About Nemo

Nemo is a compact dive system that supports 1 diver to 10 feet with a rechargeable battery pack that lasts over an hour. Air is drawn from the surface above the water and pumped through the air hose to deliver clean breathing air to a diver up to 10 feet deep.

Nemo’s custom-designed compressor is fully sealed and built to interact with saltwater. Patent pending Smart Reg™ technology enables Nemo to be the world’s smallest dive system and weigh in at only about 10 pounds.

Battery Powered

Nemo’s lithium ion battery weighs about 1.3 pounds and can be easily swapped for an additional 60+ minutes of run time. Recharge time is 3 hours or less. The battery capacity is less than 100 Wh (watt-hours) so it can be brought onto an airplane in carry-on luggage.

Patent Pending Smart Reg™

Nemo’s Smart Reg is patent pending and unlike any other diving regulator on the market, and it is what enables Nemo to be more portable and energy efficient than any other dive system on the market. Inside of the Smart Reg, a waterproofed sensor detects when a diver inhales and it then sends an electronic signal which triggers the compressor to pump air at exactly the time and speed that the diver is inhaling.

Nemo pumps only the exact pressure, volume, and flow rate that the diver needs at their particular depth which means it uses just a fraction of the energy of any other underwater breathing system.

Nemo Online Dive Training Course

Learn about diving techniques before Nemo Diving by taking the Nemo Online Dive Training Course, available for free to anyone at any time at This course was specifically designed for Nemo Diving with the help of experts in the field of diving. It is required that all users complete the course with a passing score prior to Nemo Diving.

Dive Flags

Dive flags are used to signal that a diver is underwater. The Red and White flag is used in the United States, Canada, and some other countries. The Alpha flag is used in most other countries around the world.

Always check the dive flag regulations for where you’ll be Nemo Diving and make sure to install the proper flag style so that boating traffic will steer clear while you are underwater. If you travel, you may find it useful to have one of each – choose “Both Dive Flags” from the drop down menu above!

Flotation Tube

Nemo has enough buoyancy to float in the water without clipping on the flotation tube for times when you are diving in the pool or other enclosed body of water. But whenever waves or boating traffic are present in your diving location then the flotation tube should be installed to provide Nemo not only 22 lb of additional buoyancy but also superb visibility.

The flotation tube easily inflates and deflates so that it packs away nice and small. Inflates by oral inflation. To attach the flotation tube, simply slide it onto Nemo from the top and clip the corresponding buckles together.

Heads Up!

Please have a look at our dealer map here for shops near you that might have Nemo in stock.

Nemo Backpack

Padded back support and shoulder straps for extreme comfort. Storage compartments inside are designed to organize your air hose, batteries and chargers, flotation tube, dive flag, and weight belt. There’s also a zip pocket for miscellaneous items like your phone and wallet and straps on the side to carry your fins.

OTS Spectrum Full Face Mask

The OTS Spectrum is a Full Face Mask that can be used with Nemo to eliminate the bite down mouthpiece of the Nemo Smart Reg. The Spectrum adapts to the Smart Reg by inserting the Smart Reg into the Spectrum and securing with a zip tie. With the Spectrum, users can breathe through their mouth or nose, with no need to bite down on the mouthpiece. The mask seals around the user’s face for extreme comfort and warmth.

Other benefits of the Spectrum Full Face Mask: no jaw fatigue, no dry mouth, double seal for a better fit, five point head harness and the option for communications systems. Add on the Spectrum GoPro Mount if you have a GoPro you’ll use to film your dives with Nemo.

    I am very satisfied
    my nemo works fine
    I would have liked a longer autonomy / for the battery
    But it is okay

    just a bad mark / for the charger connectors
    they are to the US standard /
    and does not work on European sockets
    (you should offer them as an option / or give a reference to buy them online)

    once this problem solved
    I was finally able to try nemo = it’s great
    light, easy to carry / for those who want to dive
    in shallow water / there is nothing better
