Abstract
Two commercial laser dendrometers were tested under controlled and fie ld conditions, and contrasted with alternative instruments. Testing fo cused on height measurement, but also considered distance and remote d iameter measurements. Both laser instruments gave very precise estimat es, but showed some bias. Users of these and other 'high-tech' instrum ents are reminded that precision is not synonymous with accuracy. User s should not become complacent about the submillimetre readout, but sh ould calibrate instruments to examine if users' accuracy requirements are satisfied. Instruments may need to be re-calibrated each measureme nt season and after any mishandling.
