Abstract: A sprinkler is designed to be stacked upon a like sprinkler. The sprinkler includes a spray tube, a sled, a projection extending from either a top or bottom surface of the sled, and a recess formed at the top or bottom surface of the sled. The recess accommodates the projection extending from the sled of the like sprinkler so that the sprinkler can be stacked with the like sprinkler.

Abstract: A variable range sprinkler apparatus includes a sprinkler portion, a bypass unit housing a plurality of valves, and a water inlet portion. The sprinkler portion of the apparatus, which may be a rotary sprinkler unit, is attached to the bypass unit, and the bypass unit is coupled to the water inlet portion. Inside the bypass unit is a plurality of valves, at least one of which is adjustable, that are designed to open a water passage in the bypass unit.

Abstract: A smart water timer which includes a water timer, a receiving unit connected to the water timer, and a moisture sensing unit which is in wireless communication with the receiving unit. The smart water timer can sense when the moisture level in the soil is too moist (based on a user setting) and turn off a water supply to a sprinkler as a result A soil moisture sensing unit is placed in the soil in the area to be watered. The soil moisture sensing unit uses a moisture sensing probe and wirelessly transmits a data signal to the receiver, which is connected to the water timer, indicating whether or not the water timer should be permitted to open a water valve.

Abstract: A watering device for watering bushes, grass, etc., which has a base unit connected to a substantially vertical riser which is connected to a sprinkler head, wherein the base unit can also have a receiving unit which holds a substantially vertical riser and a plurality stabilizing units, wherein the plurality of stabilizing units are adapted to be inserted in the ground, and wherein the stabilizing units are removable from the receiving unit.
