EM31 vs EM38 Post

What is the difference between the EM31 and EM38?

Compare Geonics EM31 and EM38 Both measure apparent conductivity per meter as well as the inphase ratio of secondary to primary magnetic field in parts per thousand. Their measurement resolution is +/-0.1% of full scale, making their ability to discern targets about the same. Their components and operating controls look fairly similar. Essentially, the EM31 and EM38 work on the same principles and …
