Out of Stock - Summary: Great Value But Limitations
The EF-4000 is the base model in the Dogtra lineup. It has a particularly impressive feature set for it’s price, with independent correction & boundary zones, a small collar, and 8 correction levels.
But, there are limitations. The system can only contain 2.5 acres (1,500 feet) area and the collar has no low battery alert.
Adjustable Boundary Warning & Correction
Dogtek gives you control over both the boundary warning distance, and the boundary correction distance. You can independently set these boundary distances which lets you tailor setting to your dog’s temperament and your yard’s configuration.
Dogtek also lets you set the correction levels on each collar independently, allowing you to accommodate dogs of very different sizes and temperaments. The range of correction lets you
Small & Light Collar
The EF-4000 has one of the smaller and lighter collars for regular sized dogs. Despite the small size it has eight correction levels. But, it lacks a basic low battery indicator.
8 Correction Levels
The EF-4000 has eight correction levels ranging from very-low to medium-high. The correction levels give enough range to suit most dog, although very large or very stubborn dogs will need a high powered collar such as the PetSafe Stubborn
The correction levels are changed by pressing a tiny button in the battery compartment. The button placement is inconvenient, and the size of the button is so small it requires you to use a pen to press. However, you will likely only use the correction level adjustment a few times when you are first training your dogs and will thereafter leave the correction level unchanged.
No Low Battery Warning
The EF-4000 lacks any low battery warning on the collar. This means the battery can die on the collar and because it has no status light or other indicator, you will have no idea that the battery has gone flat. The only solution is to either change the battery early (say every three months), or test the collar with the supplied tester tool regularly as it approaches the end of it's life. Either way it is an inconvenience, and we are surprised the collar lacks this basic function.
Long and Short Prongs
The system comes with both long and short collar prong attachments, so can be used out of the box with both long and short hair dogs. Providing both types of prongs on this entry level system is a generous extra usually only seen on the higher priced systems.
Disposable CR2 Battery
The collar is powered by a disposable CR2 battery, requiring you to keep buying new batteries to keep the collar in working order. But, the battery is a non-proprietary battery that is available at most big-box drug-stores and is moderately priced at around $5, which makes it a lot more economical than the proprietary batteries used in the Petsafe, Perimeter Technologies, and Invisible Fence dog fence systems.
Changing the battery is a minor chore, requiring four screws to be undone. However, with a battery life of around 4 months, changing the battery is a relatively infrequent occurrence.
Lightweight & Small
The EF-4000 collar is one of the lighter and smaller full-powered collars. The collar will comfortably fit any dogs over 12lbs. For dogs, under 12 lbs a dedicated small dog system with a micro-collar such as the PetSafe Little Dog
system is necessary.
The collar fastens using our preferred cloth strap with a quick-snap buckle. Additionally, the strap slides around the outside of the collar so can be easily removed for washing or replacement.
Transmitter with Adjustable Boundary
The new Dogtek EF-4000 transmitter allows you to adjust both the boundary correction distance and the boundary warning distance. This allows you to have a completely custom boundary that suits the needs of your dog and your layout.
Adjustable Boundary Warning & Correction
The Dogtek EF-4000 (and it’s big brother the EF-6000
) let you adjust both the boundary warning distance and the boundary correction distance. This gives you a lot more control in your boundary set up and allows you to find a setup that will suit your dog.
You can for example set a wide boundary tone to trigger 10 feet from the boundary wire, while having the static shock correction start only 3 feet from the wire, giving a timid dog plenty of warning zone buffer. Conversely, for a more hard-headed dog you could have a small warning zone preceding the correction zone.
2.5 Acre Capacity
The EF-4000 transmitter can only power 1,500 feet (2.5 acres) of boundary, making it one of the weakest containment system.
For a higher capacity system, consider the Dogtek EF-6000
(up to 5 acres), the Petsafe Ultrasmart
(up to 25 acres), and then SportDog SDF-100A
(up to 100 acres).
Boundary Wire & Accessories
The basic system includes 500 feet of 20 gauge boundary wire, 50 training flags, and 3 wire splices. It also includes a collar tester.
Direct Burial Rated Wire
The Dogtek Wire is direct burial rated, and is PET coated. PET coated wire is more resilient when buried than the more common PVC coated wire that rots out in the ground and degrades with exposure to sunlight.
500 Feet of 20 Gauge Wire
The EF-4000 system includes 500 feet of 20 gauge boundary wire. It also includes 50 boundary flags for marking the fence boundary while the dog is in the training phase. The wire and flags are enough to cover one-third of an acre. Extra boundary kits can be added to expand the system up to 2.5 acres.
||Wire Required (feet)
Optional Professional Gauge Wire
Basic 20 gauge wire can be upgraded to thicker 18, 16, and 14 gauge wires. 14 gauge wire is considered professional grade and is what is typically used on a professional Invisible Fence installation. With the 14 gauge gauges of wire, both the wire and protective jacket are four times thicker than standard wire. This makes the wire stronger, more durable and less to break.
For small installations, upgrading the wire is an easy low cost way to massively reduce your risk of wire breaks. A small 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 and because of the reduced probability of developing a wire break, but the cost of upgrading large amounts of wire are significant.
One Year Warranty
The Dogtek EF-4000 come with a full one year warranty, covering both parts and labor. We find Dogtek systems to be well made, and rarely needing service. But where needed, warranty claims are adequately and promptly addressed.
Dogtek’s EF-4000 is a curious blend of high-end features and glaring omission. The system outperforms systems double the price in some respects, with complete control over both the boundary and correction distances. The system collar is lightweight and has eight correction levels.
But, the system also has some significant limitations. The range of the system is a pitiful 2.5 acres so should only be used with suburban lots. And the collar has not low battery indicator so needs to be checked at least weekly.
If you can live with these limitations, this system is a steal at $150.
