SVP SA-441 MAGNUM DUAL TONE SIREN 

This is my SVP SA-441 Magnum siren. This is an older model, unlike the Signal SA-441 that I posted a few years back. This model has the same features, however you'll notice the Wail will wind down longer than the previous Signal 441 does. This is definitely one of my top favorite sirens and I prefer this model more than the Carson SA-441 or the current Signal SS741MG. (Yes, the siren tones sound different.) ENJOY!
