Does it work on a motorcycle?

Yes. On a motorcycle it is especially practical: the small dongle and antenna are easy to tuck away, and your phone is usually already in a mount.

Carshepherd is a tool for situational awareness and road safety, so that you can make way for emergency services in good time. It does not read or decrypt any communication. Use it responsibly and follow the traffic rules.

Comparison

A cheaper, affordable alternative to the Target Blu Eye

Q: Is Carshepherd the same as the Target Blu Eye?

No. The goal is comparable, being warned in time about approaching emergency services via the C2000/TETRA network, but Carshepherd is an app with an inexpensive SDR receiver instead of a built-in device.

Q: What is the price difference?

A Target Blu Eye quickly costs 1,000 to 1,500 euro plus installation. With Carshepherd you pay around 50 euro for hardware and 3.99 euro per month, with the first month free.

Q: Does Carshepherd detect the same signals?

Yes. Both respond to the C2000/TETRA transmissions of emergency vehicles (the uplink) and show proximity. Neither reads nor decrypts any messages.

The Target Blu Eye is an excellent, ready-to-use system — but with a price that quickly reaches €1,000–1,500 plus professional installation. Carshepherd offers the same core idea (being warned in time about approaching emergency services via the C2000/TETRA network) as an app on your phone with a cheap SDR receiver — from around €50 in hardware. Below is an honest comparison, so you can decide for yourself.

Target Blu Eye is better if you…

…want a ready-to-use solution without any tinkering, want it neatly and professionally tucked away, and price is no object (no phone or subscription needed).

Carshepherd is better if you…

…want to spend far less, also ride a motorcycle, don't want professional installation, want flexibility (multiple vehicles or devices) and want new features on an ongoing basis.
