Yes, Raj, I think it is though I haven't heard that from him.
Regarding the PLJ-6LD counter, there is an interesting video on YouTube examining and demo-ing the unit. Google it.
I have found a web page with the manual too, in English. You can download it but it is the Chinese version. Only the web page has
the English version (in PDF).
Hope this helps.
