    There is literally a few thousand mines in Sweden, most are waterfilled and a lot of them are accessible. Logistics of access vary though and knowing which ones are suitable is trickier. The highest...

    That video is just a part of the conspiracy. The diver is obviously a giant.

    First of all, it is a random clip off of youtube. It is probably not part of a conspiracy to prove you wrong four years later. There are hours more of clips from various origins showing this and...

    Compared to caves mines are highly unstable from a geological sense but from a diving perspective these risks can largely be mitigated with knowledge and research. In our particular case Sweden is...

    The final argument against mines is usually the size of the system, quarries and 100 feet tunnels tend to be referenced. In this case maximum linear penetration from the entry site is approximately...

    I think I have an excellent argument. I can with confidence say that the entire cave diving curriculum can be completed in the mines in question without taking any shortcuts or doing skills and...

    Yes, I teach mine diving in mines which results in a mine diver certification card. I do this for fun because I enjoy showing the mines to new divers, it pays less than my day job. Now, do you...

    So basically what you're trying to convey is that mines are too big to learn something in? Apart from the fact that there is plenty to learn about cave diving outside sidemount tunnels it is normally...

    What cave diving (or rather overhead diving) techniques cannot be practised well in a suitable mine? The main hazards remain the same as does the protocols and skills. Mines and caves are different...

    The question then is if it's a good reason. I personally do not think so. Some caves are not suitable or complex enough for proper cave training and the same goes for mines. Using it as a reason to...
  11. Caves versus Mines from Frist Trip to Florida, Please

    The big underground mines of Sweden are typically cave like in scope and line layout. I’d argue that they are more complex than most river caves, at least when it comes to navigation. Also the...

    As someone who’ve dived both swedish mines and caves around the world I would suggest renting a guide/instructor to get a environment orientation. The flow will be entirely new and to me it is worth...

    Ursuit suits are popular here in Scandinavia as a good drysuit at a medium price point. The heavy/light line is similar to a TLS in material. There are cordura suits as well as the kevlar if you need...

    I like the methods - imagine spending an hour lying still in the freezing cold with a rectal probe :)

    There's another one here http://archive.rubicon-foundation.org/xmlui/handle/123456789/2380 which showed no difference in a real world application. They used neoprene suits which probably counteracted...

    I would suggest that it is because the difference in heat conductivity is barely noticeable when compared to air, the difference between air and helium is far larger.

    In 15 degree water you will only ever really need proper undergarments. Use wool and layering and it will be fine even for extended dives as long as you keep a proper amount of gas in the suit. My...

    And if you add sumps there are even more. Also we have mines which, in swedish conditions, I would argue are more or less the same as cave diving in everything but the name. The skills are the same...

    The gear sale could increase the prize pool for the first one to get out alive!

    My suggestion is a reverse auction exit scenario. Divers get to underbid each other on minimum gas allowed for a certain distance exit. The "winner" gets to try the dive ;)
