Anchor text: optical coincident rangefinder
Target Entity: Coincidence_rangefinder
Preceding Context: The British dealt with range measurement first, when it was realised that range was the key to producing a better fuze setting. This led to the Height/Range Finder (HRF), the first model being the Barr & Stroud UB2, a 2-metre
Succeeding Context: mounted on a tripod. It measured the distance to the target and the elevation angle, which together gave the height of the aircraft. These were complex instruments and various other methods were also used. The HRF was soon joined by the Height/Fuze Indicator (HFI), this was marked with elevation angles and height lines overlaid with fuze length curves, using the height reported by the HRF operator, the necessary fuze length could be read off.
