considering buying Garmin Radar Varia RTL 510 bundle.
There are many reviews and opinions around since first generation of the radar system from Garmin. Without doubt, this is a great addition to safety.
However one aspect that is not covered or discussed is a potential influence on health after long term exposure of cyclist "sitting" on the radar beam.
Spec: Radio frequency/protocol: 24 GHz @ 12 dBm nominal/2.4 GHz @ 4 dBm nominal
I believe no one took this particular radar for any scientific test therefore concerns are more of general nature of being exposed to extra radiation from radar 3-4 hrs a day.
Finally received Garmin Varia RTL510.
On rear side of the box there is Warning from California Prop 65 saying "Cancer and Reproductive Harm". Right way to legally protect itself from Garmin.
In supplied doccumentation there is a following text relevant to this post.
