I used a Biltmore stick in the Forest Service for tree survey work (we used
diameter tape only on trees we cored for site index). Cheap and fast.
Accurate? Try and compare with diameter tape. You must be looking at the
scale at a 90 degree angle.

Under $100 US in the US.

Dear all

having spent another brambly afternoon on a wet Devon bank failing to
retrieve the loose end of a diameter tape, I’m wondering if there’s an
easier way. Has anyone out there tried using forestry callipers to measure
dbh? If so has anyone got any suggestions as to a useful make? I realise
it’s not as accurate as a diameter tape, but times and places...

Thanks
