The Zhiyun-Tech Rider-M is a mini 3-axis gimbal stabilizer for GoPro cameras. Highly compact and featuring a 1/4"-20 threaded mounting hole on the bottom, the Rider-M is designed to be used mounted on various support accessories, such as suction cups. The Rider-M supports remote operation using an optional remote control or an iOS/Android app available from Zhiyun-Tech. So, for example, you can have it mounted on a suction cup that's attached to a moving vehicle and control it wirelessly from your phone, which it connects to via built-in Bluetooth, or from the optional remote control. The remote control unit works from up to approximately 30 ft away when there's no interference. When used manually, you can set the Rider-M to a desired static angle by simply adjusting it into that angle with your hand and holding that position for a second until the angle is locked in. Additionally, a double-stopper design for the pan axis allows for ±320° pan movement and panoramic capture. The Rider-M uses brushless servo motors that operate at 4000 Hz. The Rider-M also offers a 3.5mm video output that allows you to connect a viewing device to monitor your images in real-time. This stabilizer comes with four batteries and accepts two at a time that provide approximately three hours of runtime per the pair.
