Prins Willem V
New Virtual dive site

I am glad to report that we have released the virtual dive site of the Prins Willem V; one of the most popular wrecks in Milwaukee.Prins Willem

The Prins Willem V is a 258 Ft. steel freight ship lying on her starboard side in about 90 ft. of water in Lake Michigan.

She was originally scuttled during her building to prevent capture by the Nazis and was lifted and finished in the late 1940's. Then, on October 14, 1954 it collided with the Sinclair VII tearing a hole in her side causing her to sink. All crew members survived during the incident thanks to a Coast Guard rescue.

Special thanks to Rick Richter at Silent Helm for providing images and videos for this project.
Product of the Month
Trimix Loading Meter
One of the new feature you will see in r10 is the Trimix Loading Meter.

As several of You know - and reminded me constantly - in r9 we considered Helium as "absence of Nitrogen", a good first approximation from a Nitrogen trimix meterLoading point of view, but not technically correct. So, in r10 we are - finally - taking Helium into consideration into our new decompression algorithm.
For the inquiring minds, we are using the data presented in Eirk Baker 's "Understanding M-values" paper.

While adding He, we decided to design an improved version of our current Nitrogen Loading Meter .... and voila', the new Trimix Loading Meter was born.
With the TLM You can track body absorption of both Nitrogen and Helium for each of the 16 theoretical compartments. Also, each compartment has now a new color coding scheme telling you if it is on-gassing or off-gassing, and if it is OK, in the warning area or in deco.

If you dive Trimix you definitely want to use this tool !
r10 candidate
To be released early May
It is almost time again for a new release .... or at least a partial one.
We are planning to release early May the "r10 candidate" ... what this mean is that for some time (probably a month) you will have the option of using either the existing r9, or to download the r10 candidate ..... and help us debugging it.

r10 will have several new features - the biggest one of which, from our point of view, is the use of the LUA scripting language .... check out Sandy the Great White Shark for an example of its use :-)

Also, with r10, in addition to Exploring, Learning and Playing we will now be able to add "MISSIONS" to the simulator .... the first one will be to rescue a diver entrapped in a wreck ..... what are you waiting for? The clock is ticking and the diver is running out of air ......
