| 説明 | Battery life is about 21 days. Transmitters will be replaced every 18-20 days. The transmitters are attached to the frog with a cotton thread inserted inside fine, soft surgical tubing to prevent skin abrasion. The cotton thread lasts approximately 25-30 days before it decays and snaps, ensuring an auto-release mechanism for any frogs the cannot be recaptured should the transmitter fail prior to scheduled replacement or removal. |
