View Full Version : Compass problem
Here's one I haven't seen before:
I have 2 Suunto RA-69s. I've had them for some years... One of them is fine, but on the other, the liquid in the capsule has turned blue/green and cloudy, making the thing all but unusable. There is no apparent damage to the capsule.
Has anyone else come across this before? And knows what has caused it?
Compass liquid is actually a light oil according to my information. That should rule out any algae bloom. I would contact Suunto. If nothing else, you have a good example for redundancy.
I think I might give them a prod. I don't think they make the RA69 any more, however. The blue/green looks less like an algal bloom in colour and more like a copper salt - but I can't see any evidence of copper or brass inside the capsule.
Sounds like corrosion to me. I think that the bearing might be brass actually.
We have a suunto at my TA troop and thats gone green/blue
When I saw it I stupidly thought it was some sort of special type that glowed in the dark
I was wrong :oops:
Now I'm using a *spit* MS browser, I can use the Suunto page. Funnily enough, this was in the FAQ, typos and all:
What is the reason for liquide inside the compass to become colored?
In 1980 manufactured compasses Suunto used a certain metall in needle hubs which smelted partly to the liquide. This caused liquide to become colored. This does not affect to the accuracy of your compass.
Might not affect the accuracy, but I can't read the ruddy thing!
