Risk vs Fun

All sports involve inherent risks, and it is your responsibility to educate yourself and take necessary precautions to minimise the risks associated with Free Diving and the Underwater Jetpack before participating in this activity. While Jetpacks offer an exhilarating experience, it’s easy to overlook potential dangers.

You MUST read the product manual thoroughly. This page outlines some—but not all—of these risks. With this knowledge in mind, you’ll be prepared to enjoy an unforgettable adventure like no other!

You must read the product manual before using this product.

Warning! Please Take Care.

Intake Warning! Do Not use with long hair.

Critical Safety Warning:
Do NOT use the Underwater Jetpack if you have long hair without taking strict precautions. The device relies on powerful water intake to propel you, and any loose hair or objects can be immediately sucked into the intake, leading to serious injury or device malfunction.

While the Jetpack is equipped with a protective mesh, this barrier does NOT prevent smaller items like hair strands from being pulled in. If you have long hair, you MUST securely tie it back or cover it before use. Failure to do so is a serious safety risk, and you will be fully responsible for any injury or damage resulting from improper use.

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 breathing?

Our products are NOT designed to provide air during use. If you intend to go underwater, you must hold your breath and resurface when needed. These products do not include an air supply, nor are they compatible with any external air sources.

Please DO NOT attempt to breathe underwater while using our products. As a result, there is no risk of lung overexpansion, which is typically associated with scuba diving.

This product is intended for assisted free diving, meaning you will hold your breath throughout the dive and resurface with only the 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.
