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.
