Comments about Scuba Sonics - AquaSonic Underwater Alarm:

After reading other reviews of this product I was excited to purchase it. I tested it out the very next day with underwhelming results: no one could hear it. On the surface, if the water protecting cap were removed it was very loud. Once the cap was replaced, the sound was no longer loud and was even worse underwater. I tried it on several subsequent dives in the Bahamas and I could not even hear it half the time myself. I am very disappointed in what should have been a very promising product.

This is the first product you can really hear underwater. My wife was able to get my attention every time she needed me. We both have one now and know we can keep in touch underwater. I wish I had bought two to start with.[...]
