Anyone who cringes at the idea of being stuck in a water filled underground network of blackened caves should look away right about now!
This asphyxia inducing video of dad-of-one Ian France, 49, and his pal Ashley Hiscock, 26, down in the underground sumps of Bagshawe Cavern, in the village of Bradwell, in the Peak District is enough to make anyone take a deep breath.
The thrill seeking pair filmed their underwater adventure as they squeezed through tiny gaps in an underground British cave.
In the claustrophobic video, both divers can be seen crawling through the active stream cave and squeezing through gaps as small as two metres.
Wearing a wetsuit and wellies, Ian and Ashley were forced to use side mounted oxygen tanks to ensure their body could fit through the especially shallow series of streamway caves.iPhone transfer software
The entrance to the caves is through a flowing stream and Ian and Ashley were immediately greeted with a shallow water filled tunnel.
Bagshawe Cavern, in the village of Bradwell, in the Peak District is a cave diver's delight
