Thanks luckynv. I've been to wyoming once with my leupold mojave binos and they are ok. I'm going again this year and considering an upgrade. I'm not sure if I should just bite the bullet and go with conquest hd's or settle for the terras or look at zen ray or use my leupolds. I know I can do better than the leupolds for not much more money. I least I think i can.Not sure how to measure eye strain but here goes, I used them extensively last season for periods of up to two hours at a time and did not notice any eyestrain. I noticed eyestrain in the past after about 10 minutes with my cheap nikons. By cheap I mean less than $100.00. I am not sure that they are better than your Leupolds as I have only looked through those inside of a store. The Leupold Mojave is a decent low-mid range priced binoc. The only way to really know if you should sell yours and go with the Terra is a side by side comparison in decent conditions. Hard to do with artificial light inside a store with a salesman eyeing you. Hope that helps a little. Good luck and God bless
no apologies needed that is good infoI apologize to whoever started this thread for all the extra stuff I brought into it. I realize three of the binos I discussed are not in the same class/price range as the original Terra thread topic. Just thougth I'd share my observations.
