Collars are the predominant way of radio-tagging mammals, except for mammals whose necks are wider than their head. For large mammals, durability and a range of adjustable sizes are important. Other materials are possible for large collars. Please contact us to discuss your ideas.
Suitable for medium and large mammals. Biothane collars are both flexible and tough, but do not degrade like leather and can not be frayed like braided nylon. Having been developed and used in horse equipment the edges are rounded and so comfortable for most mammals. They are secured with a bolt on the side of the tag, making them highly adjustable. Alternative connections with cable-ties - for a speedy attachment - have been tried, so please ask if you want to try.

* “Light” “Usual” and “Heavy” refer to the potting, i.e., the protective layer around the transmitter and cell. Tags that might get chewed, or are likely to be submerged, need heavy potting, whereas small birds need tags to be potted lightly, because they are unlikely to damage the tag and it is important to keep the weight down.
** All of our radio tags are made to order so the pulse rate (milliseconds) and pulse length (pulses per minute) can be customised for lifespan/detection range. Please see the tag chooser or contact one of our Technical Sales Advisors for more information.
