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. Please contact us to discuss your ideas.
Degradable, so good for conservation species.
Comfort: Less flexible
Durability: Moderate, degradable
Fastening: Bolt plate
Antenna: Usually external whip
Popular for Badgers and some Monkey species

* “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.
