Thumper Specification Review
Don’t handicap your fault finding efforts by buying a thumper with only half the features necessary, like some with no hipot output. For the same or less money you can buy a full featured thumper. Always specify: vt33

• A variable hipot output with high burn current of at least 200mA
• At least two full joule output voltage settings, preferably three,
and with at least 1000 joules of energy for URD, 3000 for Network
• Variable discharge rate from 6 – 10 seconds
• A remote TDR/radar, not one built-in, for flexibility,
versatility, ease in service, and ease in use
