The adapter with an ID number “420xxx” is used to connect a steel wire and slowly lower it down the hole. There is no switcher on the probe so you don’t need to disassemble GDY-2GW during the whole measuring process. Once being assembled with the battery housing, the GDY-2GW will automatically start to work. The probe is powered by a 7.4V rechargeable lithium battery, which can be charged no less than 500 times. The endurance of the survey tool is about 20 hours.
