The PetSafe Ultrasmart PIG00-13619 (formerly Innotek IUC-4100) has enjoyed nearly a decade as our top-dog fence. But, it is starting to show it’s age and has been surpassed by the new PetSafe YardMax which does more at a lower price. It is still an excellent and reliable system at a good price.
We still love the fundamentals on this system. Build quality is great, the collars are slimline, and the batteries rechargeable. The system also includes nice-to-have features such as battery backup, indoor/outdoor zone compatibility, collar-fit testing mode, and progressive correction.
No Independent Correction
Out of the box, the system doesn’t support independent correction levels for different dogs on the same system.
PetSafe have started including the lightning protection module free with the basic system. This is one of the few systems where this is not a $40 an optional extra.
The killer feature of the PetSafe Ultrasmart is the collar. The system is built around a slimline rechargeable collar. It performs the magic act of being one of the smallest collars, but still being powerful and full of features.
Slimline and Lightweight Collar
The PetSafe Ultrasmart collar is the thinnest full-sized containment collar. While the collar is small, PetSafe stretched the collar to achieve the slimline finish. This makes the collar less visually obtrusive on your dog. While many collars can appear like a big box hanging under your dog’s neck, the PetSafe PIG00-13619 has a much smaller visual footprint.
The collar is also lighter, allowing it to be used with dogs as small as 12 lbs. For dogs smaller than 12 lbs, a dedicated small-dog system such as the PetSafe Little Dog Fence is more appropriate.
Rechargeable Lithium Ion Battery
The Ultrasmart collar is fully rechargeable. To charge, simply place the collar in the included charging cradle. The collar light remains red while charging, then change to green when it is fully charged. A full charge takes 2 hours and lasts about 4 weeks.
The battery and collar have shown excellent longevity and are proven to last. Owners of the previous iteration of this collar, (the Innotek IUC-4100) report collars and batteries continuing to perform after 6 or more years of use. That said, the collar battery is not user replaceable so if the battery does fail you will need to send the whole collar back to PetSafe for replacement (around $35).
Long and Short Contact Prongs
The standard system includes both long and short contacts (prongs) in the box. The collar prongs can be unscrewed with the included tool and replaced with the long prongs for long hair dogs, or the regular prongs for short hair dogs.
No External Controls
There are no controls on the collar itself. Instead, the controls are located on the transmitter box. Having the collar free of buttons and knobs makes it smaller and more durable because controls on a collar are more likely to break or malfunction.
The system includes a pair of yellow no-correction caps that can be placed over the prongs to prevent a correction being felt by the dog. This is useful in the first week of training where you want to be able to teach the dog the boundary without issuing a correction.
Plastic Collar Band
The collar has an integrated integrated design. It is made of high quality plastic, and some of our team considers it modern and sleek, but most of us would prefer a cloth band. The collar is waterproof and wears really well. Our oldest collars appear new with the exceptions of a few scrapes. The collar closes using both a traditional buckle and quick release buckle for adjustments and fitting.
Three Progressive Correction Levels
The correction level for the collar is set at the transmitter. The collars have three progressive correction levels: Low, Medium and High. The correction starts at the level you set, but then increases the longer the dog lingers in the correction zone and the closer the dog gets to the boundary wire.
The correction range on this collar is suitable of almost all dogs, but may not be quite strong enough for the most hard-headed breeds. Dogs that are particularly insensitive to the correction such as fighting and guardian dog breeds may need something stronger. (e.g., Pitbulls, Dobermans) These dogs would likely benefit from a stronger system such as the PetSafe Stubborn.
No Independent Correction Levels
While the lack of controls on the collar is a positive feature for durability, it also means that you cannot set the correction level for each dog independently. (There is a workaround, the resistor hack.) Every dog must to be on the same starting correction level. Thus if you have two dogs that are very different in size (> 30%) or temperament, then the PetSafe Ultrasmart is not the best choice. Instead consider a system with independent correction such as the Dogtek EF-6000 or the SportDog SDF-100A.
The warning beep on the collar is not loud enough for the human trainer to hear. To make the collar durable and waterproof, PetSafe sealed the speaker inside the collar. While this is great for waterproofing, this leads to a muffled warning beep that is hard to hear for adults (children and dogs seem to be able to hear just fine!). This means that during the training phase you need to either have keen ears, or rely on the collar indicator light and/or the dog’s body language to know if the collar has been triggered.
