The Invisible Fence Company is the original producer of electronic dog fences and has a full service offering where they provide the system, install the system, and help you with training. Invisible Fence was the only game in town for a long time and have done more than a million installations in the United States. But, since the expiry of their patent in the 1990s they are now joined by a variety of do-it-yourself solutions. Invisible Fence is in fact a sister company to Innotek and PetSafe which make the major DIY electric dog fences.

The Invisible Fence ICT 700 series which includes the ICT 700, ICT 725, ICT 750, and the ICT 775 has been the Invisible Fence workhorse for as long as we can remember - well over ten years and probably closer to twenty. The four models in the 700 series are similar. * Invisible Fence ICT 700 - basic model that can run 3,000 feet of wire (about 10 acres) * Invisible Fence ICT 725 - adds a rechargeable battery backup * Invisible Fence ICT 750 - has dual zones, so you can run two independent section of boundary wire off a single transmitter * Invisible Fence ICT 775 - long distance model that can do about 5,000 feet (25 acres)

All the Invisible Fence ICT 700 is being phased out, and is being replace by the Invisible Fence ICT 800 series. The new 800 series systems are little faster to respond, but it is almost academic because the old 700 series worked just fine. You can also use the new Invisible Fence UltraLite collars with the ICT 700 series.

The 700 series is usually paired with the platinum collar which is equally well. It is waterproof, has a nice cloth collar band. The collar does have two serious drawbacks. First, it uses a special Invisible Fence disposable battery that you need to get under a subscription plan ($60 for a year). And second, it is not user adjustable. The collar has ten correction setting - but they can only be adjusted by an invisible fence technician. So if you get a second hand unit or use it on a new dog with a different temperament, you need to get someone to adjust it for you.

An Invisible Fence ICT 725 will cost you around $1,500 depending on where you live and the size of your yard. Each extra dog costs an additional $300 for the extra collar. For that price someone will come out to your house and install the system. There will also be two training session to help show you how to train the dogs. The system itself is covered by a lifetime warranty.

SUMMARY: An excellent system supported by excellent customer service. This is a great option if money is not an issue. The only downside is the price of the system and the need for the ongoing battery subscription.


The Invisible Fence ICT 700 can be used with a few different Invisible Fence collars. The newest microlite collar is reviewed here along with the newer ICT 800 Invisible Fence. Most ICT 700, ICT 725, ICT 750 and ICT 775s are sold with the Invisible Fence Titanium (R21) collar. It is one of the smaller collars, comparable in size to the better DIY systems like the Innotek IUC-4100 and PetSafe Deluxe. The size is fine on a dog down to about 11 lbs.

The collar probes screw on to secure the cloth band. A cool feature is that there is a large selection of bands available, so you can get different ones for each dog to identify the collar. The band uses a nice buckle style clasp for quick removal.

The collar has ten different correction levels and also lets you set a delay on the correction to give the dog time to retreat before getting the correction.

On one side of the collar there is an indicator lamp that lets you know when you are getting a low battery. On the other side of the collar is a disposable Invisible Fence Battery. The battery is available through Invisible Fence and costs approximately $60 per year. There are cheaper compatible batteries available in our store for about half the cost, but they are still expensive.


The transmitter has just one control. The two blue dials control the boundary width.

The wire terminals on the transmitter are a bit bigger than normal and can accommodate thicker wire, up to about 12 gauge. Most of the DIY systems by comparison can only do about 16 gauge, without needing to be trimmed down.

The transmitter can be plugged into an optional extra battery backup that is included in the ICT 725, ICT 750, and ICT 775 models. The battery is rechargeable and charges when using the main AC power source. This battery backup supplies power to the system in case of power failure.

The system has a status light and a speaker to let you know if there is a break in the wire.


You can use the Invisible Fence System with both indoor pods and the outdoor rock pod to keep the dogs out of certain areas of the house and yard respectively. The units look identical to the pods that work with the Innotek/PetSafe IUC-4100 and IUC-5100, but are not intercompatible.


The Invisible Fence Brand systems come with a lifetime warranty on the system, which means that they will repair the system at their cost if there is a problem.

