I just purchased one of these for my 10x42 EL Range TA binos and spent a week spotting for spring bears. I didn't didn't feel the need to pack the BTX with 65mm objective up the mountain once. Running the binos loose until something was spotted and then breaking out the tripod with this mount was perfect. Even the Phone Skope was flawless. The detail in the pictures through the 10x42 Swaro with my Galaxy 23 Ultra were amazing. Will only pack Swaro spotter for 2mile + spotting.
