Solo Cave Diving and UK Sump Conditions | Cave Diving Group
Saved by uncleflo on January 17th, 2022.
The CDG believes that their cave diving procedures, developed by continuous improvement over 70 years, represent the best way to produce a well trained, intelligent and alert diver. Solo cave diving in the UK can trace its roots back to early dives by Graham Balcombe and Jack Sheppard in Swildon’s Hole in 1934. The procedures developed in the 30’s were formalised by the founding of the Cave Diving Group in 1946. A constant theme throughout the existence of the CDG has been to adapt materials and methods to the job in hand and to be open to continuous improvement. Cave diving has become extremely popular throughout the world. Florida is one of the regions blessed with many cave diving sites of outstanding quality and easy access. Consequently, there has been an explosion of popularity in cave diving in the USA. It is estimated that there are as many as 20,000 cave and cavern divers in Florida alone. These divers are organised into a number of national bodies including the National Speleological Society, Cave Diving Section and the National Association for Cave Diving. The generally agreed advice from this wealth of experience is that cave diving in the USA should be conducted by teams of divers in a buddy system and that solo cave diving introduces an unnecessary level of risk. Despite this advice the Cave Diving Group continues to recommend solo cave diving as the safer alternative for UK sump conditions. Why is that?

Boat Lightning Attenuation Onboard
Saved by uncleflo on May 11th, 2021.
According to published reports, in the US out of the annual average of about 100 deaths due to lightning, approximately 13 are aboard boats. Suffice it to say that if lightning is a hazard where your boat will be used, a plan should be developed to deal with the possibility of a direct strike. In the Pacific Northwest lightning is relatively rare. In Florida, some areas annually have more than fifty strikes per square mile..! According to the well known lightning researcher Ewen Thompson, lightning can develop on the order of one hundred million volts, peak currents of tens of thousands of amps, and generate temperatures of some fifty five thousand degrees. Fortunately, it lasts only a fraction of a second, but within that time it can be deadly and / or very destructive. A lightning strike involves an extremely rapid change in an electric current, generating a momentary but extremely powerful magnetic field. This electro-magnetic pulse (EMP) will readily induce currents in adjacent wiring. Currents induced in wires by the EMP from a lightning strike may do some very weird things, such as fry every piece of electronics aboard. A strike nearby or on another boat can fry the electronics aboard your boat without even requiring an electrical connection or direct strike.

A considerable body of evidence proves, beyond reasonable doubt, that microwave radiation from mobile phones and cordless phones cause a significantly increased risk for brain tumors. In addition, increasing evidence is indicating that it causes disturbed brain function, damage to the genes and other disturbances..
