Hi @yhaulez this was a great search. So here I will leave my opinion.
Pros:
- It is very useful for all that diver who wants to protect himself from all shark or other marine species.
- Create sound that is unpleasant for sharks which makes them move a little further.
- It has a rechargeable battery which is charged through a USB port.
- It really works when you're under water and out of water.
- This technology has no adverse effects on the human body and sharks as well.
Cons:
- None for this hunt.
