Cave Diving Links

The national body for caving in England, Scotland and Wales. The association is non-commercial and exists to provide a national voice for cavers and to act as a go between between government and the caving community.
The web site contains information on the organisation structure, administration, conservation and access, training, safety, equipment. 
The site is well laid out but the home page is mostly just a list of links to the many other pages that hold information. This could be off putting, however this list could be scanned quickly to see if the item you are looking for is present. This is not a site for advertising caving to the general public and its format reflects that, however it does hold the information necessary to allow you to find a list of the nearest caving clubs to your area and provide you with an information resource on how to cave. The site is fast loading and does not generally use many graphics/pictures.    

Martin Farr's cave diving site. Martin is a very experienced caver and cave diver. He has written several books on these subjects as well as having led many international expeditions, and one point in time held the world record for a cave diving penetration in the Bahamas. This is a commercial site and its purpose is to advertise Martin's services as a lecturer and an instructor for the training of caving and TDI cave diving courses.
The web site contains information on his books, courses, lectures, and photos. 
The site is well laid out and contains a selection of very good photos of caves and cave diving. The site makes good use of graphics but has kept these to a small file size which does not impinge on download speed. The main photo gallery allows you to select which photos to enlarge. 

Details the achievements and exploits of various French cave diving expeditions, especially deep diving trips. This is a non-commercial web site but does recognise its commercial sponsors. The expedition was carried out by various team members, but especially Dr Jerome Meynie. The web site details the dives that the expedition made, the expedition members, photographs, location maps, and a list of links to related sites. 
The web site uses a front page that allows language selection for French or English, and a then a link page for the various expedition sites. The pages are black background with a white text, using yellow for keywords. The site includes many pictures from the expeditions and is kept up to date.   

The International Association of Nitrox and Technical Divers has become one of the leading training agencies for all aspects of technical diving. The web site details the history of the organisation, its instructors and courses, and much information relevant to the type of diving it teaches. This is a commercial web site and as such can be seen as an advertisement to their services. 
The organisation initially started by offering courses in use of Nitrox (air with a higher percentage of oxygen) in 1985, but soon expanded to cater for all aspects of technical diving. It offers two courses, Introductory Cave Diver and EANx or Air Cave Diver, in addition to the relevant instructor grades. This is a US based agency but the site does include the links to the UK representatives. The site also includes some pages and information on cave dives in the US.
The web site initially opens on a page that redirects you to the main site, the address of which is only seen as an IP number. You are then directed to a complicated home page that makes a lot of use of colours, animated graphics, colours, drop down lists, and advertisements. These do not overly infringe on the reading and understanding of the page but will affect down load time. This page covers much more than one screen of information and if you do not scroll down you will miss much of that present. The site can be over complicated in places with the use of frames (up to 4 at one point), to the extent where it is hard to determine what is happening.
