Integration flexibility
A neck-mount platform designed around system integration.
Ranger is designed for neck-mounted installation and can support application-specific valve-thread and interface requirements.
Standard adapter options use M18x1.5 valve threads, with 5/8-inch threads available as an option. Custom valve threads up to M25 / 1 inch can be accommodated upon request.
Other mounting strategies may also be considered where the system design requires a different integration approach.
