Rock Clock Installation Guide

Rock Clock™ is a premiere curling timer developed by GEOMA (by curlers, for curlers). Designed for competitive curling events, the development and testing of Rock Clock involved the input from curlers, coaches and officials. Rock Clock runs on any computer with the Windows XP or newer operating system and has full output capabilities to any display source.

Volunteers at competitive curling events found that Rock Clock is simple, easy to use and have provided positive feedback. The one-touch keyboard commands control all aspects of the application. Minimal set-up and training is required, making Rock Clock an application any volunteer can be using in less than five minutes.

Rock Clock features all the timing functions required during a competitive curling game. Time outs, breaks between ends, practice time, 5th end breaks and the game clock are all preset to Ontario curling regulations and are customizable to meet timing requirements for other regions. The game clock is easily adjusted during play without restarting the program. Rock colours are chosen from the start screen to match your club’s rocks, reducing on-ice confusion during curling games.

We have staff available for training and set-up if required.
