I'll try and add a few more targets in the coming days / weeks, as well as re-testing all of the above on the stock coil.

Note: Due to various factors, air testing is not considered an accurate benchmarking method. The above results are for curiosity purposes only.

Cheers,

As you can see above, the .13gram gold nugget gave a slightly better reading than the .2gram nugget. I put this down to the fact that the .13 is a solid little piece where as the .2 is a little more flattened out.

You'll also notice that for most targets I added two measurements (i.e. 30-33cm), the first being a definite "dig me" signal while the second is where the signal is almost completely faded out but still showing slight signs of a target underneath the coil.

Hey nugget, if you still have the test set up could you do a 50c on end?
Also your 1grammer 90 to however you were holding it?

Thanks

I haven't got it all set up at the moment but I'll do that next time and report the results. Everything tested in my first post was held parallel to the coil.
