On the 18th of February I finaly did some Ice Diving.

We did meet with some fellow MKVI Rebrather divers at Knivsåsens stenbrott (Dalby stenbrott) in Sweden to do some diving.

This was the first time I did some Ice Diving, and I did love it.

Thanks to Mikkel, Nico, Rene and Anders for a great day.

Here is a few pictures from the dive site, some of the divers is from another group.

If you wonder why they are lying around on the ice, it was while wating for another group to get up.

Here is a few youtube videos filmed by Submis.

p.s. I know my inflator is leaking, have to get it checked.

Back in January 2011 a Poseidon Discovery MKVI rebreather diver called Submis posted a thread on the www.Rebreatherworld.com forum:

Poseidon MKVI log files

He had found out, what some of the fields in the Rebreather log files did mean, and used Excel to create a graph.

It caught my interested, being a software developer I immediately started to create a program to make it easier to create and compare these graphs.

I would love to get feedback and ideas for further development of the tool. Either post as comments to this post, or better in the above Rebreatherworld thread.

Here is a few example of the graphs from a dive I did in Sharm el Sheikh last summer, including a screenshot of the User-interface where I Compare PO2 values with the PO2 setpoint.

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.
