For the past few years I have been coveting a pair of Zeiss 8x30 Conquest Binoculars but coudn't decide which child I would need send off to work in order to finance. Long story short I am now looking at used ones on Ebay as they have been discontinued.
Question, what is the difference between BT and T versions?
Thanks in advance for any responses.

I am familiar with some of the Zeiss models, and the Conquest
models are similar without any changes along the way.

I am thinking that the ads you are looking at, are just how
the seller is describing them.

I would consider them the same.

thank you
