The submersible VX-820 series of wide band portables offer an incredible range of features in a small package (only 4 inches tall, 2 inches wide!). The VX-820 Series of portable two-way radios are specifically designed to perform in the most demanding and critical conditions with extreme IP55 and IP57 spec water and dust protection

The VX-820 series waterproof portables can actually be submerged under 3 feet (approx. 1 meter) of water for 30 minutes and come up in perfect working order, ready for action.

This is the perfect portable radio if you're a dedicated Public Safety officer or a tough environment commercial user - rain, snow, fire suppression spray and dust are no problem. Manufactured to strict ISO 9002 and MIL-STD specifications, the waterproof VX-820 series will perform when you need it most. With industry leading features such as Lithium Ion battery technology and advanced programmable user defined features, the VX-820 series waterproof submersible portable 2-way radios have set the new standard for Public Safety and commercial applications now, and in the future.
