Pro Tips
- Position the lens 10-15cm above the subject for sharpest focus — the optimal focal distance for 3X Fresnel lenses
- Turn on the LED in dim workshop conditions to eliminate shadows when inspecting prong settings or solder joints
- Use the desktop stand mode when checking hallmarks on multiple pieces — keeps both hands free to handle jewelry
- Wipe the lens with a microfiber cloth before use — fingerprints on a Fresnel lens cause significant image distortion
- For sewing and embroidery, hang the magnifier from the neck strap at chest height to keep both hands on the fabric
Frequently Asked Questions
Q: Is 3X magnification enough for jewelry inspection?
A: Yes for general inspection — hallmark reading, prong checking and solder joint review. For gemological grading or detecting inclusions in stones, a 10X loupe or microscope is recommended instead.
Q: Does it work without the LED light?
A: Yes. The LED can be switched off and the magnifier works in any well-lit environment. The LED is most useful in dim conditions or for shadow-free close inspection.
Q: What batteries does it use?
A: 2 x AAA batteries, not included. Standard alkaline batteries are recommended for consistent LED brightness.
Q: Can it be used as a desktop stand without the neck strap?
A: Yes. The magnifier folds into a stable desktop stand position independently of the neck strap.
Q: How do I clean the lens?
A: Wipe gently with a soft microfiber cloth. Avoid paper towels or abrasive materials that may scratch the Fresnel surface.
Q: Is this suitable for low vision or elderly users?
A: Yes. The large 290 x 200mm viewing area and hands-free modes make it practical for users who need extended magnification for reading, crafts or detailed work.
