What is an Underwater Jet Ski?

Sure you know what a jet ski is, but do you know what an underwater jet ski is? They are not as common, but boy are they fun! I will explain exactly what this toy is and why it is getting popular.

An underwater jet ski is a 3-foot long handheld jet ski that can skim across the surface of the water or descend below the water, like a submarine. It travels at around 3 – 10 miles per hour.

These watercraft toys work in pools, oceans, lakes and the battery life is around one hour.

Underwater Jet Skis

If you have ever wanted to speed through the water like a shark or a mermaid, you will be dying to try out an underwater jet ski. An underwater jet ski is just what it sounds like. It is a device that is meant to take you through the water, and even under it.

It differs from a jet ski, of course, because regular jet skis are supposed to keep you floating on top of the water, or help you skim and do tricks across it. The underwater version is designed to be able to go underneath the water.

You have to get used to holding your breath or bring snorkeling gear to enjoy this jet ski. They are a bit trickier to operate than jet skis, at least at first. Additionally, you can usually only use an underwater jet ski for an hour at a time.

However, these things are so much fun. Just see what I am talking about.

The device works by pulling you behind it. By that, I mean that you grip onto the handles and put the device in front of you. When this is done correctly, it propels you through the water. You can aim the handheld jet ski to go below the surface or to go on top of the water.

When you get really good, you can bob in and out of the water, sort of like a dolphin. Underwater jet skis have become increasingly popular, but they are pricy.

The capability and the price of jet skis vary between the brands/models. Let’s break it down more.
