Wow. I should try that. Thanks!
Gosky makes a 20-60x80 that connects to a mobile device. I do not have one of my own. A friend of mine in the north woods of Wisconsin has one and he claims to spot 7mm mag holes in targets at 650 yds on his iPad. His range is not as long as mine but he swears he could see them, his guess, at 900. They do come in pretty handy. And relatively cheap. Sure saves a lot of four wheeler rides to the targets!!!