Other than if, what kit/product do you advise that is at least as good as if. A client had if (hit by lightning) I do not like proprietary products. One 60lb dog, 2 acres, wired, 1 collar (rechgable), backup battery if possible… Anything I missed? Thanks Kurt

ADMIN – Hi Kurt. I would recommend taking a look at our Dog Fence Reviews page as it has all of the systems we currently sell along with their features. None of the systems we sell offer a battery backup. However, you can counter this by buying a universal power source, like you would use for your computer, at any office supply store. I would recommend taking a look at the PetSafe YardMax system and the PetSafe Inground PIG00-13661 as two systems that may work well for you and your dog.

Maureen July 1, 2017 at 10:44 am

I have a new rescue dog and am training her on my existing ICT700 model LP3000. Does this model zap if the dog tries to get back in after a bolt?

ADMIN – Hi Maureen. That is a system that is put out by Invisible Fence. You would want to contact them for specifics on how their system operates.

We have a backyard we are trying to close off however we have a privacy fence in the back of our property. We want the electric fence to close the sides off but the fence is sufficient for the back portion of the property. I was thinking a double loop but do not want to cut off an extra 6 feet away from the fence. I do not think I can do the double wrapped wire that long as it is 2/3 of the distance I will be laying. Can I just space them right next to each other for this without the 6 foot spacing and then just increase to the 6 foot spacing where I need it? Thanks.

ADMIN – Hi Josh. because you are running a double loop layout for your yard, you CAN use the twisted wire in the middle to create a gate or a dead zone in your loop. However, you will want to twist the wire in that section as the signal will not be reliably cancelled unless you do actually twist the wires. As it MAY be too much length to twist your boundary wire, you can purchase pre-twisted wire and splice that into your double loop. That would be the best way to accomplish what you are talking about for your fence.

I recently moved to a new home and took my invisible fence transmitter with me from from my old home. I want to keep my dog from digging along a fence but I cannot have loop enclosing the perimeter because in order for the dog to get into the yard she would have to step over the loop to get into the yard. If I bury a wire loop in a narrow trench running the length of the fence and attach to the transmtter will it act as a boundary from the fence or will the fact that the two wires that form the loop are sitting right next to one another cancel out any field effect? HELP! 🙂

ADMIN – Hi Warren.
What you are describing sounds like a double loop layout, also referred to as a single-sided layout. In this layout, you would need to keep at least 6 feet between the wires going out and coming back. Please visit our Planning/Layouts page to see a diagram of this and other layouts.

I recently rented a house that has invisible fence. The previous tenants installed it and took the transmitter with them when they moved out. I have 1 large dog and 1 medium dog both take off after squirrels so I need a strong correction. The property is half acre but I am not sure how many feet of wire there is in the ground. How do I know which transmitter to buy? 725 801 802 or 810? I don’t know the difference between the 800 series transmitter other than what you posted about the 800 series being faster to respond. Can you assist in clarifying the difference between them.


ADMIN – Hi Susan. We do not sell the transmitters for the Invisible Fence systems. However, provided that the wire that is currently in place is still in good shape and is no thicker than a 14 gauge wire, you can use any of the transmitters we sell with the wire that is already there. Please visit our Dog Fence Review page to see what systems we offer.

Eric Walls January 3, 2017 at 11:03 pm

Why does the collar beeps inside the loop. When I lay my loop it beeps inside the loop but stops beeping when the collar is outside loop?

ADMIN – Hi Eric. From what you are describing, it sounds as if your wires may be in the transmitter backwards. Try flipping your wires in the terminals and test your loop again. When the wires are backwards, this causes the extended correction to be on the INSIDE of the loop instead of the outside.

Tim Garner October 2, 2016 at 9:03 am

Hello, we have a ICT 725 system and the electronic collar has been broken. Our neighbor has a ICT 700 collar they are offering to sell. Will it work and what other issues might we encounter? Thank you. Tim

ADMIN – Hi Tim. As they are both 700 series, the collar should work with your system. However, as it is an Invisible Fence brand system, we do not have the particulars on each system and collar.

