What are underwater Drones?
Underwater drones are also termed as unmanned underwater vehicles or Remotely Operated Underwater Vehicles or ROUV/ROVs for short. Even though they received popularity recently, they were present for quite a long time. Earlier they were only designed for military purposes.

They were utilized as minesweepers in the military. Nowadays, they are also used in all fields including industrial purposes. Underwater drones are also used in sub-sea construction. In recent years, underwater drone manufacturing has been expanded and it even entered consumer tech space.
In simple words, the underwater drone can be understood as a miniature version of submarines. The only difference is, the drone is unmanned.
Comparatively, it is difficult to send radio signals in water than air. Hence underwater drones are not controlled using the remote control. These drones are autonomous and they are made to navigate with onboard sensors and computers.
*It should be noted that ROVs are technically different than DPVs, which are Diver Propulsions Vehicles. While they look similar (small form factor, battery powered, propellers) ROVs are not used to move humans, whereas DPVs aka underwater scooters are.
Why would you want an underwater drone?
There are plenty of ways underwater drone is used today. It is utilized in almost all industries. Let’s look into some of the uses of underwater drones.
Infrastructure Surveys
Infrastructure always demands routine inspections. So, long term care and success of infrastructure always depend on these inspections. Earlier, an inspection of underwater was really difficult and strenuous, and dangerous. But not today since underwater drones are being used for these inspections.
Underwater drones have resulted in better ways of collecting and recording the best possible data. This is helping in improving the quality of underwater infrastructures like bridges. Some of these locations are too dangerous for even the most experienced divers to stay calm, so ROVs are the better solution. The best part is, analysis through drone is highly cost-effective and easy.
Recovery and Search Missions
Underwater survey missions have become very easy by using these underwater drones. They are helping in detecting as well as mapping all kinds of submerged wrecks, obstructions, and rocks. They are detecting obstructions that are even impossible to navigate using other commercial and recreational methods.
Underwater drones are very useful in all kinds of recovery and search missions. You can easily map a missing aircraft or some wreckage by utilizing these drones.
Military Duties
For military underwater drones are very useful. They will help in detecting and hunting submarines and they are also useful in neutralizing mines. Since we are provided with advanced technology, these drones have become scalable and dependable. The best part is these drones can perform their job with a high degree of autonomy.
Conservation
These underwater drones have opened up many more possibilities. It has become easy for scientists to explore undersea without manual intervention. Along with scientists and engineers, today even common man with interest in underwater can explore as much as he needs.
Photography
Underwater photography is not easy and people were struggling to capture pictures underwater. Using autonomous drones you can easily explore underwater and take pictures of undersea.
Things to Consider When Buying a ROUV
There are many things to consider before choosing an underwater drone. Most importantly you need to look for 6 major factors. They are wired or wireless models, battery life, maximum depth, camera resolution, top speed, and price.
Along with many other things like weight or shape of the drone these 6 factors should be considered when you are buying an underwater drone.
Remember that these devices are expensive and you need to make the right decision before making the final choice.
Wired or wireless
Even though most of the underwater drone models released today are wireless, there are some wired models as well. It all depends on the usage and your personal preference. You can go for wired or wireless models. These are the two major categories in drone models. The only thing you need to understand here is wired models are not autonomous whereas wireless is completely autonomous.
Battery life
This is the most important thing and you need to check for the battery life and its durability before buying a model. You cannot finish the undersea exploration quickly. So, it is better to look for models with better battery life.
Maximum depth
The depth requirement depends on usage. If you are buying it for hobby or just to explore on your own you may not need higher depth models. If you are buying an underwater drone for study purposes, then you should pick the drone with very good depth.
Autonomy
There are plenty of varieties in underwater drones. Some may come with shorter flight time and others can fly longer.
Camera resolution
Underwater drones offering high-resolution cameras are expensive. If you need a high-resolution camera then you need to pick the high-end models. It all depends on the purpose and your personal preference. If it is for military usage and surveys, a high-resolution camera is necessary.
Along with camera resolution, make sure you have a ROV built for your purpose. If you are doing deep dives, night dives, or cave dives, make sure your underwater drone has adequate built in torches designed for extended underwater use.
Top speed
When it comes to exploration and hobby, speed is not a very important factor. Of course for other uses, you may have to consider speed as well. When the drone is used for detecting some missing aircraft or in some emergency, then it’s top speed matters a lot.
Price & Operating Costs
Since there are plenty of options available in the market, it is up to you to decide the best model. The selection of the model depends on the purpose of buying the drone. If it is for fun, then there is no need to go for expensive models. But, if you are buying for professional purpose then it is worth paying for expensive models.
These are the key aspects to consider when buying an underwater drone. Along with all these, you will have to consider the pros and cons of the model.
Below are some of the best for each category we could find after spending hours researching dive exploration blogs, dive forums, and online reviews from real divers.
