Range: As far as you can throw it
2 x Sonic Distractor spheres (1 black, 1 grey - 4 different sounds apiece. See the video for the different sounds)
1 x belt clip/holder
This is an interesting little gadget from Spy Gear. Relatively inexpensive (some stores have them on clearance), and in the right scenario/gametype, maybe these would be of some use if you have a particularly sneaky style of play.
2 spheres, and you hold the button down to trigger a timer, and after a few seconds the distractor makes 1 of 4 noises. If you can remember the sequence of the noises on each sphere, you can readily select which one you're using (birds cawing, a cat yeowling, laser blasts) but in some instances maybe just a sudden noise of any kind would be enough).
Maybe even a game like this:
I didn't whip these around on concrete (also I would NOT suggest throwing these at people) so I couldn't tell you how durable they are from a dropped height. I believe ideally you would roll these into position to use them, though rather than throw them around. They are of a hard plastic construction so they would definitely bounce around. Still, the amount of sound effects available, the compact build, included holster, and easy to use button are nice little touches.
You might even find these on clearance at the moment, so if you have the right group and location, these could be a handy fun roleplay (spy vs counterspy, thief vs guard) element for your game types. What do you think? Would you try them?
