9-WF tech query

[Kernow Buoy]

So my Sea Marshall arrived today and very pleased with it I am too. Had a good look through the online manual but still have an unanswered query, just WTF is it? :-)

S'mine I tell you, err..... an MOB thingy, so that big searchlight thing over my house isn't the moon?

is kind of like an epirb / plb but for localised use by boats equiped with suitable direction finding kit.

a lot of the windfarms insist all workboats have the DF kit, and all workers the Sea Marshal unit

you havent paid money for that have you??
Its a 121.5MHz plb ..the system ceased to be monitored several years ago. Only used as a near-to homing device now.
We have them on the big boat for techies and a base set on the boat to track an activated unit..allegedly. Loadsa false alarms. Very short range ...we have tested them by activating in harbour, with CG permission although as they dont monitor it they were disinterested, and the range to our base station was a matter of yards, perhaps 100 for a good one.
No good for use in a boat except one equipped with a base unit...and even then all our techs are now on proper 406 plbs which also do send 121.5 but only for short range homing in. Theres a rack of sea marshalls onboard the boat obsolete and gently ageing down in the accomodation.

Hi Dave
Thanks for that, makes sense that there was little mention of them on the net and none on here!
Happily no money changed hands they (3) were attached to some Baltic LJ's on fleabay. I'd sort of understood there was a base unit required but wondered if they were still useful as PLB's on their own or if they could be adapted, would seem not, thanks for the info

No probs

Some of the oil industry vessels here had this fitted for working with the company that I used to work with a couple of years back, people had to carry the personal unit and there was a base unit on board each PSV.

As a follow up to this thread Janet in Admin had an email from Michelle Tait in SeaMarshall sales support who asked to contact me in case I was trying to use this unit as a stand alone PLB/EPIRB, have to say I'm impressed with that can't think a 2nd hand purchase off ebay would have brought attention from many companies, good on them

Word of your amazing boating "adventures" is obviously getting around. Nice one K.
