Great little prism. I'm a bit more used to the larger square style but an excellent high-quality piece that came in a wonderful little leather carrying case. Great product overall.

Great prism. A very nice prism that came with a soft leather case. I have no problems as far as I see.

Would the 10 work for mature forests in southeastern Indiana, hardwoods?
Yes. A 10-factor prism is a solid choice for mature hardwood stands in southeastern Indiana. The Jim-Gem prism in BAF 10 (Item #59026) is a common all-around setup for Eastern hardwoods and usually gives a manageable count at typical basal areas. With BAF 10, each in tree represents about 10 square feet of basal area per acre. If you find your counts running too high in denser patches, move to BAF 20 to speed things up. If the stand is more open or has smaller stems, BAF 5 will pull in more trees and improve precision.
We have your 10 BAF amber forestry prisms. Are the results following your instructions in square feet per acre or square meters per hectare
Thank you
Bev
