New here so I apologize if I ramble. I hunt a lot of spot and stalk for white tails in pretty open country. I have a pair of Nikon 12x42 monarchs and I really like them but both of my boys and I drew buck tags this year so I want to add another pair of binoculars. I would like to keep my budget around $500 but if I have to spend a couple hundred more to get better optics I will. Given the type of hunting I do I think I want to go to 15-18 power and the choices I am considering right now are the vortex diamondbacks or vultures or the leupold bx5. Unfortunately nobody locally carries any of them to try. Any advice or insight would be much appreciated. Thank you.
