GrumpyTim | Sekonic Marine Meter II - Waterproof Exposure Meter @GrumpyTim | Uploaded 9 months ago | Updated 2 hours ago
In this video we'll take a look at a Sekonic Marine Meter II, model No. L-164C (or at least I think that's the correct model number). The Marine Meter is a waterproof exposure meter, or light meter if you prefer, designed specifically for underwater photography, although it will work perfectly well above the water too. My version of the meter was probably made in the 80s or 90s, but finding out exact information about these meters is a bit difficult - there's no references to them in any of my old camera magazines.
When I first uploaded this video, a regular viewer pointed out that the zinc air cells can produce quite a bit of gas (Hydrogen), which could potentially cause a problem if they were sealed inside the casing of the meter (I've since added a section to the video and re-uploaded it) - I suspect once the pressure had built up, the big seal round the front glass (plastic) would move slightly and let the pressure escape (that seal being designed to withstand inward water pressure not a build up of gas from inside the unit), but it would probably be wise to remove the battery from this meter after use, or, if you're not using it for diving, leave the "O" ring out when you fit the battery hatch. I'll put a link to one of Big Clive's videos below, where he does some experiments with zinc air batteries and the gas they produce.
