Which vortex

[Maverick]

Sounds like the 80mm would better suite me then because a lot of the glassing I do for in the off season is at first and last light. I'd like to pack it around for shed season but I think I can do that with the 80mm to though. Little bit more wight but I think will be worth. I want a straight not an angled.

Just noticed you are looking at the Diamondback line.  I would def go with the 80mm in that line.  It will buy you a lot more in that line.

Just an FYI but Cameraland has the Vortex Viper non HD discounted to $499 which is the same price as the Diamondback but a little better class of glass.

Not to sound like an idiot but what is the difference in hd and non hd

Not to sound like an idiot but what is the difference in hd and non hd

someone else will know more than I but I think it is high density glass or high density coatings on the glass.
I think it means more clarity and color contrast... and more $.

Yes, the 80mm will entertain much more light over the 60mm. The 80mm weighs in at 2lb 15oz. It is bigger & a little heavier but it will do better during all lower light conditions. The DiamondBack 60mm & 80mm are non HD models, the 80 runs aprox 450.00 -  The photo is of the 80mm.

  HD glass is recommended if hunters plan on doing much digiscoping, this is because you have a clearer & more colorful picture just as your TV is much better with HD than non HD! Colors & clarity will "pop" much nicer!
