Tried searching for some user info on this 'scope and got 0 hits. Any user comments on this style scope? I service industrial machines and control systems and thought the battery operated handheld unit would be pretty nice, if its performance is good. The 806 is a 60 MHz unit; I understand that they make 100, 150 and 200 MHz units, as well. Comments from anyone having one of these units would be appreciated.
