DJI Matrice 4TD vs DJI Matrice 4T

Both are DJI Matrice 4 enterprise drones with the same 640×512 thermal sensor, 48MP tele cameras and 1,800 m laser rangefinder, so image tools are close. The 4TD is the tougher, longer-flying airframe: IP55, -30°C to 50°C operation, 54 min flight time, 25 km O4+ link and an 80° upward-tilting camera for bridge and structure undersides. The 4T is lighter at 1,219 g, folds smaller, and is the easier aircraft to carry and hand-launch, but it is rated only -10°C to 40°C and has no IP rating. Buy the 4TD for rain, cold, dust and upward inspection work; buy the 4T for compact everyday inspection and search where weight and portability matter more than weather sealing.

• Choose the Matrice 4TD if you fly in rain, dust or sub-zero cold, need the upward-tilting camera for bridge and high-rise undersides, or want the longest flight time and the O4+ link.
• Choose the Matrice 4T if you want a lighter, more compact three-camera thermal drone for routine inspection and search work in mild weather.
