Brand: Genesis
Located in: Essential Equipment, Regulators
Innovation at its best is the way to explain the function of the Genesis GS2000 Regulator. The first stage regulator incorporates Genesis Dry Air Demand (DAD). This simple yet unique design has a flow-by piston that mechanically balance theair of the first stage ensuring excellent breathing characteristics at full or low cylinder pressures.

The DAD's function allows the regulator is increase the intermediate pressure ofthe 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. Built from marine grade chrome plated brass for long life with two HP Ports and four LP Ports for addition of gauges and LP accessories, this is one work horse first stage regulator.

The 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 (302) passivated (302) stainless steel demand valve lever. Breathing resistance is factory set for optimal resistance and the orthodontic mouthpiece allows hours of comfortable breathing without jaw fatigue.

I've used this regulator only 3 times, but it works great! When I was at depth the first time, it started to free flow but that was easily fixed with the adjustable knob.

This is an excellent regulator that can be used in all conditions. It can free flow at times on the surface but this is no big deal and is easily controlled. It also functions well at low depths and breathes easily. Best reg I have used so far!

Comments about Genesis Genesis "GS2000" Regulator GR450:

I got this as part of a package. The reviews made it seem like a good value. My friend and I both bought the same regualtor for a trip to Cozumel. We're both rather new and had been using rental equipment. The rental stuff at times was not that good so we decided to make the plunge. We both had a little problem with the free flow on the surface. The switch, + and - is not intuitive. We both require reading glasses and the little symbols are hard to read. I tried pushing the switch to both settings hile on the surface but did not notice any change. I had a free flow on my first dive but it didn't happen again. My friend got afree flow at the end of 2 dives. Not a big deal, just an annoyance. We both found the regs easy to use. As a new reg owner I would have liked to have some instruction on assembly, how much to tighten the connections, etc.

Comments about Genesis Genesis "GS2000" Regulator GR450:

Just finished a one week trip in Bonaire and used my Genesis GS2000 for the first time....I've been diving for over 30 years and this is a GREAT little regulator; super performance and easy breathing down to 137 ft. The diver adjustable parts on the second stage are easy to use.

Great regulator, esp for the price. I highly recommend it!!

In my buoyancy check on the beach, the chrome piece that keeps the circular bladder in place uncoupled or unscrewed while going under, and got lost in the water. [...] it should be noted that I could NOT repair the first stage on the island, so I am now carrying a replacement for those strange conditions.

Comments about Genesis Genesis "GS2000" Regulator GR450:

Good reg feels good breaths easy.

I haven't noticed a difference between surface and dive mode.

So far the only con is it free flows easy. What I usually do when I take it out of my mouth is set it to surface mode and turn up the resistance a bit.

Also I remember reading in the instructions that you should not take it past 100 and something feet?

Was skeptical due to the price, but not after using it - this reg breathes very easy, the free-flow switch works very well - none at the surface.
My wife has an Oceanic GT3 DVT and I experienced NO noticeable difference in breathing thru my GS2000 and her GT3 - except hers was more expensive!

Comments about Genesis Genesis "GS2000" Regulator GR450:

This is a solid regulator with a great design, the adustable feature is nice. First time I used it I got a little cottonmouth in the pool. However on dives it hasn't been a problem. D.A.D. keeps the 1st stage clean, and the second stage nevr freeflows even when getting into the water. Over a solid regulator at a pretty reasonable price.

Comments about Genesis Genesis "GS2000" Regulator GR450:

I am a rec diver, I have used this reg in several warm water environments.

I have really fallen in love with my GS2000, especially considering the price. It's extremely easy to breathe out of, and the user adjustment makes a noticeable difference at depth.

I almost spent 3x as much on an Atomic but am glad I didn't, as the GS2000 has been more than great so far.

Comments about Genesis Genesis "GS2000" Regulator GR450:

Very nice reg, took some time to work out the adjustable knob, but even without adjustment breathing was easy. It did cause a little jaw fatigue when I first used it, but after 9 dives I didn't have any problems. This reg was reccommended by someone at LP, and I ended up diving with someone that used the same reg; both people loved it.

Comments about Genesis Genesis "GS2000" Regulator GR450:

Very nice regulator, way better then any of that rental stuff(which is still not cheap). The adjustable function works very well, you can adjust the reg. so the breathing is effortless. Little switch on top is too small, but regulator, if adjusted well, does not free flow so I do not use it.I called the company they confirmed that the reg is Nitrox ready.
The best deal ever, I think!

bought it with Octopus days before my trip to the bahamas. Does NOT included BCD hose, so be sure you order one if you need it. I replaced a used reg that had water infiltration issues going deep; was able to go 120 feet under without issues.

Service & Delivery comments:

I was VERY impressed with the service. When I had to get a BCD hose, they overnighted it so I had it the day before I was flying south

Comments about Genesis Genesis "GS2000" Regulator GR450:

This is a good first regualtor. The only thing I do not like is the little switch on top. It has two positions. One for diving and the other for, I believe, maintenance. OK, which is which? I don't recall. There should be a better indication on the switch other than + and -.

Comments about Genesis Genesis "GS2000" Regulator GR450:

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.
