Poseidon has released information regarding the upgrade for the Discovery MKVI rebreather.

So now we can finally dive with trimix on the unit, and do deco.

The announcement can be read here: Press Announcement or below the images of the unit.

Personally I am going for the 60 meter trimix upgrade.

Poseidon Announces
Rebreather Technical Upgrades Program

Poseidon Diving Systems announced today their program for technical upgrades of the Discovery MK VI rebreather. The program will deliver 3 key upgrades: 40M Deco, 45M Tri-Mix and 60M Tri-Mix. All current owners of Discovery MK VIs will be able to use these upgrades as they become available.

Poseidon’s tech upgrade program has been designed with 2 key objectives in mind:

1. To allow all existing and future Discovery MK VI owners to expand the performance range of their MKVIs beyond the recreational envelope, should they wish to do so
2. To enable Dive Instructors to teach both recreational and technical courses on the MK VI

40M Deco: Firmware upgrade, using air as diluent

45M Tri-Mix: Firmware upgrade, using Normoxic Tri-Mix as diluent, with a choice of helium fractions

60M Tri-Mix: Firmware and hardware upgrade, allowing for manual addition

Upgrade pricing and availability will be announced at DEMA in November, along with certification levels required for each upgrade. All current and future Discovery MK VI owners will be able to use these upgrades.

Near Sharm El Sheikh, in the Straight of Tiran, there are 4 reef, Thomas Reef, Gordon Reef, Jackson Reef og Woodhouse Reef.
All 4 reefs are worth diving, but specially one of them is really nice, where i have had 2 very good dives.

The dive site I am talking about is Jackson Reef, what is so existing about this reef, is the canyon also known as The Thomas Canyon.

This canyon starts at around 35 metres of depth and continues down to around 100 metres. At about 40 metres, 55 metres and 90 metres, there is sort of an arch across the canyon.

One special thing about diving in a canyon, is the silence. Outside the canyon there is a lot of noise from the boats, the fish (yes they make a noise). But inside the canyon the only thing you hear is your own breathing.

I have had the please of going under the arch at 55 metres during a TDI Entry Level Trimix course, you need a lot of tanks to do such a dive, but the experience is GREAT.

In the following video you can watch a group of technical divers in the canyon.

Here you see some recreational divers in the shallowest part of the canyon.

2 divers from GUE has set a new world record for longest cave dive.
During the 7 hour long dive, the dived 11,25 kilometre, while carrying 20 tanks with 7 different gas mixes. As a ‘bonus’ after the dive, they had to do 15 hours of decompression.

Other than being the longest cave dive yet, it is also the longest dive between 2 different entry points. The cave system they dived, is the 4th largest in the world.

National Geographic has also an article about this dive: here.

On the GUE website there is another here.

According to this article (sorry in Danish): article we soon could run out of Helium.

Helium for trimix diving is already expensive as it is, but it does not seem to get any cheaper.

Therefore I am seriously considering getting a rebreather.
The model I want is the Sentinel Rebreather, but £5400 + extra for the course is quite a lot of money.

But I am ‘afraid’ i am doing it anyway
