They don't get much use these days either,except out at the property.
Mobiles phones are the go,unlimited calls and TXT's.
And the boys even have these bluetooth electronic gauges with temp probes and clamps,so from the cold room,they know all the system pressures and temps,superheats,even if the unit is way up on the roof.Using their phones.
 
I haven't got a set,just use the old Imperial Eastman gauges,they do me.
 
oh,and feel the pipes for temps,a bit of spit on the discharge to see how hot it is...
