Black Sun,
I have a pdf issue of the May 2006 Milieuziektes.nl featuring a comparison of the HF Digimeter II, VL Spion, Esmog Spion, Profi Spion and Profi Spion 2. I am going to try to attach it here. If it doesn't work, let me know if you want me to email it to you. See here:
bitjeE2605n.pdfThe Priggen Website says this about the Esmog Spion Braodband 50Hz-8GHz, but you probably already know this:
