Hi Cam , I have a pair of Zhumell 25x100 binos and mate they are awsome !!
.
But ,, there is always a BUT , so here it is ....
.
They are BIG and HEAVY ! they are not hand held at all so need a heavy duty mount to see all they can show at there best , and bieleve me they show a lot when they are mounted steadily .
I would go for the 5 inch scope as that already comes with a nount and then later on get those awsome 100mm binos .
Here is a photo of mine , mounted .
I made the adaptor that fits the binos to mount and the dew shield my self , so they are one of a kind .
Brian.
