    Silva Compass Bubbles

    Recently, all three of my Silva compasses have developed small air bubbles, effectively simultaneously. They range in age from about 10 years to a couple of years old. They've been kept in rucksacks and bumbags hanging in my garage, which doesn't get particularly cold or hot, so I'm a bit flummoxed (and peed off) as to why this has happened. They're still usable for now, but if the bubbles get worse (and I've no idea what caused the air to enter the needle housing) there's the expense of replacement. We'll see.

    Does anyone else have experience of this? Quick internet search doesn't suggest any real remedies either.

    I have one that I bought 4 years ago, which developed a bubble this year. Still works OK (but it hasn't had much use this year).

    My Silva compass also developed a large bubble this year, and i eventually had to get rid... although i must have had it for over decade.

    Replaced it with..... another Silva

    Geezzz! That proves it. There's definitely something massively sinister going on here, while the World has been preoccupied with COVID.

    I like the last link especially.

    So, if the bubble gets bigger or smaller depending on altitude, with the use of a micrometer and a set of logarithmic tables or slide rule, you could use it out on the mountain side as a makeshift altimeter - cool (to avoid any misconstruing, I'm only joking!).

    One compass resting and warming on the Aga top now, we'll see if we can bash a bubble...

    Iíve just checked on my compass collection (3 Silva, 1 Moscow) and they are bubble-free.
    Iím surprised as the Silvas are 10, 35 and 45ish years old, dating back to my ML, my first cub hike and my Dadís ML respectively. They all work absolutely fine. Just a little corrosion on the 35yo Silva Starter needle South.
    The Moscow is a thumb compass and a thing of beauty, especially as it also a SI dibber. (No bubbles there neither).

    Thanks for the feedback Felltrumpet and glad to hear yours are fine. Yes, mine are of various ages too, and I was just surprised they all seem to develop a bubble together. I'm thinking it was something to do with the garage environment they were stored in, perhaps. I also have one kept in my office that's fine. Fortunately the bubbles aren't large and if they do become a problem I'll have a ready excuse to buy a brand new Silva

    Why not? One just can't have too many compasses.
