This PRO-POD system is an alternative sound option for helmets from the regular Helmet Kit or Ear Plugs.
The Rugged Radios PRO-POD is a padded gel ear cup with Alpha Audio Speakers that can be used with any 3.5mm mono input jack for sound in your helmet. If you have struggled to hear your pit crew with your previous system then these will certainly improve communications, considerably increasing noise reduction.
The Pro-Pod is very popular with Impact helmets but may not fit all other helmets without a certain level of modification.
