I have a Swarovski doubler in excellent shape, I just haven’t use it. This is set up for EL binoculars. $375 TYD. Everything is included that is in the picture.
I’m not sure and I don’t know how to check? I purchased the doubler about three years ago but it does fits my EL binoculars (10x42) which are 15 years old. I assumed they were universal to EL binoculars.
