What "liquid" is inside the compass, and how cold is it rated to (when will it freeze)?

Suunto list the storage and operating temperature range as -30 C to +60 C / -22 F to +140 F . They do not list the liquid used to fill the compass module. They only state, "The compass liquid used by Suunto is specially formulated to provide damping over a large temperature range while preventing the needle from sticking." From my research about different compasses alcohol and kerosene are often used by different companies. See: http://www.suunto.com/da-DK/Support/Compasses-feature-index/ And http://www.suunto.com/en-US/Products/Compasses/Suunto-M-3/Suunto-M-3-IN/?categoryId=5

Boy, you've really got me with this question. I have had mine out in 0 degree temperatures and below and it has never frozen. I'm only guessing, but I would think that it would be some solution containing alcohol or some other chemical that would keep it from freezing. I'm currently use the Silva Ranger compass because it gives me more options such as having a mirror, better for back course/reciprocal headings, etc. and I've never had a Silva, Suunto or Brunton compass freeze and I've used them all in Alaska, Greenland and Iceland.

From the research I did, it will freeze around 22 Fahrenheit. I don't know what liquid is inside.

Yes it is. You can check it by placing it in the freezer for one day and you will notice that it will not freeze entirely. It will be sort of slushy but the liquid that turns into slush is the water; the rest is pure H202.

"Outdoor" is a loose term. I would prevent any water from coming into contact with the unit. However I believe the product would hold up to dust and dirt. Heat may degrade the magnet over time. The cold may not have any affect on it.

It stays pretty cold. If you are worried at all, I would put in one or two small ice packs just for extra chilling.

I have filled mine with a mixture of water, salt, and rubbing alcohol. This way the water can't freeze all of the way and the ice is flexible. After use, I just put it back in the freezer for the next use. The freezing process doesn't seem to hurt the liner of the bag, because it has not leaked at all.

I've used this for years but don't know at what point it will freeze. I think it will freeze, but it will be a little below 32 deg. If you have already purchased Oil Eater, you might put a small amount in a plastic container and place it in a freezer. After it freezes, let it thaw and see if it still performs as advertised.

Liquid. Haven't had any trouble with it yet. I use it on our ice fish house

Never had a problem when the temp. was below 30degs.Lost my last one while ducking hunting, temp was around 30, water temp was cold, ice on surface in areas. I did not dive in after it, ordered another one.

There is not supposed to be any liquid. If the compass is not moving gently tap it on the palm of your hand. If that doesn't free the needle then call the customer care and let them know it is defective.

my daughter uses it cold. It stays cold for about a hour. As for freezing it never got stiff, it always stayed pliable. The ability to strap it on to her body and she can keep moving around with out if falling or leaking it great.

There is no warm or cold. I never heard of it. It just plain light with right spiral blubs. That's all. I swing it and pull forward to me for up reading, when done. I swing it and push backward. It was very cool.

It is a plastic bottle with a metal lid. Specifically a PET (Polyethylene terephthalate). Sounds yucky but that is the common soft drink plastic bottle. I'm from Florida so I can't address the freezing issue...

In the ad it says the clay pack part measures 6'' x 12'' and includes a reusable protective cloth sleeve with a footlong 1 1/2 wide elastic strap with velcro for a secure fit. It gets very cold in the freezer but I wouldn't call it "frozen." It's a oil clay mixture that stays pliable. I'd say somewhere between a half hour and an hour. I have another clay pack and a gel pack that fits in the cloth sleeve, so I can interchange them and always have a cold pack ready. I'd say it weighs about 1 1/2 lbs.

It's a very, verynthick liquid. My only complaint about this product is that it hardens in the cold weather. However, it still breaks down when placed in water.

I've never measured the temp, so I can't say for certain. The Nutropin pen was still cold after a four hour flight.

I live in California so a freeze is not an issue here. also I do not know what the liquid is but it is green. I only use this in side of our small trailer. Works good and easy to see.

I did not take the compass completely out of the packaging because it was a gift but judging by the weight I would assume it's metal. It was heavy for the size. Hope that helps.
