■Entry

Please follow the instructions of the team leader for the entry procedure.

When entering from the hull of a small boat whose feet are unstable, giant stride entry cannot be performed, so back roll entry will be performed.

When you are sitting on the hull of the boat, it is a good idea to pinch the gauge and octopus regulator by using your both feet to prevent them from getting caught on the side of the boat during entry.

During entry, hold the mask frame and strap firmly so that the mask does not come off your face.

Also, pull the chin firmly so that the back of the head does not hit the valve when landing.



The gauge is sandwiched between both feet.

Make sure there are no people or floating objects on the water before you enter.

When entering from a large boat with stable feet, giant stride entry is common.
