Here's a couple of options, I use a Nuuk bag from water shed, 200ft depth rating and I can put fire starting equipment, ACR PLB, GPS,radio,compass and odds and ends. It's relativity small, durable, and you can release the pressure like a zip lock bag when sealing and has a lifetime warranty. Money well spent. As for fire equipment I use a light my fire army ferirod,Magnesium block, 2 country comm SS peanut lighters with fov with lighter fluid, and a mini zippo. Life boat matches is good to have as well (I need to add those to my kit as well and is a good suggestion from Chris). Also have cotton balls with petroleum jelly. The kit goes in my BOB kit when not diving and transfers to the belt when diving. I haven't had any luck with vacuum sealing bags or zip lock bags at depth.

YoDuh needs to dive in Hawaii, see lava flow into ocean at night.

I'd think a sparklight, a minibic with the plunger wedged, and a lot of tinder (cotton balls, tinder quiks, or coglahns fiber-based firestarters) in Witz case, which you then seal with GOOD tape, and then vacuum pack, and vacuum pack again.

Just paint the fire steel with finger nail polish, its enamel so it dries quick and if the color bothers you, use clear. Do the same thing to the steel striker.

It’s enamel paint, should hold up well. And it comes in purdy colors…

that is why you vacuum seal your kit then put it in an otter box.

I’m not sure what the original posters intention is, other then to have a way to start a fire after everything being wet. (is it for a single use or did he want something he can use more then one time before he’s back home?)

But I would guess that vacuum sealing is a home operation only.

How repeatable is vacuum sealing in the field? My guess not too much. A fire steel and some nail polish are very repeatable. As are the wax cardboard and matches I posted above, or some kind of watertight container. But I would always worry about a container getting some water in it. Something about a guy named Murphy.

I have no connection with the company. I bought one, but have not tested it. A friend is taking mine elk hunting in the Bitterroots next month.

It looks solid, with a sturdy o-ring seal. I might add some lock-tite or some kind sealer just to make sure there is no leakage through the screw hole that hold the blade to the aluminum case.

Cotton balls with Petrolium Jelly make a waterproof tinder. When I demonstrate fire making, I soak a CB/PJ in water. Remove it from the water, shake the water off and light. Burns great, but watch for the remaining water drops to "explode" with hot bits of CB/PJ and boiling water. Never tried it after taking the CB/PJ to any real depth of water though. Give it a try and report results please.

I like the idea of using a bag sealer and sealing a Striker and Tinder. Make sure that when you test it you go below 100' so that it gets fully compacted by being exposed to 4 Atmospheres. this way hen you open it (after you get to shore) you can ensure it will function. Try a few kinds of tinder and see which light better after compaction. Wetfire should be unaffected, but since I never carried any firelighting gear when I was a scuba instructor I am just guessing.

Neat idea by the way, hope you test programme goes well.
