The IS-MIX is tested for jumps in water up to 3 metres. To prevent damage to the IS-MIX, this should be performed as follows:

1. Keep your right hand on the full face mask and your left hand on the high-pressure connection in order to protect the IS-MIX from impacts in the water.
2. Take a large jump into the air and turn your body to the right to reduce the risk of the IS-MIX hitting the edge.
3. Lean your upper body slightly forwards to protect the IS-MIX from impacts in the water.
4. To cushion the impact, put your legs together with your fins horizontal.
