WOW! that is exactly what I have been looking for. I like the RX-IV in brush camo. That thing must cost like $1200??? I could use that for my bow and also use it for my long range shooting. I love how it calculates the angle of shot...I have always had to do this manually before adjusting my turrets on scope. Thanks for the link!!! My only concern with this machine is how fast does it wear down the batteries. On a week long trip it may require back-up batteries.
