Best underwater drone? : comparative buying guide, test, review ✅

Written by Agathe Rosse

While flying UAVs have seen their popularity soar in recent years, recreational underwater UAVs are just beginning to make a name for themselves. It must be said that the piloted drone intended for airspace has been increasingly developed for individuals wishing to try their hand at aerial photography, with a fun and easy to handle control interface, far from the image of the first generations of military drones. As for the submersible drone, it took longer to become more popular with amateurs.

Both fun and ideal for exploring the seabed, but above all for filming or taking photos underwater thanks to an onboard camera, just as a helicopter drone allows exceptional aerial shots, the underwater drone allows you to live a unique experience of discovery every time you use it underwater. Are you looking for the best quality/price ratio for your new UAV?

Where to buy a cheap submarine drone?

The market for unmanned aerial vehicles (UAVs) is still underdeveloped because of the cost of the technology required, and there are not many competitors. As a result, prices are fairly homogeneous, indexed to those of the market with an increase according to the degree of functionality. Therefore, it is essential to go to a specialized shop if you want to buy your drone in a shop, otherwise you will find unstable gadgets. Not necessarily easy to find specialty stores near you, you might say. The best is still to buy your UAV directly from the manufacturer on the Internet, either via its website or through secure platforms such as Amazon.

Choosing the right submarine drone

A few criteria to keep in mind when choosing your UAV among all the drones available on the market. Focus on purchasing criteria :

The range

If the first UAVs were mainly intended for recreational and leisure use, the technological progress in this field has been so dazzling that today, fans of model aircraft or underwater modelling can pilot a high-performance UAV with a licence that requires pilot training. It is important to choose your radio-controlled UAV according to your level of mastery: it can be frustrating for a novice to try to navigate a professional UAV.

The price

As an indication, for a reliable and functional UAV, you should count around 1000 € minimum if you want a durable device. There are, however, a few light, compact and inexpensive models for recreational use with the right longevity and value for money, for €200 less. It all depends on how you intend to use it.

Photo and video performance

Automatic framing, image stabilizer, automatic brightness adjustment… Many multimedia features can help you get professional-quality videos, if you put the price tag on it. If you want full functionality, you have to choose the best: the HYLH 4K UHD submarine UAV.


Don’t forget to check the UAV’s autonomy, as the device can take several hours to recharge: the time to obtain a payload varies from zero to double depending on the type of battery. Obviously, devices for more intensive or professional use usually have a longer autonomy, or are constantly powered by a waterproof power cable.

Wired or wireless

Again, it all depends on what you’re going to use your drone for, and if you’re going to take it to hard-to-reach places, if you’re shooting from specific angles, you’ll be more comfortable with a wireless device. On the other hand, its autonomy will be limited.

Customer Service

It’s not always thought about, yet it’s an essential purchasing criterion before investing in such an expensive device: make sure of the guarantees offered and the quality of customer service in case of a problem. Even if the model you wish to buy is supposed to be reliable, it is better to avoid any risk of unpleasant surprises.
