The DJI Osmo Action Floating Handle helps to make the camera float in water. The waterproof case helps to protect the Osmo Action in water of depths up to 60 metres. The wrist strap helps to enable you to fasten the camera to your wrist so you do not worry about dropping the unit while swimming, surfing, or more. The kit includes an extra battery for an extended shooting time. All accessories are also stored conveniently in the Osmo Carrying Case so you can take the Osmo Action where you need to go.