Lesa Anderson September 25, 2016 at 12:44 pm

We have an IF Boundary Plus System.We recently got a new puppy. Are there any other collars other than the 397.00 one I was quoted by IF that will work with this? If not, can i have a microlite collar programmed by IF to work with the boundary plus?
Thanks, LA

ADMIN – Hi Lesa. That system is exclusive to the Invisible Fence brand and, as far as we are aware, does not offer an off brand compatible collar.

John May 28, 2016 at 2:07 pm

We have an Invisible Fence ICT801 with three dogs. We have a second house and the neighbor has an older ICT725 model that they are willing to give to us. I couldn’t get our collars to work with the 725 system (either on 7k or on 10k). Are the systems incompatible, or is there a problem with their transmitter? Everything seems to be ok on their system (no beeps, I even disconnected the wires and did a 10 foot test loop).

ADMIN – Hi John. The 700 series and 800 series do not have compatible collars.

Keith April 1, 2015 at 7:12 pm

I have the ICT 700 and tried to expand our perimeter to about 3000 feet and we have checked and re-checked the wire and still it shows a break in the line. Is it possible the unit is not strong enough for my length of wire?

ADMIN – Hi Keith. I’m sorry to hear about your wire problems. I would recommend using 14 gauge boundary wire at the DogFenceDIY store.

Lisa Pratt December 7, 2014 at 11:13 am

Our plug was pulled out of the outlet and the wires pulled out of the plug. I have 1 wire that needs to be connected from the ICT 700 to the plug and 2 wires coming down from the wall that need to be connected to the outlet as well. The top of the plug has 2 reds with loop and 2 blacks with transmitter. The same is on the side of the plug. We have 3 wires and 2 are attached together. The other wire is coming from the ICT 700. Combinations I have tried do not work. Would greatly appreciate someone letting me know where the wires need to go. Thank you.

ADMIN – Hi Lisa. I’m sorry to hear about your dog fence system. Please contact Invisible Fence at 1-800-538-DOGS. Please have your sales receipt information ready to give to the customer care representative.

ANGELO FANELLI September 3, 2014 at 4:52 pm


ADMIN – Hi Angelo, unfortunately I think you will need to have your wall transmitter repaired or purchase another to replace it. If you decide to shop for a new one, I would recommend searching on Craigslist and Ebay.

Dale May 1, 2014 at 5:01 pm

I have an Invisible Fence 725. Tx shows slow green blinking light as always telling me the wire is good. Rx is not working. Is there a way to test Rx with a meter?. Do the prongs need to be installed to test Rx? Can I test the Rx at the transmitter box? Replaced batteries & was wondering if the meter will tell me the Rx is operating normal in a static state. Where can I get an economical Rx replacement? (Platinum R21 V2.2 95-445126. Thanks, Dale

ADMIN – Hi Dale, Your problem may not be a collar problem. It may be a problem with the transmitter’s signal. First run a test loop which will help diagnose where the problem may lay. We do sale the R21 replacement for the IF underground dog fence. It is located in our collars page inside our store. You can access it by clicking on store on the menu bar of our homepage.

Marta April 26, 2014 at 2:59 pm

My mother has the ICT 725 series fence. I moved in and have a dog myself and looking for a cost effective solution to obtain a collar for her. A friend of ours gave us a collar to use. It is the same P/N but doesn’t seem to work with our fence. I have replaced the battery. When the battery is placed in the collar the light blinks 5 times, same as the working collars do. Any suggestions or recommendations or am I stuck calling the company and paying $139 for a service call?

ADMIN – Hi Marta, if you are confident that the collar is a 700 series collar, calling the IF installer is probably best. He can calibrate the collar to work with the installed wall transmitter.

dina murphy January 15, 2014 at 4:19 pm

I purchased a boundaries plus invisible fence system in 2012. How do I find the model number?

ADMIN – Hi Dina, you should be able to unsnap the face of the wall transmitter and find on the inside of the cover.

Joy December 11, 2013 at 10:25 am

How does one get the local Invisible Fence Company to respond. I have emailed twice and called once without a reply?

ADMIN – Hi Joy, try calling the corporate number and report the local installer.

