I havn't seen an mention of this, so I am assumeing you still need an ADI, or cosine and have the ability to in put angle to shot and the unit will give the shoot to range? That being said would a person be better off going with Gunworks G7 range finder. The reason I am asking I am about to purchase a leica 1600B at $800. and then another $600 for the Kestrel, for a total of $1400. you can spend another $200 and get a unit that will pretty much do it all and have even less to carry around every time you go shot or hunt. Any thoughts?
