How do I know my collars are ready to go?
Collars should still be stored according to our collar storage guide until you are ready to collar.
When one LED light on the collar flashes green, the collar is healthy and talking to the Halter tower(s). You are ready for collaring.
Collar Fit Instructions
When collaring and checking the fit, make sure the animal's head is in a neutral position (not too high, low, or turned).
Place the collar on the narrowest part of the neck, just behind the jaw.
• If fitted while the head is down, the collar will tighten when the head returns
to neutral.
• If fitted while the head is up or turned, the collar will loosen when the head
returns to neutral.Ensure the buckles on both sides of the strap are within two holes of each other to keep the collar balanced.
You should be able to comfortably fit three fingers horizontally between the strap and the side of the animal's neck.
If the collar can be pulled over the animal's head, it's too loose.
Tuck any excess strap into the rubber sleeve.
After the animal walks away, visually check the fit again. The counterweight should sit snug against the neck with no visible gap.
Collaring your animals
1. Attach weights
Before you start collaring, you need to attach the weights to one side of the collar. If this is completed before collaring day, the collars can hang via the weights, so both panels are facing the sun.
Feed one strap through the camlock. Close the camlock buckle through the holes that are the correct size for your animals. Work on average sizes to speed up the day.
Don’t attach the weight to both sides of the collar.
Test collar sizing and fit by collaring a few animals
before attaching all the weights to the collars.
2. Tag collars on in the app
Use the Halter app to assign the collar to the animal’s ear tag number.
To do this, open the Halter app, select ‘More’, select Collars, and then ‘+’.
Continue to follow the instructions on the screen.
The LED will light up green on the side of the collar where you will need to scan.
3. Place the collar next to the animal
Place the collar on the rail next to the assigned animal or directly on the
animal’s neck. Ensure the correct collar always goes onto the correct animal.
The collar can be placed on the animal in any orientation, but the LED will light up green on the side of the collar where you need to scan the NFC to tag the collar.
4. Loop the collar around the animal's neck
The person fitting the collar picks up the tagged collar.
Hold both ends of the strap and sleeve, and loop it around the animal’s
head without letting go.
Or lay the collar on an animal's neck
Gently drop the weight-end on the far side of the animal's neck and lay the collar on the top of her neck. Reach underneath the animal’s neck and grab the weight.
5. Fasten the camlock pins
Push camlock pins through the same numbered holes as the opposite side
of the collar to ensure the weight is hanging centrally on the animal’s neck.
6. Check collar size and fit
When the animal’s head is neutral, not flexed or bent down, bring the
collar to the narrowest part of the neck. The lowest part of the weight
should touch the bottom of the neck and not hang loose. If the collar does
not fit, adjust the sizing on both sides of the collar, ensuring the weight is
still central.
7. Feed the strap into the sleeve
Feed the strap through the rubber sleeve.
