Hi, I have been an Optician since 1988 and have only ever used the Marco 101 and the B&L Vertometer and hands down the Marco with the prism compensater is the best. I’m teaching my 24 year old son and your video has been very helpful! Thank you!
@@adamhoward3627 That’s great to hear and thank you for sharing. There’s a few other videos in this series also that can help your son further his understanding.
First time Marco user; I have one where the mires are off when the prism device is set at 0. They are @ .5d be and .5d bo (if it were a right eye.) How do I adjust the mires back to zero?
For a quick solution, try adjusting the PCD (Prism Compensation Device), located just behind the marking pins. As you turn the metal knob you'll see the target move inside the reticle. It will be tricky at first, but with a little patience you should be able to align your target back to perfect center. This is only a temporary solution, especially depending on how much it's off. If it's just a little bit it may have just been move accidentally; but if it's off by a lot then get it recalibrated because it will make spotting lenses with prism much more difficult. Thanks for watching! :)
The very front of the lensmeter flip open (the end opposite to the eyepiece), just pull the top down and the bulb will come out. Here's a link where we order replacement bulbs from called Hilco: www.hilcovision.com/f/LENS-METER-BULB-4007-110V-25W-FOR-MARCO-101

How do you change the bulb?
