Hello David, the collar is a transmitter which sends out a continuous radio signal which is picked up by a handheld receiver, if within distance. There are 3 levels of search - long range, medium range and really close up, for finding a lost collar six inches away unseen in deep grass. You wave your receiver around in the air and it becomes evident in which direction the signal is coming from by the loudness of the bleeping. You follow the loudest bleeping. When you’ve done it once then it’s easy.
I found a collar on the edge of some woods where my cat just escaped a fox which dislodged the collar! Crushed buckle. Found another time in a neighbour’s garden under a wheelbarrow again caused by a fox. My cat had recognizable teeth marks on his head both times! Lucky escape. Another cat was gone but I traced him to a local wood and found him deep inside, much to his annoyance! The only problem with woods is climbing over fallen trees or through thick bramble and so on.
It works best on level ground as radio signals can’t go down into a hollow or get the other side of a hill, but it can see through woods and into and through buildings. When a bleep is not evident - the terrain is uneven or the collar is too far away - I get in the car with the receiver on until I get a signal. When it bleeps I get out and walk.
It is expensive to buy and on top of that there may be import duties - but in my case, because I can’t sleep at night worrying - I’m a worrier - it was worth paying for. Both the collar and the receiver are really well made, durable and reliable! And work well.
One thing to beware of is to make sure you change the collar batteries every 4 weeks. If a collar is lost and its battery is exhausted you’ve lost the collar! I’ve lost many collars!
Batteries for both collar transmitter and handheld receiver you can buy in any supermarket in Europe. Best get the collar batteries, Panasonic CR2032, from Amazon in quantity.
I believe the company is a family business but I think the costs are too high. I’ve searched for European equivalents but don’t think there are any. If you decide to give it a try you have to order their European version - something to do with radio waves.
The receiver can be set for up to 30 different collars. Dial in cat no1 or dog no 10 and off you go! You could share one receiver with friends or neighbours and dial in whichever multiple cat or dog is missing.
A young couple living near me who have cats, bought some collars and share my receiver. It can be done.
