If you have a basic nitrox card, you still should be able to get EAN25 with it. If you have a nitrox computer, you should be able to dial in EAN25. You will find this mix significantly better than air is in the range of 100 to 150 ft.

You have to draw the line somewhere.

Sure you could drop down for a spike dive and a quick photo to 190 ft for 5 mins per the USN air tables. But you ultimately need to draw the line somewhere.

I'm not telling you how to dive. Just offering you knowledge about what I have learned as well.
