You can use basemap with bluetooth rangefinders using your phones compass like in Jasnts video. The latest Sigs use the compass in the rangefinder instead for a more seamless solution. BUT apparently the built-in compass in the Sig is not so great so either way so its still early tech.
The Sig 10k is their Binoculars. Wish they weren't so clunky looking. I went with the Leica Pro 32's, 4 oz lighter. But might change my mind - have had very good luck with the Sig 2400abs.
