Height-accumulation data were collected using the Spiegel Relaskop and the Wheeler Pentaprism. Mean tree volumes calculated for the instruments mounted on a tripod were not significantly different. When the instruments were held by hand, however, mean Pentaprism and mean Relaskop volumes differed significantly. Mean volumes for tripod-mounted and hand-held Relaskops differed significantly as well. Volumes of individual trees varied widely with the different instrument-support combinations. Time was saved with the Relaskop.
