Below you can see the SEF coil compared to the standard T2
The SEF coil has a better standard of finish than the standard T2 coil... note the coil wire has an added shrink wrap for protection
Very soon I will be publishing my field test, lets see if this coil can add extra life to my T2 !
In the field
The snow had finally cleared I was desperate to try the SEF coil for the first time, a quick visit to a pasture
field in north Oxfordshire would be enough time to get a feel for the coil and see how it dealt with wet grass.
I have to say the SEF coil was a pleasure to use, the field
was reasonably free from modern junk just the odd shotgun cartridge or 50. I ran the machine at 75 sensitivity, 19 Discrimination, and 2+ audio.
Iron rejection was faultless, the pin pointing really impressed me for a large coil...bang on every time.
A short 2 hour search uncovered the usual scrap lead etc, several shotgun cartridges, 3 small Victorian coins, 2 musket balls, a fragment of a
hammered coin, a small Roman and a beautiful Gold mourning ring with the owners
name and date clearly visible 1734, we are currently searching local records to re unite this wonderful piece with a family member.
Nothing was deep on this particular session, as the season progresses I'm
sure the SEF coil will turn up something good
My second outing was to a familiar pasture site which has produced some interesting artefacts many years back, however recently it has been very
hard work, if it wasn't for the fantastic views we most probably would give it a miss.
The first thing I noticed was the T2 would not auto ground balance with the SEF coil, this is nothing to worry about you can either not ground balance
the machine and search in factory default mode (which is what I normally use) or switch over to the all metal section which is on the left of the
screen and manually ground balance from there. I have found in the past that quite a few machines have trouble ground balancing on heavily grazed
pasture, perhaps it is something to do with the years of animal droppings.
I used my "Lazy pasture" set up for this particular search which was sensitivity 75, discrimination 25, 1+ on the audio, this allowed me to have
a steady search without to much spitting and popping allowing more time to concentrate on the more solid 2 way targets.
The targets came thick and fast...sadly nothing nice to report only shotgun cases and copper coinage, what really impressed me was the amount of targets
detected in a small space of time, the bigger coil certainly upped my finds rate.
With regards to depth I am sure it is just a matter of time before I find something to confirm the depth advantage of the SEF coil, as for now I am
just simply happy with its ground coverage, lightness and stability.
Many thanks to Mdetectors for supplying the coil at a fantastic price.
I will be adding to this review when I have something to report.
