Scuba Tank vs. Tankless Hookah Diving: The Complete 2026 Comparison
Cost, bottom time, depth, safety and logistics — an honest, side-by-side look at when a surface-supply system beats a tank, and when it doesn’t.
How Deep Can You Go With a Hookah Diving System?
Rated depth vs. tested depth, why hose length is not depth, and the no-decompression limits that still apply.

Never Hold Your Breath: 3 Rules for Your First Hookah Dive
The three non-negotiables that keep first dives easy, safe and fun.
Master Neutral Buoyancy on a Surface-Supply Line
Weighting, trim and hose management — how to hover like a pro while tethered.

Spearfishing on Hookah: Where It’s Legal (and Where It Isn’t)
Many regions ban spearfishing with any breathing apparatus. A country-by-country primer.
Drifting the house reef at golden hour
Second week in Dahab. Rolled the S6 off the shore steps at 16:40 and followed the reef edge north. Four lionfish, a hawksbill and one very curious napoleon.
Pre-regatta hull scrub, 3 boats
Three keels, two props and a set of anodes before lunch. Used to need two tanks per boat.
Quarry skills day — trim & hose management
Practising hose routing around the platform and hovering at 10 m. Cold, clear, and very calm.
Lobster mini-season opener
Bag limit before noon, checked every ledge twice. Measured carefully, released the shorts.
Mussel raft inspection
Routine line check on six rafts. The anti-choke valve really does smooth breathing when you’re working.
First dive without a tank!
So much quieter than I imagined. Spent the whole time with a cuttlefish.
Blue Hole wall to 26 m
Stayed within NDL on the computer, slow ascent with a 3-minute stop. The S77 floats sat steady the whole time.
Sardine run, Moalboal
Millions of sardines a few metres off the wall. Floated the S7 from a banca and stayed with the ball for 90 minutes.
