[MARMAM] binoculars with integrated compass and laser rangefinder

Dear MARMAMers, For several years we have been collecting data on the movements of fin and sperm whales in the PELAGOS Sanctuary. During our data collection the position of the whale is taken with its bearing and distance from our sailing boat (observer usually between 3 and 5m above the sea surface) using binoculars with an integrated compass and reticle scale. However, hoping to increase the accuracy of our distance measurements we were wandering if anyone has heard of or is using binoculars with integrated compass and laser rangefinder all in one, and if they have some feedback on these. Thank you very much. Jerome Couvat Project Manager at Souffleurs d'Ecume jerome.couvat@souffleursdecume.com
