130 feet is not just deeper. It’s a different dive entirely.

There’s a version of you that hits 100 feet and feels completely in control. And there’s a version that hits 100 feet and spends the next few minutes quietly managing the fact that things feel slightly off — a little slower, a little heavier, a little less sharp.

That second experience is nitrogen narcosis. It doesn’t announce itself. It creeps in, and if you haven’t trained for it, you may not even recognize it while it’s happening.

Depth Changes the Math on Everything

• Your no-decompression limits shrink fast — at 130 ft you’re looking at roughly 10 minutes NDL on air
• Gas consumption increases with ambient pressure — the same breathing rate burns through your cylinder faster
• A rushed or panicked ascent from depth carries real decompression sickness risk
• Narcosis impairs judgment in subtle ways that become serious ways when the dive goes sideways

Built for Genuine Control at Depth

The SDI Deep Diver course doesn’t just give you permission to go deeper. It builds the planning discipline and situational awareness to operate down there with genuine control:

• Narcosis recognition and practical management strategies
• Gas planning specifically for deep no-decompression profiles
• Multi-level dive planning to maximize bottom time safely
• Controlled ascent and safety stop procedures at depth
• Emergency protocols when depth is a factor

Most New England and Great Lakes wrecks live between 80 and 130 feet. If that’s where you want to dive, be ready for it before you splash.
