I definitely agree that our field techs could do better with regard to ESD precautions and we are going to do some training around that. However, I think it is interesting that A) very little of our equipment ends up being damaged - just the PIC programmers and B) we have never seen an ESD damaged multimeter or scope. These two items lead me to believe that the CCS ICD is particularly ESD susceptible and it would make sense to purchase some programmers which are considerably ESD tougher.
