Divers, I came across an opportunity to purchase two used sets of Xstreams. I don't know too much about these regs except they do have a good reputation; hence my question on this forum. Based on the 6 digit serial number stamped on the first stages it looks like the regs were built in 2002 and...

So DivePal allows you to specify your own gradient factors for dive planning/playing. But it takes it one step further where you can specify the M values for each compartment of the Buhlmann ZH-L16 model (see screen shot below; GF 100/100). To validate this functionality I tried to replicate a...

Using the DivePal windows software, can you enter in your depth and bottom time and the system generates a decompression profile based on the Buhlmann algorithm specified?

Dear Suunto divers, I don't own a Suunto but I have downloaded DM5 to play with deco planning module. They recently upgraded DM5 to include RGBM Fused 2 and I find it personally interesting to run different deco profiles to become familiar with the versions of RGBM. With regards to safety...

I thought I would ask first before doing the legwork myself. Has anyone compiled a table/spread sheet listing the different GF Presets by Manufacturer/Computer? More and more manufactures are offering dive computers with gradient factors. Depending on the level of customisation, they may offer...

For those of you who didn't notice the pop up when you started your Logtrak, Scubapro has issued a minor upgrade to the software. Notes included: History ----------- + G2 1.5 and G2C 1.3 support * Database migration to meet latest dive computer * User settings Symbols ----------- + added...

I watched @Dr Simon Mitchell presentation Decompression Controversies on Youtube for the umpteenth time. Around minute 33, he starts to discuss the problem with bubble model deep stops using gradient factors 20/90 as an example. He graphically demonstrates that while the fast compartment is...

Lately I've been watching episodes of Sea Hunt on YouTube. I've noticed that Mike always wears a particular brand of polo shirt. Is it a Fred Perry?

I do not own a G2 but I am curious. Has anyone made a table listing depth and NDL for each microbubble level? Including L0 that would make 10 levels of conservatism, I can't help think that with L9, a diver would only have to put his face in the water and be required to do a deco stop.:confused...

When the Scubapro came out with the heart rate monitor chest strap, I think it was a simple Polar T31 where you could not change the battery. In later years, it introduced a new chest strap where you could change the battery. In addition, this new chest strap could monitor your skin temperature...

If any of my assumptions below are inaccurate, please correct me. First, let me provide you with some background. I am a recreational diver and have never conducted decompression dives. I may train to deco dive in the future. My current Dive Computer (DC) is a Tusa IQ750 which employs the...

Hi everyone, For those of your who own a Tusa IQ 750 Element II, have you had any issues turning on your backlight? I changed the battery. In "U" (utilities) settings, I increased the duration to 10 seconds but pressing the "S" (side) button nothing. Does it only activate at depth? Its not a...
