RE: Question for Optic Experts...
As someone who works in the optics industry, all I can say is that spend as much money on your binocular as you can afford. If you can't afford good quality optics right now, then save up and buy something better when you CAN afford it.
I live and hunt in the west, and good quality optics are your most important tools. A good quality binocular and spotting scope, along with a good scope will make for a much more enjoyable and successful hunt. You'll be spending the vast majority of your time sitting and glassing. The last thing you need is a binocular or scope that will give you a migrane. Your binocular is your #1 priority. Coues deer hunting is extremely optics intensive. If your using a 10x40 type bino, then you'll absolutely need a spotting scope. Don't forget, a close coues deer shot is250 - 300yards!
As far as "Jason Optics" goes, well I've never come across them. If you have any more detailed questions regarding optics, please just let me know.
