When you already own a newer HoodLoupe model with inter-changeable bases and your base is sized for 3.0 inch LCD screens; the H32B base mounts is what you need to fit up to 3.2" LCD screens. The HoodLoupe optical module is placed over the base with the latches snapped into the locking position. You can easily switch between mounting bases to accommodate the LCD screen size you will be viewing for the day. The base integrates with all Hoodman live view mounting plates.