Al July 20, 2013 at 10:02 pm

I own a ict 805 series system. My daughter bought a has and it has a ict 725 transmitter. Will my dogs collar work with the ict 725 system. Also, does her system come with a warranty even if she is the second owner.

Kelley December 16, 2012 at 10:32 pm

I’m looking into buying a used invisible fence system. Is this a good or bad idea? It seems like a good way to save money.

ADMIN – Hi Kelley,

You are better off with a system that is intended for self-installation than a used invisible fence system. The invisible fence systems are good and even a used 5-year old system system still has a lot of life in it. But, the systems are intended to be programmed by the Invisible Fence installers and don’t allow the home user to change even basic settings. For example, you can’t adjust the collar correction strength without a special reprogramming device. You are better off with a system that is intended for self-installation where all the controls are on the actual device and the home user can set up the system themselves.

Nick November 13, 2012 at 8:34 pm

We have owned an Invisible fence ICT 700 system for 12 years. For the past two years, the fence was not in use. Now even when using a fresh battery in either of two R21 collars, the system will only “beep” close to the ICT 700 unit, not the boundary wire.
The local IF dealer is telling us the collars may be damaged and may need upgraded @ $200 each. If they were simply stored for 2 years, how ironic would it be that they are BOTH damaged??? (BTW, I only need one to work; they already shipped and charged us for a new $20 battery)
Could the collars have a sleep, or power down mode that simply needs to have the intensity levels reset? (by IF of course)

Admin- Hi Nick,

The collars do not have a sleep or power down mode. The collars could be damage if the old batteries where left inside the collar and they corroded; otherwise, the problems you are having sound like there is an issues with the boundary wire. A bad splice or a splice not making a great connection could cause similar issues. We see very similar results in brand new installs when one of the new splices is not making a great connection. So you should check the new splices again. You could have “nick” in the wire. Since the wire might be “nicked” and not completely broke, the wire still could have a small connection which will confuse the transmitter to think the wire is still making a complete loop and that is why you have a little signal. A partial break is harder to find and the best option will be to run a jumper wire from the transmitter (or splice to splice) to each splice point to isolate each section of boundary wire. This could be time consuming but you will be able to find which area the small break is in.

Doug Wright March 21, 2012 at 7:47 pm

My Invisible Fence ICT 750 keeps beeping. What does this mean and how can I stop the beeping?

ADMIN – Hi Doug,

It sounds like you might have a break in the boundary wire. The first thing you want to do is to run a test loop. Simply unplug your boundary wires from the transmitter and plug in a 10-foot section of boundary wire. If the transmitter stop beeping and the collar works with the transmitter, you will need to purchase a PetSafe Wire Break Locator. The PetSafe Locator will create an audible tone in your boundary wire that you can detected with a AM radio(which is included in the kit included) to help you find the location of the break.

Curtis March 21, 2012 at 7:13 pm

I have a 725 series Invisible Fence transmitter with 4 R21 platinum receiver collars. Is there a outdoor rock transmitter compatible with my system?

ADMIN – Hi Curtis,

Invisible Fence does offer an outdoor rock for containment. We are not familiar with their model compatibility, but if you contact your local Invisible Fence franchise they will be able to help you out.

p schmdit November 11, 2011 at 7:59 pm

how do I adjust the correction setting on an ultri-lite collar (700 series)

ADMIN – Hi Pat,

You cannot adjust the correction. Only your local Invisible Fence Installer can adjust it.

Chris Mattern July 25, 2011 at 10:21 pm


I currently have an ICT-700 system. We can’t find our collar and need to replace it asap. We called our invisible fence technician and he reports our cost would be close to $300 dollars. This seems outragous. Is there any other cheaper non-name brand or aftermarket production collars that I could get by with? Any help???

Admin- Hi Chris,

We do offer a compatible collar for the Invisible Fence 700 series for $149.95. Please see the link below.

Kevin Reese March 2, 2011 at 7:23 pm

How do I remove the delay on my ICT 700 b/c my dog has learned to run through so she does not get corrected?

ADMIN – Hi Kevin,

For the invisible fence systems, you will have to get your local dealer in to adjust the delay. There is a special tool they will use with the collar.
