Audible altimeter bracket kit for Sport Hat & Retractable Visor helmets by Gath.
This bracket and cover for audible altimeters fits over right ear only. For Gath Sport Hat and Retractable Visor models.
Originally made for Pro-Track and Pro-Dytter. It will also fit the Solo/SoloII and Optima/OptimaII with the Protektor installed. Other audibles such as Brilliant Pebble fit as well, but benefit from a small piece of spacer foam to prevent movement.
