Not everyone knows that sometimes when using modern laser technology, old proven solutions come in handy.

Sometimes the operator of the device may forget to remove the protective cap from the gun.

Then the laser will immediately shoot through the cap housing – unfortunately also dirtying the protective glass.

This little ball causes the operator, not seeing the front side of the laser – to quickly realize that the lens cover has not been removed.

Thanks to this small gadget, lasers serve without failure for years. It is certainly worth taking advantage of it!
