The BlueFly models are designed for slightly different purposes. Which model you should get depends on:
- What device you plan to connect it to; an android phone or tablet (with or without an internal GPS), an iPhone, a Windows PC, a Kobo, or perhaps you just plan to use the Bluefly as a standalone device.
- How you plan to connect it; Bluetooth, USB-OTG, USB for desktop, or TTL-Serial.
- What app you plan to run on the device; just the BlueFlyVario app for adjusting settings, xcsoar, XCTrack, FlySkyHy, LK8000, or other apps.
