The Aeromic Black Zipster Pouchbelt is an adjustable 96cm-length neoprene belt. It's ideal for the "really sweaty" Instructor"!
Here's how and why. Disconnect the microphone and feed the plug into the Zipster through the slit at the bottom of the pouch. Plug it into the pack, turn on and test. Then put the transmitter into the vertical pocket upside-down and zip it up. This seals off the top of the pouch effectively solving any sweat problems.
In right way up use, the double zipper secures the battery pack to your body. It gives you easy access to Power on/off switches positioned on the front face or a side edge. You can also order an adjustable 50cm Black Belt Extender for $10.00
