The iSolv Crane Master ultrasonic system is designed for use with container cranes. It has four programmable relay outputs to operate anywhere within the programmed span of up to 80m (260ft), and can be set to either energised or de-energised for close proximity and collision avoidance. It utilizes specially designed transducers that are unaffected by either strong wind or rain.

The iSolv Crane Master series have been deployed in ports of Singapore, Asian region and the Middle East in distance monitoring for port cranes.
