NavList:

Dear list Members,

 

Here is a sample of backlash measurements done with my 76 SNO-T at 0? altitude sighting a not so distant power line.The instrument, although clean, could have been regularly used when in service with the Soviet Navy and therefore I would not be surprised if some wear had developped in the gears
I guess part of the results spread is due to the operator ageing eyes.
