Beautifully machined. Beautiful performance. And it keeps the oceans beautiful, too. As the first “Green” regulator ever designed, the S2 is made of a special grade of 316 Stainless Steel and it is 100% recyclable. The S2 offers superior corrosion resistance and does not require chrome or nickel-plating processes that create environmental concerns.


Suitable for sidemount regulator up to EANx40 with white color scuba regulator to choose from too. (There are sidemount scuba regulator set and recreational scuba regulator fullest for sale)


At HotDive, it’s all about the metals. The 316 Stainless Steel used in the S2 has twice the strength of brass with the durability of Titanium. It delivers virtually the same corrosion resistance as Titanium at a lower price. Environmental experts have classified Stainless Steel as the Green metal of the future because of its strength, ability to resist corrosion, and ability to be recycled. The HotDive S2 is designed to breathe effortlessly at atmospheres below the surface while helping preserve the atmosphere above.


Environmentally conscious topside natural breathing at depth

The first stage is beautifully machined from a special grade 316 Stainless Steel that is twice the strength of brass with corrosion resistance approaching Titanium. The use of Stainless Steel means we are doing our part for clean air when divers are out of the water. 

Great Looks and feeling

  4. Jasmine Smith

    fast delivery and great gears

  6. Philip C

    excellent quality and price, fast shipping

  7. Flenn W

    White color are really unique and i love it.

  8. Dejan M

    Breathing is just as easy compared to the balanced Apex regulators I trained on. Compact 1st stage and the 2nd stages are small enough for travel on the plane in my carry-on luggage. Very tough construction and both sets I purchased have been flawless on multiple dives down to 30m+

  9. Carlos S.

    This is a great reg and octo set for a good deal. High quality too. I bought the din version as I prefer the option to run din or yoke. Most of my tanks have yoke adapters as I find them easier to mess about with.
