Shopper  Why Did You Choose This?
DAVID B  Purchased as a backup mic. for interviews and reporter stand ups. Works well.
Shopper  Is this a good mic to use with the Sony PD-170 or other HD Cam with a XLR connection? What is the radius of the audio it will pick up? Ron T Gainesville, FL
HOAG L  It will work well with a PD-170 and other video cameras, both HD and standard. It is a lavalier mic that pins to the shirt, so it's designed to be used at close range. It produces really high quality sound.

DAVID B  This is wireless if you plug a wireless transmitter into it. The microphone is intended to be wired, using a 3pin XLR cable, into camera mic input or other recording device.
