Anyone know where I can find a copy of the latest version of Pro-planner?

Nope not there, I tried that

Same here I can't find it and VR don't give it to you with the comps anymore, only if you buy a kit or something.

Is this what you're after?

I've just downloaded this and had a play, have to say I'm not all that impressed...

Have you looked at VPlanner as an alternative? You can download it on trial to see how you get on, then pay for a license if you decided it's OK... if you don't license it, it will continue to work, but the dives you can plan are limited (no trimix and limited deco options AFAICR)

Your deco gas is limited to 50% or below.

Just downloading Pro Planner now. How long has it been free? I am sure it used to be expensive to get when I last looked.

Ah, just discovered that the software is using the same algorithm as their new computer the VRX. Now that looks nice, just emailed to see what the price is. You got one yet BK?

Many thanks Stu, just the job, now lets have a play with it, I have V planner, and just wanted to see the two side by side

No prob, I'd be intrigued to hear what you think....
