CudaJet 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 without power?
Use this text to answer questions in as much detail as possible for your customers.
Will I get forced 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?
Before using the CudaJet Underwater Jetpack, you must be able to equalise your ears safely and effectively. Failure to do so can result in serious injury.
It is your responsibility to learn proper equalisation techniques before diving. Equalise early, equalise often.
Do not use the Underwater Jetpack if you are unable to equalise.
Descent may require practice and control; ascent is typically straightforward and often occurs automatically. Always prioritise safety and listen to your body. If in doubt, stop and return to the surface slowly.
What mask should I wear?
For safe operation of the CudaJet Underwater Jetpack, you must wear a diving mask that covers your nose. This allows you to equalise pressure during descent and helps prevent ear or sinus injury.
Do not use swimming goggles or any mask that does not fully enclose the nose.
How deep can you go?
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.
How Fast Is the Underwater Jetpack?
The Underwater Jetpack can travel up to 3 meters per second. This speed is controlled via the trigger in the hand controller to provide smooth variable thrust control.
This is faster than any swimmer! Watch here
How do you stop moving when flying the Jetpack?
As soon as you let go of the trigger, the massive drag from the water will stop you almost instantly.
What happens if I run out of battery?
The Underwater Jetpack includes multiple battery warnings to alert you when the battery is running low, signalling that it's time to head back to land.
As the battery nears depletion, the Jetpack will automatically limit its power to help you cover longer distances on low power, ensuring you can return safely even if you've ventured too far.
If the battery reaches 0%, the motor will stop, and the Jetpack will float at the surface, allowing you to swim or wait for assistance if needed.
