Hi there.
I'm searching more about meshtastic and I'm really into this concept, it seems very cool to have something like this.

And I also have a question that would like to see if someone can get it answered for me.

I know you can see meshtastic nodes on a map, but I'm thinking to use it with a team of search and rescue, therefore... how fast are the updates, and what do we need to be able to see our locations in remote places? I think it kinda works offline, but not sure how that would be working.
Does anykind of meshtastic device allows it, does it need to have WiFi?

I was thinking something like this, because they look kinda inexpensive.

Many thanks for you time and help.
