This is a very different kind of soaker. The pump is an air pump, and the primary nozzle operates off the air pressurized reservoir. However, once the air pressure reaches a certain amount, a valve opens and water begins to fill the firing chamber. That chamber that you see on the top half operates the “secret strike” nozzle only.
If this was really any sort of secret, it would be a bad secret, because the “secret strike” nozzle is actually just a fan blast. This is annoying, because at some point – and you won’t know when – you will be feeding water to pressurize your almost entirely useless fan nozzle. You’re pretty much just wasting valuable ammo at this point.
The fan blast is activated by pushing down on the big orange button on top of the blaster. It can do a lot of soaking at close range, but because it’s a fanblast it’s not all that powerful. A larger nozzle, riot blast, or one of the spray settings found in the Monster series would be more effective. I made a shower nozzle out of mine and it’s a lot better. When you drain the firing chamber for the fan blast it instantly pulls in more water from the reservoir. This means that the last shot you take will have to be the fan blast.
Lastly, there’s a reason why these things are so rare on eBay. I have never known anyone to own a Secret Strike that didn’t eventually break. This is an early Max D gun, so the spring that connects the nozzle to the trigger is way too weak for the amount of pressure being placed upon it. There are much better options available if you’re looking for a blaster this size. I’d personally go with an old school XP, like the 55, or 65.
