HPRC RMX2730W-01 Overview This watertight Hard Case for the DJI Ronin-MX from HPRC features wheels and a retractable handle designed to make travel easy. Based on the HPRC-2730W series, this case comes with a pre-cut foam interior that holds the DJI Ronin-MX gimbal, the transmitter, four spare batteries, two battery chargers, tuning stand, camera mounting plate, handle bar, cables, and other miscellaneous accessories.The case is impact- and drop-resistant, corrosion-resistant, and features a neoprene seal that when properly closed can keep the case watertight and your gear protected, even if submerged in shallow water. A release valve allows you to equalize air pressure when traveling between different elevations.The modular nature of the interior means that after you've stopped using the DJI Ronin-MX you can repurpose this case by replacing the foam cutout with either the HPRCCUB2730W foam or the HPRCSFD2730W divider kit.
