Underwater drones are significantly more expensive than their aerial counterparts, costing a minimum of about $500 and the more expensive ones being $6,500.
The most common image that comes to mind when it comes to drones is a little remote-controlled device that’s meant to fly high up into the air, whether for fun or various professional purposes like aerial drone photography. However, drones aren’t limited to the sky. Theoretically, you could stick a remote-control system on just about any kind of small vehicle for any kind of environment, including the ocean’s dark depths.
Underwater drones very much exist, and they’re frequently employed by researchers such as marine biologists and archeologists, as well as professional operations that salvage vessels and inspect underwater oil lines from floating offshore oil rigs. Just as there are both professional-level and consumer-level flying drones, there are also professional and consumer-level underwater drones, with the latter being used mostly by recreational divers and underwater photographers.
