Insta360 Flow 2 Pro Smartphones Stabilizer Gimbal. The updated white Flow 2 Pro Smartphone Gimbal Stabilizer from Insta360 allows you to capture and stabilize smartphone footage in an all-in-one form factor with 1-tap pairing, native iOS tracking, a 10-hour runtime, and an integrated ring light to display when tracking is enabled. The included magnetic phone clamp secures smartphones 2.5 to 3.3″ wide to the gimbal. Thanks to the gimbal’s built-in 8.3″ selfie stick and tripod legs, there’s no need to bring additional expansion mounts.
