Z1 STI Discontinued

The new option designed for the Z1 full face helmet is a special fit for the Skytronic Pro Audible Altimeter and Freefall Computer. The option allows skydivers to fully operate the Skytronic without removing it from the helmet. This gives easy access to all the functions of the instruments, like the extended jump information, programming, altitude check, and so on. The Skytronic is firmly held in place by a small holder on the inside of the Z1, that can be easily removed with the supplied tool when it's necessary to remove the instrument (to replace batteries, for example).
