Baader Laser Collimation Mark III Issue?
I just bought a Baader Laser Collimation Mark III.
After a few minutes of use, the laser fades until no laser light is visible.
I then turn off the collimator off and leave it for a while.
Turning it back on, the laser starts working for a short before fading away again.
I have replaced the batteries, but it did not change the behaviour.
Any suggestion?
Thanks
Brendan
