Warhammer 40000: Combat Gauge

The perfect tool for quickly and easily measuring the space between models locked in bitter combat, the Combat Gauge has been designed for all those who love to play their games with as little fuss and clutter as possible. 
 
Made from strong yet pliable rubber, with a pristine Imperial eagle design featured on one side, and a more decayed, Chaos-addled design on the other, the Combat Gauge’s four edges measure half an inch, one inch, two inches and three inches incrementally - so should you need to ascertain whether two models are within range for your combat choices, just use the appropriate edge to find out instantly.
