About Genesis GS2000 Regulator GR450

Innovation at its best is the way to explain the function of the Genesis first stage regulator. The first stage regulator incorporates Genesis Dry Air Demand (DAD). This simple yet unique design has a flow-by piston that mechanically balances the air of the first stage ensuring excellent breathing characteristics at full or low cylinder pressures. Balanced flow-by piston design, which is a "fail safe" mechanism, with a patented dry seal internal mechanism to keep the intricate components clean and contaminate free no matter what kind of environment you dive it in, constructed from marine grade chrome plated brass for long life and durability.

The DAD function allows the regulator is increase the intermediate pressure of the regulator without messy oils or grease as with more sophisticated designs. This added benefit makes the regulator virtually uncontaminated from the environment of salt, sand or chlorine internally, which makes it the choice of most repair technicians. The first stage is equipped with two 7/16" threaded high pressure (HP) ports and four 3/8" threaded low pressure (LP) ports for addition of gauges and LP accessories; this is one work horse first stage regulator. Tee - shaped design reduces regulator profile when mounted on tank minimizing opportunity to make contact with the back of the head. First stage has a high capacity inlet filter for smooth delivery of air to the second stage. The Genesis GS2000 Balance 2nd Stage delivers air effortlessly; its pre-dive/dive switch eliminates sensitivity when swimming through surf, jumping off the side of the boat, or fining in a current, yet allows high performance breathing when needed. Durability is assured with a non-corrosive ABS/Polycarbonate housing and a corrosion resistant passivated (302) stainless steel demand valve lever. Breathing resistance is adjustable for optimal resistance. The GS2000 2'nd stage regulator adjustment knob is unique in that once the diver finishes tuning the regulator at the surface, the second stage automatically compensates for changes in ambient pressure providing smooth and easy breathing from start to finish of your dive. The regulators orthodontic mouthpiece allows hours of comfortable breathing without jaw fatigue. Regulator comes with an owner's manual and is covered by a 24 month limited warranty.

The Genesis GS2000 Regulator GR450 is commonly used for Cold Water, Extreme Depths, Recreation, Warm Water and more. The Genesis GS2000 Regulator GR450 is most used by customers who consider themselves to be a Advanced, Advanced Diver, Beginner, Casual/ Recreational, Recreational Diver among others. The Genesis GS2000 Regulator GR450 is popular because customers like the following qualities of the Genesis GS2000 Regulator GR450: Adjustable, Comfortable, Effortless breathing, Nitrox Compatible.

Genesis (owned by Sherwood) is not a particularly well-known company. It's not one of the innovators (e.g., Aqualung, Apex, ScubaPro) either. But, they've made a great regulator in the GS 2000. I use the GS 2000 in the Puget Sound in a variety of cold-water conditions up to about 100 feet.

It has been a solid performer for me. It is environmentally sealed, an easy breather, and is a rock-solid performer at a sensible price. It takes abuse well and has the features I need to dive a fairly challenging environment. Maintenance is easy, parts are easy to get, and the regulator techs I've talked to all speak highly of the way it's made.

I'm no technical diver, but the Sound can be a challenging environment for scuba gear. But even in 36-degree lake water at altitude, it doesn't free flow or breathe rough.

I wish the venturi adjust was marked a bit more clearly, but I feel confident using it anywhere, any time.

This regulator is fussy and runs very wet. It has too many knobs and adjustments. It was difficult to find the sweet spot that would not allow sea water to enter my mouth or prevent it from free flowing.

    Comments about Genesis GS2000 Regulator GR450:

    Wife and I have had these 6 years, 100+ dives and have never had a problem. 57 - 80 degree water and deepest depth is 147' . They breathe easy and consistently except when you're on your back. I highly recommend a softer and more flexible hose though. After 5 dives a day for a week jaw fatigue sets in due to the hard hose and trying to look at everything. Otherwise this is a great problem free reg.

    Comments about Genesis GS2000 Regulator GR450:

    I have owned my GS2000 since 2001 (same reg as I just bought). I dove countless wrecks and have been diving the exhibits of Mystic Aquarium (Connecticut) for the past 3 years with this reg. I love it - it actually breathes better than my Aqualung Legend which cost twice as much. After 12 years and over 400 dives, the outer membrane of the purge valve tore and, though it still works, I figured it's time for a new one. Great reg though.

    Nice reg for the money, I like the adjustor however this reg does tend to free-flow easily which was a little annoying. Mouth piece is way too small for me and upgraded to a "seacure" mouldable mouth piece which was an awesome purchase, just came back from Sipadan after 16+ dive no jaw fatigue with "seacure"

    Excellent reg for the money however I found the mouth piece way too small and created a lot of jaw fatigue, have now replaced this with the secure hi flow mouth piece 11 fits really well but have not used as yet. Genesis reg is prone to free flow.

    Questions & Answers Powered by TurnTo®

    Questions about this item:

    Shopper  what is the predive lever off position on the regulator?
    DON D  This reg sux, don't buy it !!! I ended up selling it less than a year after purchase. It had serious tendency to free flow.
    SANDRA R  I own this regulator. I have dived with it numerous times. During my next to last dive trip, I started having problems with the octopus free flowing, maybe 1st stage too. Anyway, I decided it was time to have the regulator serviced. I just got back from Cozumel, where I used my newly serviced Genesis reg. There was no free flowing, and the regulator worked well.
    Shopper  Does the Genesis \"GS2000\" Regulator GR450 have a swivel on the second stage??
    NATHAN B  The 2nd stage of my GS2000 (mouthpiece) swivels around the air hose. The 1st stage (connects to the tank) does not swivel.
    manolis p  Is this Reg. 100% enviromen Sealed Piston ?
    Regina C  I am not that technical so I don't know the answer to your question. Perhaps you should ask a service technician from Leisure Pro. I do like this reg though and so far have not have any issues with it.
