Steiner Commander Compass not working - possibly low of fluid?
I have a pair of Steiner 7x50 Military Marine, Commander Pilot binoculars with a compass on top. The compass moves a little but does not change as one turns around. I can see a "water line" in the display in the right lens when i tip the binoculars up and down - not sure if this is the problem.
Does anybody know anything about what it takes to open these up and see what is wrong? Or does anybody know what fluid is inside the compass? It would be nice to have this ready ahead of time i figure.
I also need a set of caps (all 4) if anybody has a idea how to find these or know of suitable replacement caps I would love to hear.
Thanks for any info!

Open the battery door, clean all inside with Alcohol & Q-tip. Check that the AG10 or 389 batteries are positive up. Now the compass dial pivots on a shaft. It seems to get caught. Take a strong magnet and rotate it above the compass lying horizontal and spin it until it spins freely. Take it away slowly. Does the compass settle down to accurate heading? If so place back in the top of the model 322BCW observing the glued in marks on the clear window area. Re-screw in, press brass button red LED should light.. If NOT recheck for corrosion.

I've been thinking about this for awhile, and it seems to me you're experiencing a factory defect. I don't have one of these devices, or I'd know what "normal" was for compass, but if you can't easily have the display centered, something is out of kilter. Was it always like this, or did it just start occurring recenty? Your best venue would be to contact Fujinon support and see if they will replace or fix the problem.

Good luck, and hope this helps.
I think you mean the two sides are not quite pointing in the same direction. This is called collimation, as in "the collimation is out". Alignment would be the everyday word. In binoculars, collimation faults are usually the result of a knock causing one of the prisms to shift slightly. It can be simple to put right, for a skilled person who knows what he is doing, if adjustments are available. Or the binoculars may need disassembly and an optical bench. I imagine that you would be able to replace these more cheaply than fix them, unless they are very high quality or collectable. I have made a mess of a few pair, and had a few successes, always with binocs that were uneconomic to have repaired professionally.
I would contact Steiner. The Commander has a 30 year warranty. Unless there has been some damage caused by you it shouldn;t have leaked. To remove the compass would compromise the seal between it and the body. The body is nitrogen filled and the gas will escape. It's not a home repair job and needs to be sent to the company.
To get your year of manufacture look between both barrels at the front. The disc on the hinge pin will have a number. If it is a ten digit number. The first and third digits will give the year eg: 908245 etc is 98 or 1998.
If it is a five or seven digit number then it is the first two numbers eg 97123 is 97 or 1997.
You can get the green eyecups for the military marine model from steinerpartsdirect.com I can also recommend changing the standard neck strap with a neoprene one for an older Steiner Nighthunter that is non cliclock. Makes for a much more confortable carry. Just make sure it is one that loops and isn't click lock.
The model of Steiner binoculars is on the plastic plates on the body. On earlier models mainly the green rubber covered military types is is molded at the front of the body near the objective lenses. These were called the Military/Marine and are of a different specification to the current Military/Marine. The original were a military bincocular which has more in common with the current Steiner Military. If you are after the serial number it is located on the front metal disc between the binocular barrels on a porro prism binocular. A porro is where the objective lenses are spaced further apart than the eyepieces. On a roof prism Steiner the serial number is located underneath between the two barrels on the hinge. Roof prisms are binoculars where the objective and the eyepieces are in line. If the serial number is a 10 digit number the 1st and 3rd numbers will give you the year of manufacture.
EG: 9042577777= 1994
If it is five or six digit number then it is the 1st and 2nd numbers
EG: 871245= 1987
You are correct that the lines are for rangefinding. This is what is called a reticle. Without seeing how they are set up it is hard to determine the scale used. Most scales are in meters, some in yards, but they all work the same. Go to any of the following websites and download the instruction manual.
Go to Tasco and search for the Offshore OS 36 or 54 manual. OR go to Steiner Optic and download the manual for the Military 7x50 or Commander or Navigator models.
These instruction manuals have details and diagrams of how to read a rangefinder reticle.
Basically if you know the distance to an object you can estimate its height or size. OR if you know the size of an object you can estimate the distance to the object.
Its easier to explain seeing a diagram. Go to Tascos website and download the instruction manual for the Offshore binoculars or Steiner Optic website and download the general binoculars instruction manual. It has all of Steiners models incuding those with a reticle. Most reticles are the same and there is no difference between meters and yards as your calculations are an approximate.
If your Fujinon is an ex military unit it has what is known as an M22 reticle. It is only slighlty different as it is graduated in mils but the calculations is the same. If it is the M22, google Binocular M22 manual. The military number for this is TM 9-1240-403-12 & P
