Scuba Diving History
Scuba diving history Scuba history from a diving bell developed by Guglielmo de Loreno in 1535 up to John Bennett’s dive in the Philippines to amazing 308 meter in 2001 and much more… Humans have been diving since man was required to collect food from the sea. The need for air and protection under water was obvious. Let us find out how mankind conquered the sea in the quest to discover the beauty of the under water world. 1535 – A diving bell was developed by Guglielmo de Loreno. 1650 – Guericke developed the first air pump. 1667 – Robert Boyle observes the decompression sickness or “the bends”. After decompression of a snake he noticed gas bubbles in the eyes of a snake. 1691 – Another diving bell a weighted barrels, connected with an air pipe to the surface, was patented by Edmund Halley. 1715 – John Lethbridge built an underwater cylinder that was supplied via an air pipe from the surface with compressed air. To prevent the water from entering the cylinder, greased leather connections were integrated at the cylinder for the operators arms. 1776 – The first submarine was used for a military attack. 1826 – Charles Anthony and John Deane patented a helmet for fire fighters. This helmet was used for diving too. This first version was not fitted to the diving suit. The helmet was attached to the body of the diver with straps and air was supplied from the surfa 1837 – Augustus Siebe sealed the diving helmet of the Deane brothers’ to a watertight diving suit and became the standard for many dive expeditions. -

2004 AQUANAUT GUIDE SCUBA REGULATORS 67 Adjustability Environmental Seal There Are Two Primary Adjustments Available on Modern Regulators
SWIM REGULATORS 65 Performance Many people believe performance is the major criteria in the choice of a regulator. Certainly, you should choose a regulator that is appropriate for the types of diving you intend to undertake. Most modern regulators will perform adequately under normal demand at moderate depths. The deeper you dive and the harder you breathe (for example, swimming against a current at depth) will result in a higher demand on your regulator. So if you were planning on diving in demanding conditions, it would pay to invest in a high-performance regulator. Generally though, when it comes to judging performance, it pays to remember that the greatest testament to a regulator is its performance under harsh environments. Australia’s Far North Queensland (FNQ) has the highest concentration of dive equipment usage in the world. Gear may be used three to four times a day, seven days a week. These professional operators recognise the need for the best equipment. They also understand that the materials used and the design are critical for their customer’s ultimate safety and comfort. Aqualung regulators have proved to be the most popular choice in FNQ and resorts around the world. Unlike Aqua Lung, very few companies make their own regulators. Most equipment suppliers outsource products or simply re-badge or assemble components from existing manufacturers. This makes quality control very difficult and encourages Scuba regulators are designed to reduce the high-pressure air from the scuba cylinder obsolescence. Suppliers will move from one manufacturer to another as either the to a level where the diver can breathe comfortably and safely. -

Choosing lenses can be especially confusing. Take wide angles. They’re great in low visibility and essential for photographing large subjects like wrecks and whale sharks. But how wide is wide? 95 to 100 degrees is what most professional underwater photographers consider to be the benchmark or standard wide angle focal length. Narrower angles often just don’t cut it. The Inon UWL100 provides up to 100 degrees. That’s twice the coverage of most cameras’ built in lenses. And substantially wider than the Olympus C5060’s own 70 degree wide angle lens and port combination. Conveniently the UWL100 is also a wetlens. You can remove and replace it underwater, changing lenses to suit your subject. And if you find even 100 degrees restrictive, you can add a dedicated dome port and expand your view by 30%. Inon make some of the best thought through and user friendly accessories for the underwater digital photographer.

INTRODUCTION AND RECENT INVASIVE AQUATIC PLANT MANAGEMENT The current invasive aquatic plant management program being conducted on Saratoga Lake is following a comprehensive plan that was developed over several years of investigations and studies. An integrated approach that utilizes winter drawdown, mechanical harvesting, hand-harvesting and herbicide treatments has been employed since 2007. These strategies were detailed in the Watershed Management Plan prepared by The LA Group in 2002, the Long-Term Aquatic Vegetation Management Plan prepared by Aquatic Control Technology in 2005, and the EIS prepared by The LA Group in 2007. -
