Looks like they put the button you push to range something on the Left side which is good for right handed bowhunters. Also the minimum "range" is now a little over 5 yards instead of 22 yards as on the old model. These are two improvements I'm sure they made with bowhunters in mind.
As a right handed bowhunter I would want the button on the RIGHT side as I hold my bow with my left hand. The button side has NOT changed from the old EL ranges. The minimum distance of 5 yards is the only plus I see on these.
