While the Pulse Master's factory stats for the PC volume is supposely ~115 mL, I only measured ~100mL during testing. What I was surprised at was the force of the stream coming out of this blaster! While the volume is low, force is quite high. In fact, on its largest nozzle setting, the Pulse Master pushes out its PC in roughly 0.5 to 0.6 seconds (basically at the threshold of my ability to time the stream).
Unfortunately, on its lower nozzle settings, while the streams perform well themselves, there seems to be some backflow/leakage from the nozzle selector, resulting in a good amount of dribble out of the base of the blaster (the nozzle selector is actually mounted more securely within the body of the blaster). Perhaps a little tightening of the selector may help, but haven't tried it yet.
Reservoir volume is ~2700 mL (~90 oz.) giving one ~28 full shots from a fully-loaded blaster. With that sort of capacity, I'd probably end up leaving the blaster set on max stream. Sadly to me, the nozzle selection doesn't include a fan setting, but then again, a fan spray with low volume wouldn't be too impressive.
If I find the time, I hope to have a full review up by the end of the week, but we'll see how it goes. I'll also try to post up some internal pics as well soon. As Fox noted before, these blaster don't use ball-valves, rather they use good ol' pull valves for firing. They have a great linear design, basically having the nozzle in-line with the PC. Overall, I'm very impressed by this series and am quite optimistic about the future of stock water blasters!
