In my earlier post I was referring to my 2002 TBolt not matching the performance of my 2201 or HP Z3801A rec. I am sorry to rehash an old discussions, does anyone have a link that details TBolt evolution. I am familiar with the mid 2001 change from the Piezo to Trimble oscillator, but I do not know much about the timeline of more recent changes. thanks
