Do I need Nitrox?

Yes I'm Kidding
Do not dive depth 25 ft 120 minute SIT 1 hours ...Insane:shakehead

You're kidding right? :shakehead

I have been doing some beach dives lately. My typically dive with the following profile:

~ 2hrs with a max depth of ~20-25ft
~ 1 hr surface time
~ 2nd dive at 2hrs with a max depth of ~20-25ft
~ Using tanks (80 cu ft) with air

My computer shows no problem with my nitrogen level (Aeris Atmos AI). I recently decided to check my tables and per NAUI's recommendation - for dives less than 40 ft I use the 40 ft table which indicated I exceeded the limits.

Should I switch to Nitrox to be safe?

Any feedback is appreciated

Thanks

Have no clue about your NAUI materials,,,,,but with your indicated dive profile you are just fine on AIR.

Used Air is fine but SIT I hour is too short :shakehead

Too short according to whom? Run that dive through V-Planner, decoplanner, GAP, Nautilus, and tell me what you get back...

Ok, well my padi table says it's fine. So who's right? You or me?

I used Decoplanner

Ok, well copy the output from decoplanner and show us what the mandatory deco is from the second dive...

NAUI DIVE TABEL 12m - 40m
PADI DIVE TABLE 10m - 42m

If you go for 18m depth

NAUI TABLE is 55 minute 3 minute safety stop at depth5m
PADI TABLE is 48 minute 3 minute safety stop at depth 5m

Not much different from NAUI and PADI dive tables
