Electronic pocket scale for gold

Hi, I am looking for a very precise scale to weight gold nuggets, possibly 300gr/0.01, any particular brand do I have to look for, I have three already from China but they are good for nothing, any help will be appreciated.

You cannot go wrong with the "TANITA" (Japan made) series pocket digital scales. Especially the model 1479j  0.01 x 200g or 1579 mini scale.
Tanita does have a slightly more expensive 300g scale (1479S) but the increment rise is from  0.1g not 0.01g  (0.1 x 300g)  Anything more accurate than this in the 300g scale & above, is just to expensive for our average daily nugget finds.  The  6.43oz scale above (1479j) has more than enough accuracy & just about covers 99% of our gold finds.  

Cheers Kon.

Thank you Kon61, is all I need to know, Cheers and Happy New Year.
