Mount your Mars 300, 400, or 400S receiver or transmitter onto a shoe mount with this Shoe Adapter Mount from Hollyland. The aluminum adapter attaches to the transmitter or receiver unit with the 1/4"-20 screw, and it mounts onto a standard shoe mount, such as the one on your camera or cage, using the shoe adapter base. The mount tightens in the shoe mount using a knurled thumbscrew.
