NF 14 X 7/9 vs 11inch commander coil Empty NF 14 X 7/9 vs 11inch commander coil

I have the original coil 11" commander coil standard with the 5000, It has served me well finding .2 gram - 5.2 gram nuggets. I have read other post on here but haven't found any other comparisons against 11" commander and 14X7 or 14X7 nugget finder.
Will the NF increase finds due to sensitivity.
cheers Tim

Hi Tim,

I didn't realise the 5000 came out with a 9 inch round. Mine came with two 11inch rounds a mono and DD.cI have a 12x7 Nf and find it great to use. It's very quiet. 

 Cheers

Might be talking about a 8"mono round???

comparisons against 11" commander and 14X7 or 14X7 nugget finder
I believe you mean 12x7 & 14x7 NF.
The NF coils should find you smaller gold because they'll scream the signal out louder than the 11", but that's not to say the 11" wont pick it up. What I'm saying is that both will pick it up, but the signal on the NF coils should be more distinct. The 11" though, should give you more depth in the more open areas.

Gee I'm having a lot of luck on here, I wanted to compare the 11" commander to a 14x7 NFA and or 14x9 NFA
hope this clears my confusion up
Cheers Tim

It's always a bit of a debate as to how to work out the equivalent depth comparison between a round and an elliptical. Some say you ad the length and width and then halve them, but my rule of thumb is go with the narrowest part (ie the width) and the equivalent round will be just a smidgen bigger. For example a 14x9 will be eqivallent to a 9"round and a tad bit more, possible 10", with more ground coverage and better pinpointing ability and a more sharper response on the smaller ones at the sacrafice of a very little bit of depth (the 11" round is extremely well tuned to the detector, hence it's great performance).

Thanks CostasDee
You answered my next question on how you compare sizes between Round and elliptical.
I would like to purchase another coil. I'm happy to take the sub grammars as they come. Would I be better to buy a larger coil for better depth maybe 16" or 18" and stick with the 11" mono
thanks Tim
