I like the idea of them alot. I bought a pair of geovids a few years ago and I am left eye dominant and it was a weird deal using them I got a kind of double image on the reticle. I traded them to my boss for a pair of el's. A few other guys I hunt with use them and love them. I want to check out the el range and see if it will work for a lefty (if someone has a pair and wants to hold them upside down to switch eyes and let me know it would be awesome) I just wish they ranged closer but it isn't a huge deal. I can't really see a downside from hunting with the guys that have them, less to carry, always close, easier to hold steady, less to lose, (sounds stupid but I have gone on some long hikes to retrieve my rangefinder lol)
