How does Sigloo work?

The heart of the Sigloo system is a small radio transmitter, just a few centimeters in size. About 8-10 days before foaling, a veterinarian securely attaches the transmitter to the left vulva lip with two stitches, while a small magnet, flexibly fixed within the transmitter, is attached to the right vulva lip. This procedure causes minimal discomfort, as it’s done with a thread in a needle similar to an injection.

When foaling begins, the vulva lips separate, causing the small magnet to release from the transmitter, activating the built-in radio signal. The signal is then picked up by a receiver device placed near the mare. The receiver alerts those nearby with a beeping sound and, using the SIM  card inside, can call up to four pre-stored phone numbers.

The receiver is equipped with its own battery, making it ideal for use even in remote areas like pastures. To ensure reliable transmission and extended range, a small signal repeater is installed between the transmitter and receiver.

Exceptional reliability and cost-efficiency

Thanks to the design of the Sigloo transmitter, the system ensures nearly 100% reliability with no false alarms. A single receiver can manage multiple transmitters at once, making the system highly economical for breeders with more mares. In contrast to similar foaling sensors (that use vulva-mounted transmitters), which need to be returned for a battery replacement after 5-20 uses (leading to downtime and costs of up to €100),

Sigloo offers a groundbreaking innovation: rechargeable transmitters.

This is a world-first in foaling technology! With a single charge, Sigloo transmitters can handle 5-20 foalings. The battery level can easily be checked on the device, and when it runs low, the transmitter can be fully recharged within 2-4 hours using the dedicated charging station. This means you only purchase the transmitters once, with no ongoing replacement costs. In fact, our first transmitters, manufactured in 2009, are still functioning perfectly today—testament to the lasting quality of Sigloo products.

Sigloo receiver device

Receiver:

In most cases, you will only need one receiver. However, if mares are foaling at two distant locations, you will naturally need two receivers. Each receiver comes with a signal repeater. It is recommended to place the repeater roughly halfway between the mares and the receiver, which significantly increases the reliability of the alerts.

Any number of transmitters can be connected to a receiver at the same time. The range between the receiver and the transmitter is approximately 100 meters indoors (in a stable) and around 1000 meters outdoors. Placing signal repeaters between the transmitter and receiver extends this range. The receiver has a battery that allows for 1-2 days of operation without power. For example, if the horses are in the paddock during the day, the receiver can be placed near the paddock. It is important to protect the receiver from rain with a plastic bag and to shield it from direct sunlight in such cases.

Sigloo transmitter

Transmitter:

You will need as many transmitters as the number of mares expected to foal around the same time. You can start with fewer transmitters, and if you need more, they will arrive within 2-3 days after ordering.

The transmitter is rechargeable. When it is removed from one horse, it can be placed on the next one a few hours later. Charging takes 2-4 hours.

The magnet in the transmitter typically wears out after 3-5 foalings. It is advisable to check the condition of the thread before each attachment, and if it is worn out, a new magnet should be used. After attaching the transmitter to the mare, it is recommended to carefully clean it every 5-6 days to remove accumulated manure, especially around the magnet.

Receiver

Signal repeater:

If the mares are spread over a larger area on the farm, you may need additional signal repeaters to cover the entire area. The best approach is to first purchase the basic system, then, after installation, test the coverage area (making test alarms with the transmitter). Once the testing is done, you can order the necessary additional repeaters to cover any uncovered areas. The signal repeater has its own battery, but it is ideal to keep it continuously connected to a USB plug (or possibly a power bank).

Sigloo transmitter charger

Transmitter charger:

It is advisable to purchase a transmitter charger along with the basic system so that the transmitters can be charged at home anytime. If the receiver device shows that the transmitter’s battery is low, charge it for 4 hours (can be also during a night, this won’t cause any issues).

70 €

Reserve magnet

Reserve magnet:

The magnet is often lost during foaling or wears out after a few foalings. It is always advisable to keep some spare magnets ready.

Stitching set
Stitching set

Stitching set:

We always recommend using the sewing kit we distribute (a thread-needle combination). It consists of Supramid Metric 6 suture thread fixed in an injection needle. This causes the least discomfort for the mare during attachment. Its thickness is ideal, and the thread does not cut into the tissue. The most important thing during attachment is that the stitch should be as deep as possible, encompassing as much tissue as possible, and when knotting, not to pull too tightly. This way, the thread will not cut into the tissue.

Device rental service

If you have only a few foalings per year, it’s more cost-effective for you to rent a device.
The rental fee for the device with one transmitter is €10 per day. The fee for additional transmitters is €2 per piece per day.
Before renting, a deposit of €1200 is required, and after returning the device, the amount exceeding the rental fee will be refunded from this deposit.

Our story

As an equine veterinarian, I used several foaling alarm systems in the 2000s. Each of them had shortcomings: some were not reliable enough and gave false alarms, while others were very expensive to operate long-term.
I shared this with the manufacturer of my ultrasound machine at the time, János Hartl, a medical device development engineer. He was ready to build a completely new system that combined the advantages of other devices without their disadvantages. After two years of intense development and testing, Sigloo was born in 2009.
Since then, more than 1000 stables, renowned breeders, equine clinics, veterinary universities, and equine veterinarians have used Sigloo foaling alarms. The number of foalings we have monitored since then exceeds 15,000.
