Product Details

WTTC with water polo

The wireless tabletop controller features an operating distance up to 1,000 ft., buttons with tactile dome feedback, and a large transflective LCD screen that is easily readable in all environments from darkness to bright sunlight. The controller includes a built-in real time clock to keep time of day.

Slide-in keyboard inserts and additional software packages allow you to run multiple sports on your scoreboard with the same controller, or operate multiple scoreboards with one controller. Configurable defaults allow customizing to your league rules including alternate shot/play clock times. The controller supports the external Run/Stop/Reset unit to allow for additional clock operators.  The Run/Stop/Reset units are optional accessories for the wireless tabletop controller.  They allow a second or third operator to assist in controlling game time and shot time for water polo, basketball, hockey, and lacrosse.  For football, they allow the additional operators to assist in controlling game time and play clock time.