Collar Fit Test
The PetSafe Ultrasmart collar helps you get the collar fitted properly. Improperly fitted collars are the second most common reason (after lack of training) an in-ground dog fence doesn’t get 100% containment. Improperly fitted means the probes do not make contact wit the dog’s skin. When this happens the dog does not consistently get the correction and learns that the boundaries can be ignored. This issue is particularly relevant to long-hair dogs where fitting the collar can be tricky.
The Ultrasmart has a ReadyTest mode where the collar makes a clicking sound when it is properly fitted. This eliminates guessing and lets you get a perfectly fitted collar every time.
The transmitter (aka. base station) connects to the boundary wire and creates the radio signal that is picked up by the collars. The transmitter is the brains of the dog fence system. The Ultrasmart transmitter has all the regular features, plus a few extras.
25 Acre Capacity
The transmitter can create a boundary of up to 25 acres (around 5,000 feet of boundary wire). This makes it one of the highest capacity systems. If you need an even higher capacity, the SportDog SDF-100A can contain a 100 acre property.
Includes Lighting Protection Module
The Ultrasmart includes a lightning protection module standard with the kit. You run the boundary wire into the lightning protection before running it into the transmitter. This module protects the transmitter in case the boundary wire gets struck by lightning. This is particularly useful for large installations in areas where lightning strikes are common. Having the lightning protection included standard is a nice extra that is seen in few other systems and saves you $39.95.
The boundary zone, the distance between the boundary wire and the point where the collar starts beeping, can be adjusted using a dial on the transmitter. You can set the boundary width anywhere from a few inches to 10+ yards wide.
The correction zone, the distance from the boundary wire that the collar starts correcting the dog, is always set at 80% of the boundary zone. Unlike the Dogtek systems, the boundary zone cannot be independently set.
The transmitter has a battery backup so it will keep working even if there is a power outage. Insert 8 AA batteries in the back of the unit and if there is a power failure, you get 2-3 days of power before the batteries are drained.
Battery backup is a useful feature in places where power outages are common. But, for most urban dwellers with reliable power, this is not terribly useful. If power failures are only occasional, your dogs will not realize that the fence is off.
Direct Burial Rated Wire
The wire is direct burial rated, meaning that it will hold up better in the ground than standard electrical wire. The boundary wire is surrounded by a PET jacket. This protects the wire against the elements better than standard PVC coated electrical wire that will tend to rot, particularly in acidic soils.
Professional Gauge Wire Available
The standard 20 gauge wire can be upgraded to 18, 16, and 14 gauge wire. 14 gauge wire is considered professional grade and is what you would see on an Invisible Fence installation. With professional grade, the copper wire and protective insulation are both four times thicker and stronger than the standard wire. This makes the wire stronger and more durable and therefore less likely to break.
For small installations, upgrading the wire is a no-brainer. A modest additional cost reduces the likelihood of you needing to hunt for wire breaks.
For very large installations, the thicker gauges of wire are useful because of their superior transmission characteristics. However, the additional cost becomes significant.
Standard 500 Feet of 20 Gauge Wire
The Ultrasmart basic kit includes 500 feet of standard 20 gauge wire, 2 wire splices, and 50 marking flags. This is sufficient to cover 1/3 of an acre. Extra wire, wire splices, and marking flags can be purchased in our store. The 20 gauge wire kits cost $30 and include an extra 500 feet of wire, 2 splices, and 50 marking flags.
Wire Required (feet)
The system includes a blue tester tool that lets you check if the transmitter and collar are working. Hold the tester tool against the collar probes and when the collar is activated by crossing the boundary line, a light on the tester tool will glow.
The PetSafe Ultrasmart is compatible with wireless indoor and outdoor zones. These wireless battery powered pods can be used to create small circular exclusion zones from 2 to 12 feet in diameter to keep the dog out of small areas. For example, drop one of the indoor pods in a room to stop the dog going into the room, or slip it under a sofa cushion to keep the dog off your couch. Or use the outdoor pods to keep the dogs out of flower beds or a fish pond.
The system also has a limited lifetime warranty – that is a clever way of saying it has a one year warranty. After the year there is a fixed charge for repairs. The repair charge depends on what part breaks (around $30 – $50). Build quality on these units is excellent so hopefully you will never need it.
The PetSafe Ultrasmart enjoyed a run of nearly ten years as our go-to system. It is still a good reliable fence that does all the basics well. In addition you have some useful features such as the slimline rechargeable collar, the collar-fit test, and the compatibility with indoor & outdoor pods.
The Ultrasmart does have a few deficiencies, most notably not being able to adjust the correction level for each dog independently. But, if you don’t need the extra features, the PetSafe is an excellent choice.
But, it’s biggest deficiency is that there is a newer system on the block the PetSafe YardMax.
