Real life test !
I decided to test my jacket Sunday ....knowing it was armed with a cylinder dated 09/06 and tablet dated Mar29 07 on the side. I knew I had a spare jacket with me for exactly this purpose and in case Matth needed it (again)
Anyhow ..it worked ! I'm not saying it always would and I know the cylinder looked as new.
All of us (well AJ & MattH) commented it took a while to trigger (I'd floated up and took 2-3 secs before it went off) but I don't think is due to age - just the way Halkey Roberts works.
What was most interesting to me was the cold water. Even knowing it would be bloody cold - it took real effort to control my breathing and not jump out.
We all had a go at jumping in except the biggest girly, pansy, skirt wearing, lightweight of a ribnet member (have a guess who - PM me with title 'MattH is a huge huge girl' if you want) who even after lowering himself in couldn't deal with it and jumped straight out again...
Cold water shock...hard work keeping it all together and this was flat calm water and expected....
