It would be interesting to see the temperature difference between the bottom of your hole and topside on a 40 degree day.

That's a good idea. I'll measure it on the next hot day.

Are you going to measure the difference in temp at the bottom of your hole., indoors and outside. :)

[@SubterraneanRalph]

@@BackyardBunkerBuilder I'll need another thermometer for that. I was going to use a digital one...

[@BackyardBunkerBuilder]

Loved the update mate. How deep are you now?

[@SubterraneanRalph]

I forget.. I think it was about 2100 I'll measure it for you.
