I would like to figure out how to use the monocular. Can't find instructions anywhere. It has a 4-division reticle inside with each division having 10 divisions. It appears that these may represent angles, with the outside edges being the full 6.2 degrees. But I could be wrong on that.
For a right triangle where the base length is known and a second angle is known, what is the formula for calculating the height. I'd like to figure out how to use the reticle in that monocular. Can't find instructions anywhere. Though I did find a user who spoke very highly of it. http://www.nativetreesociety.org/measure/reticle/monocular_reticle.htm One nifty gizmo. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
