“Weightlessness” is surely one of the thrills of diving. To achieve it, a diver must have a buoyancy device, that allows him or her to intuitively and subtly control all vertical movements.
Whether you are using a classic ADV (”Adjustable Diving Vest”) or a rather tec-oriented “Donut” (the name derived from its shape) – make sure that your gear does support you.
A configuration with Donut, backplate and harness (including a crotch belt) will make sure, that your tank will move with you – and not “around” you. Properly adjusted harness and a mandatory crotch strap will make your trip on a scooter more enjoyable – you will lead the scooter and not the opposite.
When your gear starts to feel like an extension of your body (in contrast to a clumsy “backpack”), you are on the right track. Look out for a crotch belt, easy to reach dump valves, streamlined shapes, lots of buoyancy, support on the surface and robust materials.
Everything is connected.
Your buoyancy device will also influence your
trim and your orientation under water. Keep in mind, that the right combination of the tank size and size of your donut / ADV is the key for a comfortable
dive. Your buoyancy can be highly influenced when using a scooter due to big depth amplitudes. Remember to equalise this changes when you stop. Your buoyancy control system must be intuitive and efficient to react immediately.
Our recommendation will be different depending if you are looking for the single-tank wing or double tank donut.
