A Brief History of Super Soakers
This page is here to help out those of you who are not familiar with Super Soakers, or who have only become so recently. This will cover the major innovations and developments in the Super Soaker line, and should help you make sense out of some of the tactical scenarios on this site (which refer to weapons by model number). Everything is being sacrificed here to brevity, so anyone with a deep interest should look for a more informative site. Also, I myself am a bit sketchy on some of the details, so please forgive (and report) any minor inaccuracies.
The idea for the Super Soaker was originally developed by an aerospace engineer. They function by air pressure; the user "pumps" air into the weapon to pressurize it, and pulling the trigger releases the pressure the fires the weapon. This was a dramatic improvement in range and power over previous squirt pistols while allowing much more mobility and versatility than dipstick-style models (long tubes that expand to fill with water and fire based solely on the user's arm power), and became popular rather quickly.
The original base model was the Super Soaker 50, and the noteworthy weapons added to this were the 25 (which fit into a small belt holster, the only Super Soaker ever to do so), the 100 (bigger than the 50, with a separate pressure chamber), the 200 (bigger still) and the 300 (backpack). Several other products were developed, including some smaller Super Soakers, but none of these ever became well-known.
A few years later, Larami (maker of Super Soaker) released an "Xtra Power" (XP) line of weapons. The previous line eventually picked up the unofficial title "Classic Series" (CS) in some circles, while others prefix the number with the abbreviation SS (Super Soaker). Although the first XP line included several weapons, only the larger ones seem to be of major repute. These include the XP 105 and XP 150 (based on the 100), and the XP 250 (based on the 200). These larger versions were sturdier and more powerful than their earlier counterparts, and some are still in use today. The line included an XP 35 and XP 65 comparable in size to the 50.
Later Larami released two "XXP" weapons, the 175 and 275. These were new versions of the 150 and 250 whose primary enhancement was the fact that they each had two barrels instead of one. Around the same time and in the same rather strange mood, the XP 85 was released, which featured three barrels (two of which could be rotated up to ninety degrees to the sides) and broke rather easily.
The next big change came when the Constant Pressure System (CPS) 2000 was introduced. This uses a different means of storing pressure in the weapon so that whether you're at 100% or 10% of maximum, the weapon still has the same range and fires at the same rate, whereas earlier weapons only have maximum range and power at maximum pressure. The effective pressure was "constant." In addition, the weapon has the largest nozzle of any Super Soaker ever and spit water out with tremendous force (the weapon has since been discontinued, allegedly because it was a safety hazard). The primary drawback is that it required a LOT more pumping time per shooting time than any Super Soaker had in years (although may be fairly close to some of the original line) because it used water up so fast. Nonetheless, this weapon became extremely popular.
Following up on this success, Larami released CPS 1000, 1500, 2500, and 3000 when the 2000 was discontinued. The 2500 was about the same as the 2000, although the nozzle was adjustable (and its maximum size a bit smaller). The 1000 and 1500 were smaller versions that were a bit more economical in water usage, and the 3000 used a backpack reservoir like the early 300 had. Supplementing this, a new line of XP weapons was released, consisting of the XP 20, 40, 70, and 110. The 20 and 40 were smaller than the original 50, but more efficient. The 70 was a small version of the XP 105, and the 110 was a replacement for it.
Packing their enhancements closer together, Larami quickly released a new line called Super Charger (SC). These weapons came with a special hose hookup that filled the weapon more quickly and automatically pressurized it to maximum; in addition, they used CPS technology (constant pressure), although their power was closer to the XP line. Thus were born the SC 400 (comparable to the XP 70, but without a separate pressure tank), SC 500, and SC 600 (closer to the XP 110). Also of note is the SC Power Pak, which was a backpack weapon, but could only be filled up at a super charger station because it stored ALL of its water in a pressurized state, meaning you could fire your entire store without a break.
The next year, Larami made new additions to all their lines. New versions of the 20, 40, 70, and 110 were made, adding 200 to each of the numbers to make them 220, 240, 270, and 310. New versions of the CPS line were made in the same style (1200, 1700, 2700, 3200), and the new CPS weapons were given Super Charger capacity. Super Charger got an upgrade to the Power Pak called the Big Trouble, as well as a "Triple Charger" with three separate water tanks that snapped on and off and each could store water pressurized. Two entirely new additions, the Monster and Monster XL, were also released (apparently Larami was running out of ideas by this time), which had super charger capacity, a constant pressure system, and were REALLY BIG. That was the year 2000 line.
I haven't looked at the 2001 line yet, but I've heard that the Monster was renamed to the Mons
