pakman:but some may argue best mix for 150-155ft to include some helium....
I would be one of those guys... Sorry to be a downer but I wouldn't do this dive on Nitrox...
The 25% has got to be Helium The END of 25 EAN is 150, MOD of 150 would you plan a dive that close to your MOD? I give my MOD at least 10 ft... more like 20 usually
Like Andi says be careful
