I used the MagView on my elk hunt this year and I have to say it was a joy to use compared to the other options. Light weight and easy to set up and use. Attached is a bull I was after at roughly 2 miles out. The ability to slap the phone on the MagView magnet and use your phones zoom as additional magnification is great for when you are in a hurry to get a photo quick. I would highly recommend this product for anyone who uses optics for long distance viewing. The design is great especially not having to keep up with a case or additional mounting hard wear. My review was based on a backcountry hunt with camp on my back.
