CONSTANT PRESSURE SYSTEM SERIES: This is my personal favourite water weapon series. In 1996, the first generation CPS-class weapon was released, dubbed innocently as the CPS 2000. This marked the start of the 3rd Age of Water Weaponry. A minor oversight by Larami was their negligence in putting an age limit on these water blasters. The thick, potent stream unleashed by the CPS 2000 could make another's vision blurry if he/she took a direct hit in the face, even with eyes closed. Undoubted countless complaints went to Larami by angry parents who blamed Larami of making a children's toy that could result in serious injury. (Personally speaking, if those parents were doing a better job, the CPS 2000 would never have gotten into irresponsible hands in the first place, but I digress...) However, with CPS technology now unleashed on the market, Larami could no longer look back without fear of losing patronage.
In 1998, Larami released the rest of the CPS line, namely the CPS 1000, CPS 1500, CPS 2500 and the CPS 3000. Even now there is no other water weaponry available which can match the sheer output volume and tank capacity of the CPS-class water blaster.

General Notes: The smallest nozzle size on the standard CPS weapon is rated at 5x larger than those found on the XP-Series! All CPS weapons have a separate firing chamber which allows full strength shots even when low on water or only with a few pumps (minimal end trickle). CPS technology relies on a strong elastic rubber firing chamber which literally squeezes water out through the nozzle when the trigger is pulled. All CPS weapons come with a handy shoulder strap making it much easier to carry more than one. The water capacity for this series starts at 2.3 litres and goes up to the sadistic 8 litres held in the backpack of the CPS 3000. Despite having a fairly large payload, these weapons deliver water very quickly and will virutally empty their reservoirs before an XPer can fire off two complete shots. This, of course, means one needs to be more thrifty with water use when on extended trips away from a filling source. It also means one can drench someone more accurately and quickly than a water balloon during an all-out squirtfest. Currently, the only device to out-drench these weapons are hoses but those have limited range and, in the same amount of time, do not always fire as much water!

FULLY REVIEWED WEAPONRY
CPS1000: Excellent light field blaster. Can be used for high-yield surprise attacks as well as a heavier-style backup. Quick to pump and quick to drain. Relatively small and easy to carry. (Rating: 9.5)
CPS1200: Excellent light field blaster which performs just as well as its older brother. Can be used for high-yield surprise attacks as well as a heavier-style backup. Quick to pump and quick to drain. Relatively small and easy to carry. (Rating: 9.5)
CPS1500: Still my favourite all-purpose water blaster. Great for surprise attacks. Two nozzle setting for drenching or water conservation. Quick to pump and quick to empty plus a rather large firing chamber. Only slightly larger than the CPS1000 but packs a better punch. Great anytime, anyplace, anywhere. (Rating: 10)
CPS1700: Basically identical to the CPS1500 with the exception of colours. Two nozzle setting for drenching or water conservation. Quick to pump and quick to empty plus a rather large firing chamber. Only slightly larger than the CPS1000 but packs a better punch. Great anytime, anyplace, anywhere. (Rating: 10)
CPS2000: Once my favourite and still the most powerful. Bulky and gives a nice kickback when firing. Will even match a hose's yield (but not for very long). A little harder to move with and takes a lot to pump up the firing chamber. Great for use as a heavy backup (i.e. bazooka). (Rating: 9)
CPS2500: Modern replacement for the CPS2000. Three nozzle settings to allow to serious drenching, good soaking or water saving. Relatively small firing chamber for a CPS-class weapon. Still a good cannon and its size adds to the intimidation factor. (Rating: 8)
CPS2700: Though its number is larger, this blaster falls somewhere between the CPS 1500/1700 and the CPS 2500. Three nozzle settings to allow to serious drenching, good soaking or water saving. Good sized firing chamber and a reservoir to match! Rather heavy when fully loaded. (Rating: 9.5)
CPS3000: Heavy-duty heavy water blaster. Most amount of water capacity for any water blaster out there. 4 nozzle settings: 3 the same as for the CPS2500 + typhoon for close-range area drenching. Large firing chamber capacity, but questionable strength backpack. 8L of water is hard to run with so best used for base defense or heavy assaults with support. Takes a good amount of work to pump up the firing chamber. (Rating: 9)
CPS3200: Nearly identical to the CPS3000. Heavy-duty heavy water blaster. Most amount of water capacity for any water blaster out there. 4 nozzle settings: 3 the same as for the CPS2500 + typhoon for close-range area drenching. 8L of water is hard to run with so best used for base defense or heavy assaults with support. QFD can be used to fill backpack via hose. Takes a good amount of work to pump up the firing chamber. (Rating: 9)
