If you are experiencing problems with a handheld unit, please take a look below for frequently asked questions.
Laser does not power on:
Make sure battery is the proper model, voltage and current rating as specified on laser purchase page. (ex. Saft brand batteries are known to be weak)
Clean driver contact pad. (positive battery PCB connection may still have residue from factory)
Bypass tail switch using a metal object. (jumping battery negative directly to host). If the laser powers on, the switch is faulty. Contact us for a free replacement.
Test battery voltage with a voltmeter. (should read between 3.8v-4.2v).
If the battery has been inserted backwards, the driver may be damaged. Send us a message for a repair.
Laser weak output:
Make sure battery is the proper model, voltage and current rating as specified on laser purchase page. (ex. Saft brand batteries are known to be weak)
Test battery voltage with a voltmeter (should read between 3.8v-4.2v)
If battery is from a reputable seller, and of correct voltage/current rating and the laser is still a dim output, the laser likely requires repair.
Laser flashing:
A flashing/blinking laser could mean a low battery voltage. Test with a new, freshly charged battery.
A flashing/blinking laser could mean driver over-temp condition. Let the unit cool down before use.
Bad laser beam:
REMOVE THE BATTERY BEFORE ATTEMPTING ANY ADJUSTMENT!
Turning the lens does not change focus; remove the knurled thumb screw completely, then remove the lens. Screw both together, then reinstall lens components in reverse.
A large circular beam; may mean the lens is simply out of focus. It can be manually adjusted by twisting the front thumb screw. Be gentle to avoid damage .
A strange wave pattern means the acrylic lens has melted. The lens will need replacement. Avoid burning up close and always keep the lens clean.
A spotted laser beam; with artifacts may mean the lens is dirty or has been damaged. Clean the lens gently with a clean cotton swab and isopropyl alcohol.
A line instead of a dot; may be normal. Some of our products use multi-mode diodes which have large "divergence" at long distances.
