'The Royal Australian Navy using the Shark Marine NAVIGATOR underwater sonar and navigation systems - encounter with a shark.   I downloaded this video from the Australian News site several years ago as it showed our diver-held sonar and navigation system in operation. Recently I received an email request from a Grade 6 student for information on sharks. I explained to her that we didn\'t really deal with sharks but sometimes our equipment does. I then posted this video to my personal Youtube site and sent her a link - not quite sure how all the rest of you found it..... Not my video but thanks for the likes!!'
