Polyvalent means that you can attach two radios to your headset. You may Tx and Rx using your 2 meter amateur (VHF) radio on the left earcup AND your aviation airband (UHF) radio on the right earcup. These configuration can be switched internally ... 2 meter radio on the right earcup and aviation radio on the left earcup. Both earcups have INDEPENDENT volume control knobs and PTTs. Polyvalent headsets are also available with or without SIDETONE. Sidetone is a function which allows you to hear yourself through the headset speakers when opening transmission or just when speaking through the microphone.
 
NVolo helmets are very compact in size and weight due to their elaborate construction using several composite fibers: carbon fiber, carbon-kevlar fiber and fiber glass; we apply it in several external finishes by reversing the order of the layers, by color painting or by the Water Transfer Printing process.
 
This specific shell model called CARBON CAMO, has been finished with a Water Transfer Printing process with a desert camouflage theme.
 
We can build your helmet with different headsets models and NVolo accessories, according to the pilot’s needs and preferences.
