When in the field and one of those cheap 'disposable' instruments fail and pointed questions are asked That's when you miss the quality of the old HP gear And I still use the old pre Carly gear precisely because it can be trusted to work in adverse conditions even though one needs to wash the data through a computer to get the measurement features that the new stuff has built in
The new gear had a name at one time we called it experimenter grade. Much of the new gear these days reminds me of Eico equipment in overall build quality Content by Scott Typos by Siri > On Feb 14, 2016, at 2:20 PM, William H.
