Risk vs Fun

All sport contains risk. It is your responsibility to make sure you educate yourself and mitigate all risks of Free Diving and the Underwater Jetpack before you participate in this activity.

Whilst the Jetpacks are very fun, it's easy to forget about the risks. This page highlights some, but not all of these risks.

With all that in consideration, you are ready to have some fun and experience nothing like ever before!

Safety FAQ's

What happens if I drop the controller?

The motor will cut out, and you will float up to the surface.

The controller is hard-wired to the Underwater Jetpack to prevent this from being lost whilst in the water.

If you do let go of the controller and can't see it, simply put your hand behind your head and trace the cable back to the handle.

Will I sink?

No. The Harness provides buoyancy to the user, so you will be able to sit comfortably at the surface.

How do you control direction?

The direction is controlled simply by moving your body.

The Underwater Jetpack has no way to control your direction, it can only provide thrust!

Will I shoot down to the bottom of the ocean?

The Underwater Jetpack can not control your direction.

Also, the Jetpacks are fitted with a 3-meter safety limit, from factory settings.

When you hit 3 meters, the power will cut out, and the buoyancy from the harness will make you float to the surface quickly.

This prevents inexperienced users going too deep, too quickly.

Warning! If you are a new diver, do not apply MAX throttle until you have good control of the product.

Read the product manual on how to adjust the safety limit.

Will I get cold?

Moving fast through the water will cool your body down, even if the water feels warm.

Please make sure you have adequate clothing on.

If you feel cold, get out of the water and warm up.

What about lungs?

We do not allow you to breathe air whilst using our products.

We do not include any air source or means to attach air to the product.

Do not try and breathe air underwater while using our products

Therefore, you will not be able to get a lung overexpansion issue as seen in scuba diving.

This is simply assisted free diving, so you will finish the dive with the same amount of air you started with.

Equalise! What about ears?

You should learn how to equalise your ears properly before you dive.

Going down may take some practise but going up is simple and often automatic.

Going below 3 meters?

While the product is rated to 40 meters, you should seek out professional training and advice from a free diving school or instructor if you want to dive below 3 meters.

What is SI (surface intervals)?

Surface interval is the time between consecutive dives that the user spends on the surface breathing normally.

Surface time allows the user to recover oxygen and remove excess CO2 and nitrogen from their body.

The deeper you go/the longer you are underwater, the more surface time you need between dives.

As a general rule, for dives less than 25m, you rest on the surface for twice the dive time.

Eg. A 1 minute dive would require 2 minutes rest at the surface.

Can I get the Bends? (Decompression Sickness)

Yes, although this is highly unlikely under normal use.

Always make sure you are taking adequate rests in between dives.

The full safety section must be read before using the product, this will be provided in the product manual.

Warning! Please Take Care.

Intake Warning! Do Not use with long hair.

Do not use the Underwater Jetpack with long hair. Water must flow through the Underwater Jetpack in order to propel you forwards.

This means items or personal body parts such as hair can get sucked into the intake.

If an item enters the intake, you could be injured or cause damage to the product.

Whilst there is a mesh to prevent large items passing through, smaller objects may still pass through the mesh.

If you have long hair, it is your responsibility to properly secure this before using the product. You must ensure there is no possible way it can enter the intake.
