Best Underwater Drones You Should Buy

Gone are the days when underwater drones used to be extremely expensive, so expensive that they were almost prohibited to buy unless you were a military person, an underwater researcher or a prestigious owner of an oil and gas company. These underwater vehicles were big, bulky and not-so easy to operate, at least not as easy as they are today.

The commercialization of underwater drones started just a decade ago but their technological advancement since then is mind boggling. They have become smaller, cheaper, faster and last but not the least, ‘easier to operate’ than any time before in the history.

As the technology is advancing, underwater drones and ROVs are gradually becoming more popular among the ocean explorers, hobbyists and underwater filmmakers alike. So much so that it is almost impossible to imagine a modern ocean explorer or an underwater filmmaker without an underwater drone.

If you fall in the category of those who cherish a genuine curiosity in their hearts about underwater exploration and filmmaking, you might want to ask – what are some of the best underwater drones available in the market? Or what factors should you take into consideration before buying an underwater drone?  

If you really have decided to buy an underwater drone, but do not know the answers yet, we’ve got you here. First of all, underwater drones are not cheap and secondly, there are a few things you should consider before jumping into a conclusion one which one is the best underwater drone for you.

Some of the important things to consider are the price, off course, then comes the mood of control, wired or wireless; then you should check out the battery life because you don’t want your underwater treasure hunt to end halfway all of a sudden; and last but not the least, the camera configuration and its performance in the murky depth of the sea where hardly any sunlight can reach. 

It’s important to know what purpose of yours will be served by the underwater drone you are going to take home with you. So here we would like to present you a review of some of the best underwater drones available in the market so you can decide for yourself which one to buy.

Battery Life: 3.5 hours 
Country: China 
Price: $1799

Diving Depth: 100 meters 
Battery Life: 3 hours 
Country: United States 
Price: $3483  

Blue Robotics BlueROV2 has 6 vertical thrusters mounted to the outside unlike its predecessors which had four thrusters. The additional 2 vertical thrusters have brought some powerful new capabilities in the ROV like six degrees of directional freedom, active control and pitch stability and increased payload lifting.  

When it comes to the pitch stability, the mini ROV is perhaps among the very bests in the category. You can move it through the water at full speed without any oscillation and imbalance. The drone automatically corrects its orientation for any imbalance or unusual dynamics in the water. The automatic self-balancing is particularly important when you need a steady camera view regardless of the outside condition underwater.  

The drone has strong control over both roll & pitch. And if you combine this with its feedback stability control, this means you can literally position it at any unusual orientation & still control the drone like normal.  

Blue Robotics BlueROV2 has already gained some popularity among the school going kids for project purposes, business owners, hobbyists and amateur explorers for its unique design and capabilities. Additional accessories that can be mounted to the drone includes grippers, sonar and thrusters (8 thrusters can be mounted at a time).
