This adjustable-speed, electric motor-drive installs easily onto the Focusmate unit, and offers a unique quick disconnect for switching (without tools) between electric and manual operation. Variable-speed, forward/reverse, battery-operated hand-controller is included.

With the exception of the TV-60 (non-"is" version), all current production Tele Vue scopes accept a digital Indicator Kit -- so that their fullest imaging and visual performance can be realized. If a digital Indicator Kit, is installed, measurement is possible to an unprecedented 0.0001" (1/10,000"). A gentle tap on the motor direction switch can produce steps as small as about 0.0005" (5/10,000"). Truly, focusing will be "even better than you imagined."
