FAQ / Common Questions
Q: Can the DROP connect to the ballistic Kestrel app?
A: No, the DROP does not connect to the Ballistics app. It connects via Kestrel LiNK for environmental data. [oai_citation:35‡Kestrel Ballistics](https://kestrelballistics.com/kestrel-drop-d3-pressure-temperature-humidity-logger)
Q: How do I prevent battery drain when idle?
A: Set the logging interval to the maximum (12 hours) and data refresh to slower rates to conserve battery. [oai_citation:36‡Kestrel Ballistics](https://kestrelballistics.com/kestrel-drop-d3-pressure-temperature-humidity-logger)
Q: What happens when memory is full?
A: If “Wrap Log” is enabled, the oldest data is overwritten; otherwise logging stops until data is cleared. [oai_citation:37‡Kestrel Ballistics](https://kestrelballistics.com/kestrel-drop-d3-pressure-temperature-humidity-logger)
Q: How far can the Bluetooth connection reach?
A: Around 100 ft / 30 m line-of-sight. Environmental factors may reduce range. [oai_citation:38‡Kestrel Ballistics](https://kestrelballistics.com/kestrel-drop-d3-pressure-temperature-humidity-logger)
Q: What use cases is DROP D3 good for?
A: Ideal for shooting ranges, weather stations, industrial monitoring, agriculture, and indoor/outdoor facility conditions. [oai_citation:39‡Kestrel Ballistics](https://kestrelballistics.com/kestrel-drop-d3-pressure-temperature-humidity-logger)
