I recently did Sea Trek during a visit to Cozumel in the Caribbean Caribbean, at the Chankanaab nature park. This is a favorite sport in the Caribbean islands. The tour begins at the end of the pier, where your guide will give you some brief instructions about the rear hand signals (including how to signal if you are frightened and want to return to the ground). ) and how to get into Trek Trek’s diving helmet water (answer: slow).
Then it’s time to put on the device, which is like a space helmet that sits right on your shoulder. Out of the water, it’s really heavy, so you don’t want to linger on the dock. (You don’t get any other equipment, so just wear a bathing suit.) Once you’re in the water you basically just sink to the bottom, and voila, you’re standing underwater!
A tube from the surface provides air into the helmet, and the pressure holds water out. For breathing purposes, this works very well, and large transparent bubbles around your head help Prevent you from feeling stuffy. It all sounds pretty stupid, unless you decide to take off the helmet on purpose. You need to stand up straight, of course, but it’s hard to fall into the water.
The drawback of this system, however, is that the sound of the air being pumped into the helmet is huge, so you don’t exactly get a serene, Little Mermaid kind of experience down there. And, even underwater helmets make awkward movements, and you still feel the weight of the thing on your shoulders.
Once the initial thrill disappears, that’s also the problem – at least in Chankanaab – that’s not much to see or do while you’re at the bottom. You really can’t go far from the pier, your time below is limited (less than 10 minutes), and the seabed just outside the beach is quite barren – sand, a few boulders, some pilings, and a regular fish floating by.
Our guides did their best to make things interesting – including scattering food to draw fish closer – but that’s not it. Certainly not for $ 75-100 you will pay for experience.
