TBT August 13th 2015

Posted on August 13, 2015 at 2:35 PM

As I was thumbing through the July 1969 issue of Skin diver, I came across an ad for underwater communications via a megaphone type device. As Scuba Divers, we know that when we hear sound underwater, it's very difficult to ascertain what direction it's actually coming from so I found it interesting that such a device would give one the ability to talk underwater. I wasn't sure I wanted to use this ad for this weeks TBT but a few pages later into the same issue and I came across an article where they actually put this device to the test. Below is the original ad and then the two page article. Have a read.

I have to express my appreciation to the writer for bailing me out of this particular predicament. After checking throughout the the web and obtaining techniques that were not beneficial, I thought my life was gone. Living devoid of the approaches to the problems you've resolved through your main guideline is a critical case, and ones which could have negatively affected my entire career if I hadn't encountered the blog. Your actual know-how and kindness in playing with every aspect was excellent. I'm not sure what I would have done if I hadn't encountered such a thing like this. I can also at this point look ahead to my future. Thanks a lot very much for this expert and effective guide.
