Anyone have any experience with the bushnell conx 1 mile rangefinder? Haven't found any bad reviews and it looks like there are lots of capabilities that I could really confuse myself with. Like linking it to a phone app, linking to a kestrel and etc. Seems like something I wouldn't outgrow. Plus, they can be had for around $300 which I can't figure why the pricing is so up and down between stores. They are everywhere between $299 and $799 for the same one. Thanks for any input
