When we say scuba diving is a sport for everyone, we truly mean it. Though there are certain physiological maladies related to asthma or perhaps sinus problems, diving is an exceptionally hard sport to find a reason for not being able to participate it. All manner of disabilities can be mitigated to get under the waves, from quadriplegics, deaf and blind divers and more. In fact, there are very cool companies such as Indigo Industries that creates equipment for adaptive divers!

You can check out their line of adaptive equipment at https://www.indigo-industries.com/adaptive-diving
