Customer Review: Flip Soft Pouch for Flip Ultra
I was very disappointed when I received it. It is too small and therefore cannot be used on Flip Ultra. I like a refund.
Customer Review: Unneeded, not well made, don't buy it.
I bought this item because I like to have the original OEM products and accessories from a company when I make an electronics purchase (in this case, the Flip Mini HD with I am enjoying). This case is hard to open and get the camera into, the hook is cheap, and it is just pretty useless overall. Don't buy it. Get a third-party case that holds more (like the optional USB cable and stand).
Scuba equipment allows divers to explore many different water environments. Humans have had the desire to experience such underwater depths since before recorded history. This is known through numerous undersea artifacts which have been found in ancient civilizations. There have also been various depictions of divers which are dated back to these early times.
Of course, the most basic method of underwater diving was simply to hold one's breath. After that, the least complex forms of underwater gear were hollow reeds. These were cut and used as a rudimentary form of snorkel.
In writings dating back to Ancient Greece, many references are made to expert diving skills used in warfare. There are also many acknowledgments of primitive scuba equipment and diving techniques. These include such things as sponge gatherers holding a heavy stone for a quick and deep descent.
At this time, the physical dangers inherent in the act of diving were not understood. Of course, the increased pressure demands were still felt. In an attempt to counteract these difficulties, oil would be poured into the ears prior to the descent. Some oil was also held within the mouth and spat out once the bottom of the water was reached. A tether was used to pull these sponge gatherers back to the surface quickly as needed.
Air hoses as well as crude diving bells have also been mentioned in Greek writing as far as breathing equipment goes. Thinly sliced and polished tortoise shells were used as goggles around the beginning of the fourteenth century. This was done by Persian divers.
What is regarded as the first true diving bell was created by Guglielmo de Loreno. It was created in 1535. He used it to complete the first one-hour dive.
It is true that several different cultures during different time periods developed their own versions of diving bells. These bells were the first rudimentary form of scuba equipment which allowed divers to travel completely under water with more than one breath of air.
It may interest people to know that humans are not the only species who have made use of such design! In fact, there is a spider known as the diving bell spider who lives underwater despite its need for breathing air. These spiders construct webs that are very similar to diving bells which provide for all their oxygen needs.
