METAL PROBE - underwater pinpointer (1)

Since 2002 I have exported pinpointers to Euro and USA and with time pass I found many brands and models appear online and too much fakes . so I plan to design the world smallest underwater pinpointer and it is impossible or very difficult to copy.

To distinguish with other pinointers I call it  metal porbe and set up a website www.metalprobe.com in 2011

Metal Probe has been developed for 5 years and during the developing I have got feedback and suggestions from the dealers and metal detector works

I know when products can be copied, all my and dealers effort will be zero result.

metal probe is electron item but people first impression is shell, so no matter how excellent the PCB board was made，unique shell is first key to consider.

finally I decided to design short and small tip dia. less than 0.55 inch and it is one body the thickness is from 3mm to 8mm which is impossible quantity produced by Mould so the process cost is much higher than normal pinpointer.

I will list all differential advantage step by step ( to be continued )
