Introducing New and Enhanced Performance Features

Dyna-Link 2 is lighter and more portable than its predecessor. It interfaces with industry-standard Crosby® shackles and a variety of accessories and options, including wireless connectivity with the MSI-8000 and 8000HD RF remote display. Long-range viewing is enhanced by a large six-digit, 1 inch (25.4 mm) LCD display with resolution settings up to 5,000 divisions and precision accuracy over a wide range of capacities.

Dyna-Link 2 is constructed of high-grade, aircraft-quality aluminum with an anodized finish and gasket sealing to ensure NEMA 4/IP65 rated environmental protection. Peak digital processing with low power consumption provides up to 300 hours of operation from standard common batteries during typical use. The optional MSI-8000 RF remote display provides full-function remote control of Dyna-Link 2 features up to distances of 100 feet (30m). An integrated serial port offers interface capabilities with data collection devices.
