Instructions
Please read the Operating Guide& the Training Guide and charging the collar before use. A collar worn for too long or made too tight on the pet’s neck may cause skin damage ranging from redness to pressure ulcers; this condition is commonly known as bed sores. Avoid leaving the collar on your pet for more than 12 hours per day. When possible reposition the collar on the pet’s neck every 1 to 2 hours. Check the fit to prevent excessive pressure; follow the instructions in this Operating Guide. Never connect a lead to the electronic collar; it will cause excessive pressure on the contacts. When using a separate collar strap for a lead, don’t put pressure on the electronic collar. Wash your pet’s neck area and the contacts of the collar weekly with a damp cloth. Examine the contact area daily for signs of a rash or a sore.
If a rash or sore is found, discontinue use of the collar until the skin has healed. If the condition persists beyond 48 hours, see your veterinarian. These steps will help keep your pet secure and comfortable. Millions of pets are comfortable while they wear stainless steel contacts. Some pets are sensitive to contact pressure. You may find after some time that your pet is very tolerant of the collar. If so, you may relax some of these precautions. It is important to continue daily checks of the contact area. If redness or sores are found, discontinue use until the skin has fully healed.
Frequently asked questions 1. Q: if I set the center point, will it remember the position each time or does it need to be set every time? A: TThe product is designed with memory function and does not need to be readjusted. It is only necessary to reset the center point when the center point needs to be changed or there is an error in the distance.
Q: Can this system be used for two dogs at the same time? A: No. A receiver collar can only control one dog at the same time. We suggest to purchase two or more if needed for several dogs.
Q: Can the battery be replaced? A: No. The battery cannot be reinstalled. When it shows that the battery is dead, you can continue to use it after recharging. In addition, we provide an extra one-year warranty, so you don't have to worry about it.
Q: Can I set the origin in the house so that it can form a circular fence around the house? A: Dear customer, the GPS wireless dog fence is for outdoor use. We do not recommend you to set the center position inside the house because the GPS device may not find enough signals.
Q: If my dog jumps into the swimming pool with the collar, can it still be used? A: This collar is waterproof, but due to unsafe considerations in the underwater environment, we don't recommend you to let your dog wear it to swim.
Q: How do I know the fence has received the signal? A: The trapezoidal bars in the upper left corner represent the GPS signal strength. The stronger the signal, the more the signal bars.
Q: Why my dog is punished when he doesn't get to the boundary? A: Please check whether the center point is set correctly. If there is a change of position, please reset the center point.
Q: Isn't it suitable for small-sized dogs? A: Yes. This product is suitable for medium-sized dogs and above, please do not wear it on small-sized dogs.
Q: Will the static stimulation scare my dog? A: The product has vibration mode and static stimulation mode, and you can adjust to the vibration mode or adjust the static stimulation level to level 2 for the first time.
Q: What if it doesn't work or the dog crosses the boundary directly? A: After you receive the product, you can set the mode to level 2 vibration, tie your pet to the collar, bring his favorite food, and let him explore the safe pet area: ① Let your pet cross the boundary, hear the warning tone from the product, and then let him return to the safe pet area, and praise and reward him. This is to make your dog associate staying in a pet's safe area with a beneficial experience. ② Repeat this training for 2-8 days: If your dog does not respond, you can strengthen the level, carefully observe your pet's behavior in the boundary area, and see whether your dog will return to the safe area you want after being punished. Repeat the training for 2-3 times with a duration of about 10-15 minutes for each time. Your goal is to keep your dog in the safe pet area all the time.

Hoistspark—Smart Pet Tech
The Hoistspark Wireless Dog Fence stands out with cutting-edge radar positioning technology. It offers the most accurate and reliable boundaries, both indoors and out, when compared to other wireless fences that rely on weaker radio signals.

Real-time distance monitoring lets you stay informed about your pet's whereabouts anytime. The transmitter displays the exact distance to your pet's real-time position, alerting you immediately if they approach the boundary.

I had this unit for almost a year and it was fantastic until it just died. I the receiver just randomly died and now I will buy from another brand because I'm not going to spend that kind of money for something that will only last a year.

I loved how easy it is to set up. I really liked that both the collar and base unit are rechargeable and I would no longer be buying batteries for the collar. The boundary training markers are rather small. I think they may be fine for a small to medium size dog but I have 2 Great Danes, therefore the markers are out of view. The main problem I had was the base unit kept losing connection with the collar. It kept dropping the signal, then the base unit wouldn’t give the proper distance once connection resumed. At one point it said my dog was 45 feet away when he was laying on the deck 15 feet away. I would not feel comfortable relying on the accuracy of this product.
Not for Banana the dog
Banana is notorious for being a little…..difficult. She’s more than a free spirit! I tried to train her with this device, which I had hoped would work well for her,
Banana is notorious for being a little…..difficult. She’s more than a free spirit! I tried to train her with this device, which I had hoped would work well for her, as she’s very smart, but unfortunately my little rotten Banana is a bit too wild. I do, however, believe that with the right dog, and the right trainer (I have little experience training) that this device would be great, so I gave 3 stars despite the fact that it wasn’t a good fit for us.
Play space of differing sizes
Received this product a few days after we decided to try an ‘invisible fence’. It seems to offer a fair distance from its base, and would be ideal for smaller pet
Received this product a few days after we decided to try an ‘invisible fence’. It seems to offer a fair distance from its base, and would be ideal for smaller pet play spaces. We played with the distances and the versatility in that is nice to have. Over all an easy way to train your pet to stay in a specific space.
Really works!
Wow, this fence really works. We have a chow chow who likes to go for a bit of a wander and has no respect for cars. We're still working on his training as chows
Wow, this fence really works. We have a chow chow who likes to go for a bit of a wander and has no respect for cars. We're still working on his training as chows are very independent, but so far it's looking promising. The device works perfectly as described, any failure is going to be our fault. I would definitely recommend this product.
Works very well

This collar has really helped train and keep my dog from getting out and exploring the neighborhood . Setup was easy. The wireless design is so much better than having to install actual barriers. We even took it camping and it was really nice that I can adjust the range to keep our dog closer. The training features are pretty cool and I’m able to adjust it. The collar itself is lightweight and durable and the battery life is really good.
Not great
Doesn’t seem to work well all of the time. It sometimes does well and other times doesn’t work at all. Battery dies quickly. We’ve tried it for a few months now

We just recently moved into our new dream home that had everything other than a fenced in backyard for our little puppy. We kept doing research on this "new electric fence design" versus the standard chain link or wood one and ultimately decided to give the electric one a try. Instructions were clear and we were able to get it completely installed within a couple hours. There are multiple strength/shock settings and a beep. I wasn't brave enough to try it out personally but my husband was, lol. Prices for these range from $100 to $100s of dollars. Some providing things I would never even dream of needing or using. This one we decided on had great reviews and customer service answered all of my questions promptly. This is an excellent product and will be sure to keep our little Bella safe.

This wireless radar dog fence / collar has been absolutely wonderful, I am so happy with my purchase! It’s very easy to set up and no digging/installing wires is involved which is phenomenal. The range is up to 120 feet and it can monitor up to 3 dogs at a time which has been very helpful, especially because I dog-sit for my mom so it’s no great to have that peace of mind! My dog got used to the product quickly and easily, and there aren’t any subscription fees, etc. so it’s a one time purchase without a bunch of strings attached which is rare to find nowaday, I’m highly impressed with this product and would definitely recommend it to others.
