Designed for emergency situations, this all-in-one communications tool runs on the Inmarsat BGAN network. Ideal for those who travel offshore and may find themselves in distress and outside of cell phone or VHF range, RapidSat provides users with a Wi-Fi connection. It also offers voice and data connectivity to help alert the Coast Guard or nearby ships. The unit charges with an AC adapter, but should you lose power a lithium battery backup gives you 24 hours of uninterrupted transmission time. RapidSat comes standard with a waterproof Pelican case.
