idk about that, a heltec is 15-20$ while t-echo is 55-65$.

no problem :)

Hope you liked the information.

I also tried it when I was skiing in the winter. It was cool. I have GPS on my nodes. and I can tell where my friend is, tried also the telemetry sensor to tell the ALT but since it only tells the pressure it is not intuitive. You can probably tell if the person is up or down

Hmm, yeah. Well for me I am not an expert guy. I am looking to get license free comm device, I see Meshtastic with text comms and PMR with voice.

Perfect I got also GIzont they are pretty good, Enjoy meshing
