Johnny's procurement level 3. I only have two digital sensors and I will upgrade Johnny's procurement if I think that maybe he can sell me more otherwise I'm going to use them to upgrade my energy consumption.

The only good thing I ever got from Johnny was a defibrillator and that was very early in the game some people have never even seen a defibrillator this wipe. I have seen two digital sensors. All the level 3 upgrades at the end seem to require digital sensors.
