The Vic-Tic,
manufactured by the Victoreen Instrument Co., was primarily intended for
use where a heavy rugged instrument was not needed. Victoreen described
its application as follows: "For vacation and part time prospecting,
school science class." The
detector was an aluminum walled GM tube (1B85) housed inside the gold
colored case. It had two distinguishing features. First, it was
small (6.5" x 4.5" x
3.5") and light (3 pounds).
Second, it employed a transistor-amplified speaker (rather than
headphones). Three accessories were
available for the Vic-Tic: an external hand-held GM probe that was plugged
into a jack on the front of the case, a "deep hole probe" with
100 feet of cable, and what Victoreen referred to as
the “Bismuth Six Pack,” an assembly of six bismuth screened GM tubes
that could be fastened to the bottom of the meter case.
