I purchased my original Tricer bino adapter back in 2022 for a desert bighorn hunt. It became the star of the show for those lengthy glassing sessions in the desert. I recently purchased a second adapter because I got tired of moving my original adapter back and forth between my lightweight backpack glassing system and the heavier tripod and binos that I leave permanently in my Jeep. I have tried other brands of adapters since purchasing my original Tricer adapter, but when it was time to make a purchase it was Tricer x 2.
