Product Description:

The Yard Enforcer™ comes factory programmed in Intelligent Sensing Mode. This mode conserves water and batteries by detecting significant, repetitive activity (false alerts) and then reducing the activation frequency to 1 per minute for 1 hour. During initial setup, you may reach this limit while adjusting the sprinkler’s position. To disable Intelligent Sensing Mode: turn dial to OFF position, then press and hold 30 MIN Watering button for 20 seconds until unit clicks. To re-enable Intelligent Sensing Mode: repeat steps above

Preguntas frecuentes

Some questions and answers are automatically generated.

How long do these sensors typically last?

Most reviewers report good longevity with some units running for years, but durability varies significantly. Several customers note that sensors fail after 1–2 seasons of use, with some reporting that a percentage of units purchased over time have required replacement. One long-term user has relied on Enforcers for over 15 years with replaceable parts available.

Does the sensor detect motion at a distance?

Motion detection range appears inconsistent. Some customers report the sensor requires motion to be quite close to activate reliably, with one reviewer noting disappointment that sensitivity was poor and the detector needed things to be "way too close." Others report successful detection of deer, squirrels, raccoons, and geese at usable distances, though adjustment and positioning affect performance.

Can the sensor be adjusted for smaller animals?

Yes, the product description notes it includes a small animal bracket for adapting the sensor to a lower position for smaller critters, allowing positioning flexibility to detect a wider range of target sizes.

Does it activate on wind or false triggers?

At least one customer reports the sensor is sometimes activated by strong winds, suggesting it can be sensitive to movement other than animal motion. Setup and positioning may influence false triggers.

What happens if the sensor activates during day mode at night?

One reviewer reported the unit activated unexpectedly during daytime hours when set to night mode, indicating a potential issue with the day/night function on some units, though this appears to be an isolated experience among the reviews.

Are replacement parts easy to install?

Reviewers describe installation of replacement sensors as quick and simple, with one customer noting it took only a minute to swap in a replacement sensor and restore full function.

What pests does it effectively deter?

Reviewers confirm success deterring deer, squirrels, raccoons, cats, and geese using water spray activation from the Enforcer. Some users report needing adjustments for optimal effectiveness on specific animals, and results can vary by setup.

Is customer support responsive if there's a problem?

Multiple reviewers consistently praise customer service responsiveness, noting quick replies and willingness to troubleshoot or provide replacements. Several customers highlight prompt resolution of defective sensor issues through chat, email, and phone support.

It doesn’t work with the older models sprayer system

Keeps the deer from destroying my garden.

We have a lot of deer that travel through our property. I have been using these sprinklers since 2020. Without them, deer eat all of my garden plants. Recently, I noticed a feral tomcat spraying my firewood pile. I tarped the wood and pointed the Enforcer at the wood pile. I have not seen (or smelled) the tomcat since.
I appreciate the thirty minute timed watering also.

Works fine!

Works fine, but I prefer the older style with no hose connections. A choice would be nice.

Bad valves

They sent the sprinkler over night which was awesome. After I put it together and turned it on it would not turn off. Talked with customer support, they sent me a new valve. Put it together spent another hour on the phone with customer support sent them several photos and videos. Another faulty valve. They are going to send me another. Hopefully it will work

My motion sensor didn’t detect motion after I pulled it out of winter storage

My motion sensor didn’t detect motion after I pulled it out of winter storage. I when to the website and chatted with a rep who asked several questions and then provided me with a credit to replace the defective part of the unit. I have since received it and the Enforcer works perfectly once again.

The one star isn’t for the motion sensor per se

The one star isn’t for the motion sensor per se. But the orbit enforcer sprinkler head has leaked and we have replaced parts and it continues to leak. For the money we spent on this, additional motion sensor, additional sprinkler head, plumbers-tape, and everything else we can think of doing including a pressure gauge, it it still leaks like a sieve. It now is as useful as a garden gnome.

