Australia also has the highest per capita emissions in the OECD, with 26 tonnes of greenhouse gasses being emitted per person every year.
Australia's C02 emissions rise for the 4th year in a row.

Reading the thread re the best mid size coils for the QED, just which size coils fall into each size categories (small, medium, large) seems to be an interesting topic.

For example, is the 15” round evo a mid size coil or is it at the bottom end of the large size category.

Obviously Reg’s huge coil is a large coil, or it it an extra large coil.

I would be interested in which coils our fellow prospectors feel fit into each category.

Me too Goldman on how each prospector / detector operator would categorize coil sizes.

Therefore if I was to look at my Commander coil arsenal, 8" & 11" monos , 11DD, then I would call them small.

Now do I call in my Nuggetfinder coil arsenal, 12 Adv. & 12" Evo monos small or medium along with my 24" x 12" Adv. mono.

Also again in my Nuggetfinder arsenal, two 18" monos & 25" Adv. mono, then I would call them large.

Also in regards to Eliptical coils, for example in lengths of 14", 17" & 24" then to categorize these do you use the length + width divided by 2 or do you go by the width only.

I reckon the above is a good size to category split . 777s view is very similar as well
 Thanks everyone

I have looked and asked but it would appear that the manufacturer hasn't posted any comparison videos.

The video of a new 11" coil fitted to the SDC2300.
The SENSITIVITY was set at the maximum of 5.
  

Compare with the QED fitted with an 11" Coiltek Elite coil.

 Thanks for the video bugwhiskers.
This video shows why
Coiltek didn't give much away in regards to test results.
I think people who had the sdc just wanted a variety of coils for it.
So now they have a choice.

The video was done using my phone. Will do again with higher resolution.

The small targets in containers on the surface are (in order) 0.033g  0.08g  &  0.24g

The new 11" SDC coil does not appear to me to provide any measurable  depth increase  and  seems to result in a drop of sensitivity for  some  of the some smaller bits!!The QED with the same coil to me beats it for sensitivity and eats it for depth on the bigger bits.

Other than for more ground coverage why would anyone with an SDC buy the 11" coil?

Here is the link to the previous SDC2300 video with it's standard 8" coil.

The small targets are 0.033g  0.08g & 0.24g

The targets really pop out with the QED and the 11” elite, especially the very small gold nuggets and with some air distance. Interestingly, the QED got all targets (albeit the 3rd buried target) with the 11” elite and the SDC only got one buried target (just) and had trouble getting the smallest gold nugget with the new 11” coil.

The results are in for all to see, and in this prize fight there is clearly only one winner  - the QED.

Our fellow prospectors, consumers are the real winners. They just have to get over the last quarter century of brainwashing.

I have removed the low resolution video and replaced it with a much better quality video shot early this morning.
