If you're flying in dense terrain or just want some added peace of mind, pick up these Propeller Guards for Mavic 4 Pro from DJI and enjoy a safer flight. This full set of guards are designed to install and disassemble quickly. When in place, they cover the drone's propellers with their frame but do not hinder flight performance and add only 6.6 oz of additional weight. By extending past the spinning blades, they are the first thing to come into contact with people and property in the event of an accident, greatly minimizing the chances of injury or damage.