Thank you for letting us know about your experience with a leaking Sprinkler Head. Our Customer Care team is happy to discuss your product concerns and to provide further assistance for any issues that are still being encountered.

I have used Enforcers for 15+ years to keep deer out of vegetable garden

I have used Enforcers for 15+ years to keep deer out of vegetable garden. The day/night I shut it off in the Fall the deer clean out anything left in the garden. The deer population has grown, eating everything, tulips to hemlocks. I now protect everything with Enforcers. Winter is still a problem.

It barley sees me when I walk in front of it

It barley sees me when I walk in front of it. It will not turn on unless I'm no further than 10 feet away. I don't see how it could possibly detect the birds I'm trying keep away from my pool and fence.

Thank you for leaving your review about our Yard Enforcer Sprinklers not detecting movement in close range. We're glad to know how our Customer Care team was able to assist with your warranty replacement for the sensors, and ask that you reach back out to us with any other concerns that you may have or if further help may be needed in the future.

Works as advertised !

I bought the Yard Enforcer to protect my fish from the local raccoons.
The first night on duty, it had them critters wet and rattled and headed over the fence. They might come back, but now we’re ready.
Great product.
Thanks 🙏🏻

The motion sensor becomes usable after a couple seasons

The motion sensor becomes usable after a couple seasons. Lens clouds and should have better UV Coating

Great

Its great!!! Im just have a hard time on how thesensor works but all in all works as needed.!! MAKE SURE TO USE THE TAPE it will help stop small leaks

Average performance

Sometimes it works and sometimes it does not. I have seen a cat pass by thru my motion camera. At one time it worked but it took a while before it reacted to the cat within its field of vision. Another incident, the cat passed by and no response at all from the Yard Enforcer (the range is set to max).

Thank you for your review about our Yard Enforcer Sprinkler not detecting motion consistently. In addition to checking the range adjustment on the device, please also make sure that the angle of the sensor on the mounting arm isn't too steep, and that Intelligent Sensing mode is not turned on (this feature increases the delay between activations). For further assistance, our Customer Care team would be happy to help and can be reached by phone at (800)488-6156 or online at support.orbitonline.com. Have a great rest of your day.

Replacement Valves

The problem that caused me to call about the 2 valves persisted. As a result, I measured the pressure of the water into the manifold and coming out into the valves. The pressure into the manifold was 40psi and the pressure coming out of the manifold was 10psi. That's the reason the sprinklers are not popping up. You sent me a replacement manifold 2 days ago and I'll install it as soon as I received it. I'll return the existing manifold to you if you like. I REALLY APPRECIATE ALL YOUR COOPERATION IN RESOLVING THE PROBLEM! If I can act as a reference supporting Orbit, I'd like to.

It worked

I bought this to prevent a squirrel from eating my strawberry flowers. Turns out - you are supposed to clip the flowers within the first year of planting so they develop deeper roots.

Welcome wildlife, and repel them sustainably : this sprinkler did everything as advertised and it's awesome.

Works about half the time

Works about half the time. You can hear it click to come on but nothing happens and then come on at times when nothing triggers the enforcer.

Thanks for leaving a review on the Watering Valve for your sprinkler working half of the time. Please do make sure to replace the device's batteries with new ones if you have not already, and check that the valve plugs are inserted correctly.

Previous ones sprayed water all the time - even when turned off or unplugged

Previous ones sprayed water all the time - even when turned off or unplugged. This one doesn't spray water at all. Yard enforcer is still non operational after trying four new parts.

After receiving A replacement for the faulty sprinkler head it works perfectly

After receiving
A replacement for the faulty sprinkler head it works perfectly. So far, it is stopped any damage to my perennials and is the only area in my yard that hasn’t received damage from deer and rabbits. I am very happy with your product.

Sometimes works

Activates randomly sometimes, doesn't activate with deer other times. I'd put accuracy at like 70%
