Hi @ tornad, this is a very interesting hunt.
It is very important that the device is small in size and mobile.
And when it gives excellent visibility images we have a full hit!!

Application is wide:

• aquaculture research
• yachts, sailboats etc.
• search and rescue
• underwater photography
• diving
• fishing (looking where the fish is)
• tourism
• education
• fun

What has a "wiring" is a limiting factor but a "skilful" steering wheel can reduce it to a minimum level (you can check the route before you let your dron in action ...).

Good luck with hunting.
