The T20 is an excellent choice because it’s about the same cost as the T10 but has double the tank capacity (20L), and much higher max spray rate of 6L/min (T10 is 2.4L/min).

Whilst the T10 and T30 are more recently released models, the T20 still has many of the same capabilities including a terrain tracking radar, FPV camera, and the ability to make prescription maps (using Terra software) from a Phantom 4 RTK / Multispectral map.

Overall a very good choice if you have the budget for a T10 but want to cover more ground per day of spraying/spreading.
