Returned to the first series scopes from factory where they repaired. After they have tested.
For 10 Celsius cooled, and then the day we left to warm up to 40 Celsius. The paralax displaced 2 mm on the side wheel, so practically flawless. Tell those who has last year S & B FT, send it back for repair, because the experience they found that what was wrong.
With our my mates we have bought 5 in 2010, their funds are good.
