For our Russian cave diving friends we have an article on our blog www.protecblog.com Как подготовиться к Кейв курсу

Спасибо, начал готовиться.

You probably should keep bringing it rather to forum.tetis.ru While the site has certain reputation it enjoys higher popularity rating among russian divers than CDF. Kinda like TDS of Eastern Europe.

I've heard your concern diveworld1, my YT will no longer bother you. And I can assure you - "material collection was minimal and done professionally".
