FIRING ANGLE LIMITATIONS
Thanks to the natures of the CPS-technology, these weapons do not have any firing angle limitation. They are, however, still limited on their filling angle when pumping.

PRIMING BEFORE USE
Since all CPS weapons have a separate pressurized firing chamber based on an elastic force, air is not needed and can reduce the amount of water available to launch at one's foe. Before engaging the enemy with a newly filled CPS-based blaster, it is best to pump up the firing chamber part-way, then fire upwards to clear air from the firing chamber. This process should be repeated a couple of times until no more air is being expelled from the blaster. This primes the blaster very well and results in better soak-times in general.

MAXIMIZING USE
Since all CPS weapons have a separate pressurized firing chamber, one way to get an extra shot is to fill the tank first, pump to fill the firing chamber, then top off the tank. This will give one extra full burst, a definite plus especially considering how fast one can empty the blaster due to their increased firing rate.
When first filling the pressure chamber, some air may end up within it, resulting in a frothy stream when firing. To reduce/eliminate unwanted air from the firing chamber, pump up the chamber, point the CPS directly up, shake, and fire until a nice, solid stream is produced. This primes the weapon for use.

Cheap Trick: If one is almost out of water and is being pursued, one can fill the firing chamber with water, then unscrew the reservoir's cap and shake the blaster upside-down as if to say that one is out of ammo. If one's foes are a little too presumptuous, they will approach you without fear which is when you can, surprise, unleash a full burst of water onto them. Unfortunately, this trick usually does not work for veteran water warriors or those who have already seen it done.

CONSERVE WATER
CPS-based weapons use up their water at a ridiculous rate. As such, one can easily empty one's entire water reservoir before those air-pressure based systems finish squeezing off a second shot. Definitely avoid using full firing chamber bursts unless the soak is guaranteed. If applicable, switch to a lower nozzle setting when one's water reservoir is running low.

CLEARING WATER
CPS-based weapons tend to trap a good amount of water in their CPS-firing chamber even after the initial pressure is released. If the blaster is not to be used again for awhile (i.e. more than 24 hours), it is best to ensure as much water as possible is removed from the firing chamber. The reservoir should be emptied and then air pumped into the firing chamber. When pumping, hold the blaster upside down to force any residual water from the pump into the firing chamber. Once a few pumps of air have entered the firing chamber, point the blaster with nozzle aimed at the ground and pull the trigger. Repeat this until little or no mist is ejected. On blasters which do no pump air (some of the CPS series has some peculiar air/water valve), hold the trigger down while pointing the blaster downwards and pumping. The less water remaining in the firing chamber means the less likelihood of mildew or other "buggies" from gumming up the blaster.
