Product Information
Full details
The UST Hi Vis Folding Map Compass is an essential navigation tool for hikers, backpackers, and orienteering enthusiasts who require a reliable way to plot routes in remote environments. It offers the benefit of a high-contrast fluorescent base plate and a built-in sighting mirror for precise bearing calculation; however, users should note that the compact size, while portable, requires steady hands for accurate reading compared to larger baseplate compasses.

FAQs
Is the UST Folding Map Compass waterproof?
The housing is water-resistant, protecting the liquid-filled compass from rain and splashes, though it should not be submerged for extended periods.
Does it come with a declination tool?
Yes, a dedicated screwdriver is included with the compass specifically for making declination adjustments.
What are the dimensions of the compass?
The unit measures 3.7 by 2.5 by 0.7 inches.
Can this be used for 1:50,000 scale maps?
While it features 1:25,000 scales, you can still use it on 1:50,000 maps by doubling your measurements or using the inch/metric rulers to convert distance.
Why is there a bubble in the liquid?
Small bubbles can sometimes appear in liquid-filled compasses due to extreme temperature or altitude changes. This is normal and usually does not affect performance unless the bubble is large enough to pin the needle.
Troubleshooting
Compass needle is slow to stabilize
Hold the compass perfectly level; if it still struggles, the liquid housing may have a bubble or a severe magnetic interference is nearby.
Difficulty reading bearing in bright sun
The fluorescent base is designed for low light; in direct, harsh sunlight, place the compass in the shadow of your body to reduce glare on the plastic.

Setup, Compatibility & Care
Before heading out, ensure you calibrate the compass to your specific location. Use the provided screwdriver to adjust the declination to match the magnetic variation of the region you are visiting. To maintain the device, avoid exposing the compass to strong magnetic fields, such as those generated by cell phones, power lines, or metal tools, as these can cause permanent inaccuracy in the magnetic needle. When not in use, always keep the folding case closed to prevent debris from damaging the bezel. Clean the surface with a soft, damp cloth and avoid using harsh chemicals or solvents that could cloud the plastic cover.
