I like my 8x Vortex monocular. For what it is and the price, I think it’d be hard to beat. Additionally, the RRS binocular mount works with it so you can mount it to a tripod with ease.
I got the polymer version of the mount from RRS for $40, they make an aluminum one for $125. But for the monocular (~$135) and mount (~$40), you’ve got a decent setup.
That said, I picked up a used Leupold BT binos with their mil reticle and its definitely easier to use. But FOR THE MONEY, the Vortex is a great deal. Vortex also makes a 15x for a few more hundred.
