DJI Matrice 4TD vs DJI Mavic 3T

The Matrice 4TD is the stronger inspection and public-safety tool: a 48 MP mid-tele and 48 MP tele with 250 m zoom, a laser rangefinder reaching about 1,800 m, an 80° upward-tilting camera for bridge undersides, 12 mm wire detection, IP55 weather sealing and a 54-minute flight time. The Mavic 3T is the lighter, more portable choice at 920 g, folds down small, and still carries a 640×512 thermal camera and omnidirectional sensing, but it lacks the rangefinder, the upward tilt and the higher-resolution thermal output. Owners of both lines praise DJI's thermal imaging and controller ergonomics; the 4TD's extra payload and range are what reviewers point to when the job is critical infrastructure.

• Choose the Matrice 4TD if you inspect bridges, towers, power lines or roofs, need a laser rangefinder, upward tilt or wire detection, or fly in rain and dust.
• Choose the Mavic 3T if you want a compact, foldable thermal drone you can carry in one case for search and rescue, fire scene surveys or quick site checks.
