Long Pathlength Option
The standard 4500 MkIII is suitable for installation pathlengths up to 10.6 m
(35 ft).
A special retroreflector allows the 4500 MkIII to be used on installation
pathlengths up to 15 m (50 ft).
The long-pathlength retro is larger than the standard unit and mounts to a
larger standpipe.
The installation is shown below.
