This invention is really useful.Now more and more tourists come to the countries that have oceans,seas...but nobody knows...is there any dangerous fishes or animals there???So many of them worried about that!But with this product..we don't need to care about anything...peace of mind...!The most important thing is it's effective and it does not harm to environment and it doesn't polute the ocean!This product is good and really needed to divers and inventors.They can be safety in this new invention.Maybe they will buy this more than other people or tourists that just swim for a small period of time...and tourists usually swim in a safety area that be checked and proved.And I think that it's not very cheap cause this is the new invention and it has high technology details such as electric field and rays...
