found this on youtube for detecting leaks in an MOD single man liferaft.

Reminds me of
BTW have tried to phone a couple of times but no pickup.

I thought Hydrogen was lighter than air... surely that thing would end up on the ceiling?

So it is, but the weight of the life raft plus the weight of the hydrogen it contains, is greater that the weight of air the life raft displaces, so it stays on the floor.

It is high-tech but I wonder how much more effective than detergent and water? Of course you could go around with a lighted cigarette lighter to detect a leak also.

Thank you SailingSaves!!
I recently bought a 1 ton tray body ute which had previously been used by a company that recycled drums/tanks. Under the passenger seat I found a huge pressure gauge with a foot diameter dial and graduated to a max of 40 psi. I couldn't see a use for it then so contacted the company 3 times asking them to return my call as I was going to return it to them. They didn't return my calls so now the gauge is mine. I figure if I pump up the inflatable and leave the gauge hooked up to it overnight I should be able to see if there has been a pressure drop by morning. (These gauges cost 105 pound sterling!)

Hydrogen is a smaller molecule than Air so may find its way out smaller holes.
You can detect it (with a sensor rather than a match) before you can detect a bubble and soap BUT for most peoples needs a hole that doesn't bubble is probably not user critical.
Your pressure gauge is a good start, but all it tells you is there is a leak. Not where it leaked from. What's more there is a good chance you loose a bit of pressure either due to the fabric its self being partially porous. So you need to know what pressure drop is acceptable over 24hrs...

One of my favourite childhood tv memories, the Clangers - they don't make quality like that any longer; just CGI fighting and stuff.
Shame about the 'phone call; I don't go out much - hardly at all - hence why I a fat bstewrd I guess.
