In DJI Mavic 3M, the M stands for multispectral. This Mavic 3 version couples a RGB camera and a multispectral camera that lets you survey and analyze your field and crops to determine how healthy your crop is as well as any environmental stress that might be present.

The Mavic 3M’s multispectral camera has 4 X 5MP  and its RGB camera has 20 MP 4/3 CMOS, mechanical shutter. The five camera setup lets you capture G (Green), R (Red), RE (Red Edge), and NIR (Near Infrared) bands of light wavelengths. Thus, capturing the visible and nonvisible light wavelengths that are being reflected off the plants and soil.

It has a sunlight-sensor integrated in the top of the drone structure. This is used to record  how bright the sun’s irradiance is as it is reflecting off the different surfaces of the area included in the aerial surveying. This data is very beneficial for improving the NDVI results and comparing data results for subsequent survey flights.

It has Omnidirectional Object Avoidance and can Transmit signals from 15km away. It is also equipped with RTK Positioning so you do not have to use ground control points to achieve precision GPS/GNSS location positioning for the images being captured.

The Mavic 3M’s battery capacity has a cruise time of 43 minutes so it will allow you to achieve surveying up to 200 hectares (494.211 acres) each flight mission.
