Day 2 – TDI Decompression Procedures at HTMS Chang ⚙️🤿

Today was all about stepping beyond limits.

On Day 2 of our TDI Decompression Procedures training, the team completed their first real decompression dives at the famous HTMS Chang wreck — and absolutely nailed it 💪

From precise gas planning to controlled ascents and staged decompression, this is where recreational diving ends… and real technical diving begins.

You could literally see the mindset shift underwater:
👉 More focus
👉 More discipline
👉 More awareness

And yes… once you experience your first planned deco stop — there’s no going back 😎

🌊 Why does a BCD inflate by itself during a dive?

It happens more often than many divers think — and in most cases it’s not dangerous, but it can definitely be confusing underwater.

In our new article we explain:

✔️ Why a BCD can start inflating on its own
✔️ The most common causes
✔️ How to stop it during the dive
✔️ What you should check after the dive

Understanding your equipment is an important part of becoming a confident diver.

Read the full guide here:

Safe diving starts with knowledge. 🤿

A simple guide for divers: stay calm, disconnect the LP inflator hose, control buoyancy manually. Learn how to prevent and handle a self-inflating BCD.

Today we explored:

⚓ HTMS Chang – powerful as always. Massive schools of fish around the wreck, light playing through the structure, that deep blue atmosphere you just don’t forget.

🚤 Dive Boat Safety – What Every Diver Should Know

A dive boat is not a party platform.
It’s a moving dive operation.

After thousands of dives around Koh Chang, we see the same small mistakes again and again — and most of them are avoidable.

✔ Equipment chaos
✔ Last-minute setup stress
✔ Wrong weighting
✔ Poor entry timing
✔ No awareness of boat procedures

That’s exactly why we wrote this new article:

👉 Dive Boat Safety – What Every Diver Should Know
https://changdiving.com/en/posts/straight-talk/dive-boat-safety/

Whether you’re a beginner or an experienced diver — good boat behavior makes the difference between stress and smooth professional diving.

Small habits. Big impact.

See you on board.

🌊 The last days around Koh Chang have been absolutely stunning!

From the colorful reefs of Hin Raab North, the relaxed coral gardens of Koh Yuak, the vibrant marine life at Hin Haap South, to the fish action at Blueberry Hill – every dive had its own character.

Crystal clear water, healthy reefs, schools of fusiliers, snappers, batfish and so much more. Koh Chang never disappoints.

Today we enjoyed two beautiful dives at the HTMS Chang — and the ocean was playing games with us.

Above the wreck, clouds were drifting back and forth, and underwater it was pure contrast:
one side crystal clear, the other suddenly 1 m visibility — changing every 10 minutes.

This shifting light gave the wreck an absolutely spooky 👻 and mysterious atmosphere, like diving through different worlds on the same dive.
Add to that huge amounts of fish, circling and hiding inside the structure…

✨ Pure underwater magic. ✨

Even on a cloudy, dark day, the ocean gave us pure magic 🤿✨

Strong current, crystal-clear visibility, and huge schools of mackerel, barracuda, yellow-back fusiliers and snappers moving like one living organism.
Challenging conditions, but exactly the kind of dives we love — dynamic, alive, and unforgettable.

That’s Koh Chang diving:
moody on the surface, breathtaking below 💙

🐋✨ UNREAL MOMENT AT THE HTMS CHANG ✨🐋

Today’s dive at the legendary HTMS Chang wreck turned into something truly unforgettable.
A whale shark joined us and stayed around our divers for almost 20 minutes — calm, curious, and absolutely majestic.

No rush. No stress.
Just pure magic as our divers floated in silence, watching one of the ocean’s greatest giants glide around us. Moments like this are the reason we do what we do 💙
