How To Choose Underwater Drones?
There's a few different factors to consider when choosing an underwater drone including:
The Price: Ultimately this is going to be the most important aspect in your search. You have to remember, unlike traditional drones, they aren't cheap. The technology required to provide signal underwater is far different to providing signal above sea level. You will also need to consider the features such as the depth, build quality and camera equipment that will impact the price.
Connectivity: You'll want to consider how to connect to your drone while underwater. Most drones still require a cable of some sort, due to the limitations with radio signals. However, as technology improves we're likely to see some form of wireless connectivity on the market.
Camera Quality: You'll want to ensure your underwater drone provides a high quality camera. The standard now is 4K which not all drones have, but to get the best quality you'll want this. It all depends on the water quality, the clearer the better, but choosing a good camera can help.
Depth: Some underwater drones can only descend a few metres, while others can dive down to depths of up to 250m. You should consider your use case and how deep you need the drone to go down which will likely impact the price and your decision to purchase.
Battery Life: You'll probably want a drone with a long battery life. After all, unlike traditional drones that require high powered motors to fly, underwater drones don't require the same so can offer longer battery capacity, up to 10 hours in some cases.
Range: You'll want to choose a drone that offers a decent range. There's no point choosing one that has a range of 10m as you will be only able to dive down 5m before having to return. Some of the more expensive underwater drones offer ranges of up to 1km.
After Sales Support: It's likely you will encounter an issue with your drone at some point and may need support or to make a warranty claim. It's important to choose a brand that looks after it's customers. Support and after sales service usually comes at a price, so if it's an option I'd definitely add an extended warranty or pay a bit more for peace of mind later down the track.
Why Buy An Underwater Drone?
There's a whole world to explore under the ocean and underwater drones are providing more and more opportunities to do that. The main reason people buy an underwater drone is for fish finding. Yes, it's the number one way to find the best places to cast your line, or see what's happening under the water.
Additionally, here are some of the most common use cases;
Search & Rescue: How many times do you see police divers searching for people who have gone overboard or missing after a drinking session. Rather than manual work, underwater drones can help to find bodies, missing items of clothing and boat wreckage's fast.
Scuba Diving: Scuba divers are another big market for underwater drones as they can follow and record scuba divers in action. Due to the huge depths some of them can accomplish, it's not uncommon to see them being used to train divers or record tour groups.
TV & Film: Underwater drones are regularly used in film and TV capacity as backup and additional coverage for traditional underwater cameras which divers may use. Some times the sea is too rough for traditional divers, so drones can be called in instead.
Recovery: The best example here is the search for MH370, the world's biggest mystery. Underwater drones have been used off the side of boats searching the ocean for any trace of this plane. Additionally, they can be used in your own recovery efforts, similarly to how this company found a missing Argentinian submarine.
