No quad left behind!
HellGate FPV has developed a buzzer with a tiny built-in battery that literally gives it the power to sound an alarm for over 3 days.
In many serious crashes, your LiPo can be disconnected or ejected, and the buzzer you had depended on to locate your quad no longer has a power source. With this simple but ingenious innovation, HellGate has made this amazing tool to give you the confidence to fly farther than ever before, with the knowledge that you'll be able to find your quad if you crash. You don't have to worry about charging it either: it charges itself simply by being plugged in.
To disarm the buzzer after activation, simply connect and disconnect your flight pack quickly to hear the deactivation tone.
