The MK5 Thunderflash is a long-standing favourite for sheer noise. It produces a single, sharp report with no smoke or flash, purely a loud bang to startle and distract defenders or signal across a site. It's the sound of a busy CQB game.
It ignites by friction — you twist off the cap and strike it against the exposed fuse — with a short fuse delay before the report. At around 115-120dB at 10m it certainly makes itself heard.
It's a disposable device with a biodegradable body, slim and easy to carry in numbers.

Good to know before you buy
Strictly 18+ and only where your site permits report pyro. Strike, throw and keep clear — never hold it after lighting, and respect the safety distance given the noise.
