Of those of you who have had experience what is the better nozzle in your opinion
I grow a wide mixture of veg, potatoes and cereals so just looking for the best all round nozzle really

There's no one size that fits all. 3Ds are great but prone to drift though they are better than the older versions. GATs will be less prone to drift but you'll need higher water volumes and bigger nozzles or you'll get a lot of blockages especially with trace elements and suspensions. The GATs are 2 nozzles in one, so if you have 03 Defys at 100 l/ha and 2 bar you'll need to have at least 05 (2 x 025) and run 160 l/ha at 2 bar.

For blight spraying or higher volumes in bigger veg you'd be better off with a Potato nozzle for less of an angle and better canopy penetration.

I run 025 Bubblejets at 100 l/ha and 3 bar in angled caps and alternating backwards/forwards along the boom but that's for cereals & oilseed rape.

The GA twins are 2x nozzles each of half the overall output. Therefore an 02 is like 2x 01's. This means they block much easier because of the smaller orifices.

Is it best to go for the largest nozzle then 08 or would they still block easy?

What's the coverage like on a potato nozzle? May be worth getting these? As we grow 30ha Spuds and a fair few cauli and Sprouts so need some coverage and penetration

I run 05 Lechler IDKT ceramic twins for 200 l/ha applications, very happy with coverage and few blocking issues. Expensive but will last a long time.
