Pinpoint ultrasound from up to 300 feet (100m) away using the PowerBeam 300 extended range attachment along with the CTRL UL101 receiver and headset. The ultimate add-on for your ultrasound listening device.
The PowerBeam 300 is a parabolic accessory originally designed to test high voltage insulators and transformers from a safe distance with a high degree of accuracy. The PowerBeam 300 can accurately pinpoint sources of ultrasound within 1 degree off target from up to 300 feet (91.44 meters) away.
The PowerBeam 300 accurately pinpoints source of ultrasound to within 1 degree from center and improves the sensitivity of the UL101. The "PB300" was originally designed for the indication and location of corona discharge and arcing on medium/high voltage transformers.
The PB300's ability to pinpoint ultrasound is very useful when finding compressed air/gas or steam leaks in pipes located on high ceilings. There is no need to get a ladder or scissor lift.
