More Details

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

Frequently asked questions

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.

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. We can be reached by phone at (800)488-6156 or online at support.orbitonline.com for help. Have a great rest of your day.

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.

Didn't work

I received the unit and it wouldn't detect any movement except at 90 degrees. Orbit sent me a new sensor head and it was aimed better but it did not detect the birds that I was trying to deter... The unit has been packed up with both head in the same package and is being returned through Amazon... I'm now looking for something different for bird deterrant.

Thank you for sharing your review and experience with our Enforcer Sensor not detecting the birds you were trying the deter.

A Less Expensive Alternative

My Yard Enforcer unit became inoperable, and I attributed it to motion sensor problems. The purchase of a new motion sensor immediately remedied the situation, and allowed me to get my Yard Enforcer back into action without purchasing an entirely new unit

Very disappointed in the motion detector

Very disappointed in the motion detector sensitivity it doesn't pick things up until it's way too close I've tried several different angles and nothing works

Thank you for leaving your review about the sensor for your Yard Enforcer Sprinkler not picking up things until they're close. Please do check that the range adjustment on the sensor isn't set too low and increase it as needed, and replace the batteries with new ones if this has not been done already.

A clever design, easily repaired.

Range is not as great as my first unit. Also, the elevation adjustment is less flexible than my original unit: you have to lift the entire housing to elevate the sensor.
Otherwise, it still does the job and keeps the deer out of my planter. I rely on this unit's effectiveness, and I appreciate that I can replace different parts of the unit without having to throw out the whole thing when a part wears out. This is a clever, consumer-friendly design that I've used for 8 - 10 years.

Orbit products fill huge gaps of things we all need

Orbit products fill huge gaps of things we all need, that no one else seems to have -WITH QUALITY PRODUCTS. Their yard enforcer is awesome, and reliable. Its electric eye detects and sprays loud water at deer and squirrels away from my fruit trees, strawberries, and other vegies.

4 of 10 Enforcers not so great

I've purchased 10 Enforcers over the years, 4 of the 10 have quit working.
The enforcer works great but its durability not so great. I've yet to install the 2 I just purchased, I'm sure they'll work fine hopefully the longevity has improved.

Please make sure that the range adjustment is not set too low, and that the angle of the sensor on the mounting arm isn't too steep and adjust this if needed along with having the batteries replaced.

Watering cycles don’t work

Bought 2 more to add to the two I already have. The two new ones won’t work on the 30 minute watering cycle. My other older 2 work fine. Think they had a bad batch They do activate with motion so I’ll keep them.

Thanks for sharing your review about the watering cycles not working on our Yard Enforcer Sprinklers. We do stand behind our products and are glad to know how our Customer Care team was able to help with the product issue that was being encountered. Please do reach back out to us with any questions and concerns that you may have, or if there's further help that may be needed in the future. Have a great rest of your day.

I’ve had 2 of them for a few years. They are good for hungry animals trying to eat plants. If you have a trail camera it’s even better watching them run for the hills.

As long as they work they do a good job of discouraging the deer. However I have 3 that have gone bad in something like 3 years. And I am not aware of any way of repairing.

Sensors

I have had 6-7 Yard Enforcers over the years. They work about one or two seasons. However they need to be replaced after 1-2 seasons. I believe the sensors become defective. It could be other problems as well. I do like the product; but wish it lasted longer
