This version of an app we made to determine butt end diameter during loading prior to leaving the woods. Designed to reduce incidences of rejection at the scale house. The app also has minor functionality to help determine average dbh, bdft, etc. but again, this is a BETA version, so theres a high probability of error in some of the calculations. If you would like a completed version of the app please contact us at www.catenaut.com Thanks
