The compact TransMount Image Transmission Module accessory can be mounted under the quick release plate. Up to 3 devices can be connected to your stabilizer, including not only smartphones and iPad, but also professional monitors.
Great gimbal for DSLR and mirrorless cameras. The version in aluminium is better quality though. Really intuitive to use et précise. If you need some course to get the most out of your gimbal, I recommend Brandon Lee gimbal course.
