Heat Seeker Heat Detector
Heat Seeker Heat Detector is a self-adhesive oestrus detector that improves cattle heat detection. It uses Channel and Chamber technology for strong adhesion and clear, progressive colour change, so you can time AI with confidence.
What is Heat Seeker?
A tailhead indicator that shows mounting activity and helps identify true standing heat quickly.
Why choose Heat Seeker Heat Detector?
- Channel and Chamber design reduces false positives and is easy to read.
- Moulds over the backbone, large surface area, one-person application.
- Self-adhesive strength suits dairy and beef herds in all seasons.
Packs and colours
- Pack sizes: 20 and 100.
- Colours: three bright options for easy mob management.
How it works
The detector requires sustained mounting pressure before full activation. Colour then progresses through the chambers, indicating the level of activity.
Application tips
- Apply to clean, dry hair on the spine, usually just behind the hips.
- Remove loose hair, avoid tail paint or recent pour-on areas.
- Do not reposition once placed. In wet weather, dry the area as much as possible.
