Note - This attachment will work only with a specific / generic model of the chest mount or chest mount having a length of 86mm as shown below.
You may have to change the elastic strap of the chest mount to a non elastic band to have a stable setup.
Once the camera is mounted and the invisible selfie stick is extended, the camera may sway because of the elastic strap of the chest mount.

Insert the foam / rubber strip inside the invisible selfie stick holder and stick it using the double sided tape. This will act as a grip to hold on to the invisible selfie stick.

The assembly is intuitive and is as follows :

1 . The 'Chest Mount Clip' goes on to the chest mount, it's a snap fit and requires no screw or glue and is removable.
2. The 'Adjustable Arms' of 2in or 3in or both are attached.
3. The ‘Invisible Selfie Stick Holder’ is then attached.
4. Use any existing chest mount ‘buckle’ clip on the chest mount and attach the second ‘Invisible Selfie Stick Holder’.

Once the camera is mounted and the invisible selfie stick is extended, the camera may sway if the chest mount strap has not been replaced with the non elastic one.
During the kayak event, the life jacket helped the chest mount with elastic strap stay in one place.
