The BD502i has been in the US market since 2017, and it has been by far our most popular DMR radio the last few years. This radio is a business series device from Hytera and has an IP54 rating against water and dust intrusion. You can program 48 channels and 3 zones into the BD502i (digital or analog). A 1500mAh Li-Ion battery is also included with the BD502i for up to 16 hours of operation in digital mode.
