Motion Activated Sprinkler is almost useless against Heron

After a couple of days, heron will get used to the sprinkler and can hunt right in front of the sprinkler. Also, this Scarecrow model as well as other brands all use standard sprinkler heads and does not allow the spray to be adjusted lower than about 25 degrees. So as you can see this this video, the bird is only getting a slight sprinkle at the water level. Once he get used to the noise of the sprinkler coming on, it is no deterrent at all. Video shows the Scarecrow model I mounted onto a wood base so I can move it around my deck. The yellow sticker has faded out after a year.
