Whistlers with Silver Comet are an effective 15mm audio-visual deterrent. These whistlers travel 250-300ft while continuously whistling through flight, shells also contain sparkling tracer for added effectiveness. The alarming sound results in an immediate fear response in birds and animals. Margo Supplies also carries regular Whistlers without the Silver Comet effect in addition to the Pyro Screamers with Silver Comet.

At Margo Supplies, we recommend using a combination of audio and visual scare products for the most effective animal deterrence system. We carry a variety of 15mm cartridges that include audio and visual scare elements.

Compatible with 15mm launchers (sold separately).

6mm blanks are required for firing (sold separately).
