Silent World is the largest and most experienced rebreather dealer in the Pacific Northwest. We are on the cutting edge of rebreather technology: Craig, our store owner, was the first (and for a long while only) instructor in the Pacific Northwest for the Evolution rebreather, and is currently the NW center for training and sales of the KISS line of rebreathers. Silent World sells and services Inspiration and Evolution closed-circuit rebreathers, and the KISS closed circuit rebreathers, including the new GEM semi-closed rebreather.  And, of course, we train divers to use these rebreathers. Silent World's training includes over 20 hours of practical academic training, hours of pool sessions, and at least 8 open water dives.

Instructor Craig Willemsen, with over 15 years experience diving and teaching rebreather divers, conducts our rebreather courses. Craig has over 2500 logged rebreather dives all over the world, come learn from one of the best!


Why all the training? Our goal is to have you "over-learn" the basics so you are completely comfortable with your rebreather. We go over and above the minimum training standards required by the certifying authorities.

AND we offer rebreather-friendly dive trips for like-minded rebreather divers!

 

Wondering whether rebreathers are the next logical step for you?  We've set up this guide to help you decide. Benefits of Diving a Rebreather Longer Bottom Time.


Deco Efficiency

Imagine diving for 60 minutes at 100 feet with no decompression time. Or 90 minutes at 65 feet. Or two hours or even four hours at shallower depths. Rebreathers reduce the nitrogen out of the air you breathe, reducing significantly your nitrogen load that leads to decompression diving, longer surface intervals, and, at worst, decompression sickness.  Your exhaled gas isn't released into the surrounding water. This means you aren't venting bubbles. Loud bubbles. Clouds of bubbles. This means you are diving silently. That silence, and the lack of scary random bubble clouds, allows you to get eye to eye with shy marine life that would usually hide upon hearing you. Most professional dive photographers are using rebreathers.

A Silent World

Because your exhaled gas isn't released into the surrounding water, you make no bubbles. No noisy bubbles. No clouds of bubbles to get in your viewfinder while you snap a picture of that elusive splendid toad fish. In other words: no holding your breath while you wait for that drum fish to just stop spinning so you can take its picture.

Additional Warmth while Diving

The air you breathe with a rebreather is warm and moist, rather than cold and dry on open circuit. This keeps you warmer throughout your dive (your body doesn't have to expend energy to heat the air you breathe) and prevents dry cotton mouth.

Lighter Weight

Less Weight to Carry Around Because a rebreather replaces the standard scuba cylinder and BC, it is often much lighter than a typical open circuit setup.

Reliabilty

Silent World only offers rebreathers with a proven safety track record. We only offer rebreathers that are built by companies with excellent long-term reputations.

Fun!

You really can interact with more underwater critters because you're diving truly silent.
