Recently many questions have been asked about the new HF coil from XP. One that regularly crops up in conversation is “How do the higher frequencies compare to the black coil running at 18kHz?” Taking everything into consideration, and to be perfectly honest, the answer is – I really don’t know.
The more you look into the theories the more you realise it depends on so many variables. There are many technical reasons why one coil could be, or is better than another, but when real time detecting in the field, you quickly realise it can throw up many other challenges compared to a simple bench test. I guess logically the first question you need to ask yourself when considering a high frequency coil is “What is my desired target range?”
This is because higher frequencies are better suited to low conductive targets.
As you can see this has literally thrown the first spanner in the works, because most times we detect hoping to find anything ranging from high to low conductive targets.
Soil Conditions
Therefore let us assume we have difficult soil conditions, but how can we clarify difficult? I believe difficult is best summarised by the five categories below.
Difficult – Mineralised.
Difficult – Magnetic.
Difficult – Conductive.
Difficult – Iron contamination.
Difficult – Trash contamination.
There is no one singular type of difficult soil – everyone has their own take on this phrase depending on their sites. So when would it be the best time to use the High Frequency 9 inch round coil, or indeed any HF coil?

New Detector Network – ‘A Treasure Unearthed for Detectorists'
www.detectornetwork.com is a new online platform that has recently been launched for both beginners and experienced detectorists to share their finds, advice and learn even more about this exciting hobby.
Only a Bit of Lead
As in common with most people, when asked if they have found anything, the reply can often be “Oh, only a bit of lead.”

Roman Lead Ingot Update
I would just like to update readers of Treasure Hunting magazine with some further information about the Roman lead ingot I found back in September 2019.

No More Moon Boots?
In more than four decades of detecting, the weather and varying soil conditions have all had a huge influence on the level of my enjoyment of this noble hobby.
My A-Z of Detecting

Lost and Found?
There have been several instances over my long detecting career where, not only has it has been a delight to be able to help people who have lost things, but also a great thrill when such losses are returned to their owners. I have several memories of such occurrences.
