- 해변가 금속탐지기(물깊이가 5 피트를 넘지 않으면 물속에서도 탐지 가능) 

The New Cobra Wader Series is just like its Big Brother the Cobra Beach
Magnet (land/beach/surf/ water) detector with these 2 exceptions;

1) The New Cobra Wader comes with standard lightweight headphone 
    that is splash proof but NOT submersible.
2) Searchcoil and the Control Unit can be submerged.
   Not pressure rated for depths over five feet.


If you do not plan to stick your head into the water (with your non-submersible
phones) to see what your find might be, or to detect in deeper water (6'-130')
the Cobra "Wader" gives you the same detecting depth and sensitivity as the
Cobra Water/Beach/Land Metal detector.

The answer is simple! Save money and choose the New Cobra Wader series.....
