Fujinon Mariner WPC-XL Binocular - Answered Questions & Fixed issues

It'll depend a bit on the root of the problem.
You can get double vision from properly aligned binoculars if the optics are too far apart or too close, relative to the spacing of your eyes. you'll need to bend them at the central hinge to make sure that both eyes are centered on the input lenses.

If you're still getting the migraine-inducing double image, they probably got dropped at some point. This can be a wide range of difficulty to fix. Here's what I've done in some past cases with flea market binocs that I bought cheap due to the skewed alignment.

For many binocs, the upper (eyeball end) and/or lower (field end) are screwed to the central body of the binocs, where all the folding optics are to widen the lenses from your eye spacing. If they have been dropped, (or disassembled and put back together sloppy), then they may be cockeyed at one of these joins. Look at each seam to the central body and see if any of them have a gap, especially one that is larger on one side than another. You can then apply firm un-screwing twist and see if it will unscrew. if it will, and before you unscrew it all the way, wash your hands and clear a clean surface to work on. Unscrew the segment, inspect the threads for crud that might have got in while cockeyed. Then visually square up the component and gently screw it back in. if it was mis-assembled, the threads may be a bit gummed, and you'll have to be patient to keep the optic square, and back off and start again if it tries to drag over to cockeyed threading. Once it's square, gently working the thread back into place by turning back and forth a half turn back, 3/4 forward, half back, 3/4 forward, can help the thread recuperate. Eventually, it should screw all the way in, firmly, and be square. No more double vision.

For some models, like my Nikon fixed pocket binocs, there's no zoom and just a focus knob. On my brothers pair, it got cockeyed. In that case, I gently unscrewed the locking rings for the glass on the eyeball side. One of them was loose and the lens was a bit cockeyed. In that case, I removed, it (wearing nitrile gloves), cleaned it with eyeglasses cleaning solution and a microfiber cloth, put it back in, screwed the ring in firmly,and it was good to go.

Bottom line, if you have some basic DIY skills, unscrewing the entry optics, or the optics sections, isn't too big a deal. Just be mindful not to let dust (or worse) get inside while you have things open. You can get a lot of fix just from that much.

Good Luck!

The reflectors are out of alignment; the binoculars have been dropped. You may want to contact the manufactired to see about getting realignement.

Your binoculars may be out of collimation. With binoculars, it's essential that the two optical systems be precisely aligned. Unfortunately, these binoculars are very cheaply made, and are easily knocked out of alignment, even during normal shipping. There are instructions online for collimating binoculars.

Hope helps.

How to use the reticle:
The vertical scale (reticle) visible through the left half of the binocular, above the compass display, allows you to calculate distance to an object if you know its height, or to calculate the height of an object if you know its distance from you.
Each mark on the vertical scale has a value of 5 MIL (1Mil is equivalent to an angel that can determined an object one meter in height at a distance of 1000 meters). Therefore, if a navigation chart gives the height of an object, by sighting on it and counting the number of MILS, you can determine how far away it is.
To Measuer distance when height is known:
Object Height(m)/Scale Reading x 1000m=Distance in Meters
To Measure height when distance is known:
Distance(m)xScale Reading/1000=Object height in meters

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. Here is their site:
Good luck, and hope this helps.

Why did you post this on the TELESCOPE topic?

Fuji Optics | Answered on Aug 31, 2010 | 39 views

Hamimex are Japanese made binoculars. If you are wondering how good as far as resale. They wont get much maybe twenty dollars if you are lucky on the auction site. They are not really a collectable except to someone who specialises in japanese binoculars. If you are wondering how good in comparison to others. They are on par with all the other cheaply made japanese binoculars. If they work and you enjoy using them than thats all that matters. Great leaps in price don't necessarily mean great leaps in optical quality. To get a much noticeable better view than the Hanimex would require a large leap in price.

Sorry, my ESP is switched off.

If you give no details of the optical equipment, how do you expect anyone to be able to answer ?

Optics | Answered on Jul 06, 2019 | 24 views

Try the manufacturer, original seller or Ebay

On what equipment ?
If it is a bicycle, 1973
If it is a motor mower or washing machine, 1982
If it is a camcorder or fishing reel, either 1997 or 2008, or some date in between.

Of course, be my guest. Fixya does not supply such documentation, so you will have to source it elsewhere.

I also have a Tasco telescope model 49060700 and I could not figure out for the life of me how to replace the battery in the finderscope. After Googling it and then finally getting frustrated and taking it apart I found the battery! Then I found out of course I did need to take it apart! As you can see by the picture on the side of the finderscope you see where it says PUSH. On the other side it says BATTERY. Now when you're looking and feeling of this on the scope you cannot tell that it's not part of the design on the plastic. I'm thinking push what? Well when I tore into its all the location of the battery then I figured it out. I put pressure on where it says push and the little battery compartment started to slide out toward the other side of the scope. I use the little enclosed screwdriver to use pressure to push it on through. I hope this helps anyone who searches for how to replace the battery. Maybe it was obvious to some people but it wasn't obvious to me! It is a lithium CR2032 3 volt battery.
