A quick update on my latest post related to scuba diving with hammerhead sharks at Cocos Island (Coco Island, Costa Rica). This video will give any diver a good idea on what to expect to see during the immersion. Don't be scared by the number, because during day hours it is very common to see schools of sharks formed by more than one hundred sharks. Enjoy!
I don't know if you notice the underwater communication equipment that these divers are using. I know they are professional divers and underwater video makers (probably using expensive underwater communications equipment), but my point here is that these devices are very useful in any situation.
Ocean Technology Systems (OTS) offers a product for sport divers called Buddy Phone®, the technical name of these devices is 'Ultrasonic Transceivers' or 'Underwater Communications Equipment'; another option is the one produced by Divelink. In my humble opinion Ocean Reef offers the best of the best, the Neptune Space product line...dream equipment not for the average sport diver.
