Hi there,
I am looking for a coordinate logging device with the following capabilities that is cheap to buy in bulk (looking to buy about 50 for the first batch, under $40 a piece):
- Battery must last at least 1 week
- Offline coordinate logging is sufficient, no need to track in real-time
- Logging coordinates every 5 to 10 minutes is sufficient
- Some port (for example, USB) to upload the coordinate data of an entire week
- GPS and/or cellular triangularization suffices, no WiFi capabilities needed
Any recommendations? All the loggers I find are either way too expensive with too many real-time features, or require continuous power supply.
Thank you! Much appreciated!
