Narked at 90's diving blog

In this blog post, we'll compare three decompression stop algorithms used in technical diving: Bühlmann Gradient Factors (GF), Varying Permeability Model (VPM), and Reduced Gradient Bubble Model (RGBM).

They've been overwhelmingly important in preventing decompression sickness, but new divers tend to find gradient factors confusing.

Among the most common models in this area are the Bühlmann gradient factors. This blog delves into what they are and also explains M-values.

British divers have been wondering about the implications of a recent ban on dangerous knives. Will these changes in the law affect the type of equipment that can be used on dives?

In this blog, we take a look at the wording of these new regulations and see what impact it has for recreational and technical diving.

Shearwater Research has recently issued a product recall of their Petrel 3 dive computers. A recall for such a popular device is going to take some time. Their fix is just being tested and as you can imagine, we will be swamped with units from around the world.

We were sad to learn that GoDive has recently taken the sad decision to depart from the diving equipment marketplace. Last week, the team at the PADI-accredited outlet announced that difficult trading conditions led them to end their operations:

"For a long time, we have ploughed on and supported the business, but sadly it can’t go on for ever. We have long championed and helped support the smaller dive shops and the dive boat skippers, without them there is no UK diving."

Nobody wants a nosebleed, especially when diving. It's a problem that usually affects new divers, but even the experienced aren't immune to this issue.

What causes your nose to bleed when diving? How can equalisation help and what are the main methods? And how do you handle nosebleeds during a dive? This blog post takes a detailed look into these areas.
