The artic shock's pump stem is shorter than other models of its size but this gun still packs a good punch. This gun has one resevoir. The top part of the resevoir is just the back blue chamber which is connected to the bottom resevoir by the handle, so when you load water through the top part, it just flows through the handle to the bottom part of the chamber until the water fills up to the top part. The bottom chamber noticebley has a larger opening this cap is tethered to the gun. inside is a "removable core". This core has 2 parts, a sleeve, and a sort of icicle pop stick. You'll remove the stick part, fill the sleeve with water, insert the stick into the sleeve, then freeze. Remove core from freezer, separate stick from the sleeve and you have a icicle pop on a stick. You then place this "icicle pop on a stick" into the core chamber and close it up. Then load with water from the top part of the chamber. So see the water is cooled by simply by being around the icicle, which is about 6 inches long and 2 inches thick.(or you can just add ice). The arctic shock takes about 20 pumps to pressurize 100%, and is based upon air pressure technology. I don't know for sure if there is a separte pressure chamger for this gun, however just listening to it while I pump it, it sounds like it, and looks like the blue part behind the nozzle could be a separate pressure chamber. The resevoir holds 40oz. I don't know if the ice core is effective at cooling the stream I havent tried it yet, I figured the only way to truly test that would be under ideal (summer) conditions. The overall balance of the gun feels good and I would rate the power at a little better than the hydroblade.

But how can he not be sure if it has a seperate pressure chamber or not?

Not sure why, but I emailed him back anyhow on an almost fool-proof check: pressurize the blaster and open the reservoir cap. If air/water comes out and the soaker can no longer shoot, no separate pressure chamber. This test works for all soakers with the exception of the Max-D Secret Strike since that one uses both.

Edit: from Ray:

I tested the arctic shock by pressurizing the soaker then opening it. No water came out and it can still shoot. So as expected the blue chamber behind the nozzle must be a separate pressure chamber. The triple shot doesnt have a separate chamber.
