Netafim MegaNet Sprinkler, Blue Nozzle, 24° Head
Seeded vegetable ground needs water that settles the soil without washing the seed out of its furrow. This rotating impact head, Netafim item 63600-002000 and model MGN24D-198HO, is built for that work. The blue cap marks a nominal flow of 1.98 GPM at 33 psi, from a 2.79 mm nozzle. Water leaves through two identical jets on either side of a turning rotor, so the head spins evenly without wobble. Drops stay small and gentle near the ground, which keeps the soil from grooving at start-up and shutdown. That steady pattern helps germination, because seed stays covered for the whole run. An integral filter at the inlet keeps grit out of the nozzle and lifts out for cleaning. A pop-up cover opens only while water is flowing, so insects, spiders and dirt stay out between cycles. The body is made from UV-protected materials that resist fertilizers and agrochemicals. It threads onto a riser through a 1/2 in male connection.
Laying Out a 24 Degree Trajectory Block With the Blue Nozzle
The high angle throws the stream farther, which suits open beds, nursery blocks and frost protection runs. Run the head between 29 and 44 psi, measured at the sprinkler rather than at the pump. At 36 psi the blue nozzle delivers about 2.03 GPM, rising to about 2.22 GPM at 44 psi. On a 33 x 33 ft grid that works out to roughly 0.18 to 0.20 in of water per hour. The same nozzle still covers a grid as wide as 33 x 39 ft at a lighter rate. Its stream peaks about 5.3 ft above the nozzle, roughly 18 ft out from the head. Keep that height in mind under shade cloth or low wires. Filter dirty surface water to 40 mesh, and put a hydrocyclone ahead of the main filter where well water carries sand. Rinse the inlet filter before each season and never run the head without it. The black locking pin under the cap marks the 24° model and holds the rotor in place, so keep it seated after servicing.
