The CRP4 and CRP5 Reflector Poles were developed as a part of AP20 AutoPole solution, a unique smart system that boosts on-site productivity by enabling point measurements with a tilted pole, automatically measuring target heights up to 2.20 m, plus searching and locking to a specific target. The mechanical interface to the AP20 AutoPole ensures precise axis alignment for reliable tilt compensation and stable use in any pole handling, including when the pole is in upside-down use.

The reflector pole can be used with the AP20 sensor and also as a high-class passive pole (without AP20 features), providing the well-known analogue bubble and a printed height scale (metric or feet). The CRP4 and CRP5 are compatible with existing prisms, GNSS antennas and a wide range of Leica Geosystems accessories such as pole clamps, bi-pods, prism adapters, and exchangeable pole tips.
