Above is our A1 spring and trigger combo. This combo was created by the need for a lighter trigger release and a simpler way to set the trigger. This trigger can only be set in one position which makes the release more consistent versus other models on the market today. The spring itself is of a high quality stainless steel and returns to its 90 degree shape when released giving you the full force of the spring and maximum cable pull. All of the Lights Out Snaring models will be identified by a stamp on the trigger . A1 is stamped on the back of the trigger and is a simple way to check you have our product. The A1 model was designed for animals from fox to wolverine.
