Whites DFX Users Classroom Forum

So does anyone use the Hotshot coil on the DFX it appears that the favourite coil from Jimmy is the Bigfoot but they are ultra rare over here in the UK,i was lucky to be able to locate 2 of these Hotshot coils over in the UK and they never caught on due to the massive cost of shipping them over to the UK but they really are fantastic coils being 12inches they in theory should be heavy especially when compaired to the Whites coils but they are as light as a feather.

Been running mine in Land 1 which was designed by a guy who is a tech guru and helps Whites out here in the UK and it really opens the DFX to its full potential and with the Hotshot it is not only very deep but also very sensitive on our small hammered coins.

These are the setting for Land1

Land 1 by Malcolm Jubb
target volume - 63
audio threshold - 1
tone (audio freq)- 238
audio disc - on
silent search -off
mixed mode - off (also, i have ran with mm on .... noisy but i think deeper)
ac sensitivity - 75
dc sensitivity - 55
backlight - 0
viewing angle - 25
ratchet pinpoint - on
s.a.t. speed - 5
tone i.d. - off
v.c.o. - on
modulation - off
autotrac - on
tracview - off
autotrac speed - 12
autotrac offset - 1
trac inhibit - on
block edit - reject -95 to -50 accept -49 to +94 reject +95
learn accept / reject - off
recovery speed - 35
btl cap reject - 1
hot rock reject - 0
sweep speed - 18
ground filtering - 4
visual disc - on
icons - off
v.d.i. sensitivity - 85
d.c. phase - off
graph averaging - on
graph accumulate - on
fade rate - 7
preamp gain - 3
2 frequency (best data) - off (for land 2, just change to using both frequencys)
2 frequency (correlate) - off
v.d.i. normalised - on
1 frequency (3khz) - off
1 frequency (15khz) - on

These setting have been used to suit the UK ground conditions and not across the pond,have had the DFX for about 7 years but in the last 9 months has taken a back seat to the T2 that i much prefer to use these days due to the weight but it has been used more and more in the last 6 weeks due to me using it as a hoard hunter with the 18inch Detech coil and this Hotshot.

So does anyone else use this great coil ??? if so what setting do you use and what type of detecting i guess mainly relic hunting ???

Been out again with the Hotshot coil today and i really do like this,its as sharp as anything signal wise and for a 12inch coil it is so light and does not make the dfx nose heavy like most bigger coils.

Depth wise i am finding its about 2-3 inches deeper than the 9.5inch stock coil but its the weight that amazes me,so as the crops are coming off will be out again all day sunday on a 300 acre farm that has alot of roman history attached to it.I will update if i find anything.

Go Mega B Go! Good luck and HH. Matt

I kept the Hotshot on the DFX full time for relic/coin hunting here in the U.S, it produced deeper finds for sure. I like your programming setup, but I always prefer Mixed Mode for the added depth. The noise your experiencing in MM could be from using VCO with the high DC setting of "55", VCO clashes with a setting above about "40", and instead of dropping DC and losing slight all metal depth, just turn off VCO and rely on Ratchet Pinpoint. Also I liked using Modulation "on" to tell the deep targets from the shallow ones, kind of a form of discrimination when combined using the VDI/Signa imfo. For being a 12" Mono coil, it surprisingly performs well in iron mineralisation and on small targets. I switched back to the XLT about 8 years ago, preferring the performance of 6.59 khz over Best Data and single 15khz... and yes, its armed with a HotShot, also a new one in the closet for a backup since they are no longer produced. I recommend a coil cover if you can get your hands on one, the seam on the side tends to give out from wear, had to have my used one repaired by a guy in California before I had located one for backup.

@Va Dave,many thanks for your words of wisdom on the dfx/hotshot combination i will try a few alterations as per your suggestion.Have been out today but the weather was hot and sultry and the land we had to detect was either cultivated ie rough ploughed or rape stubble which is like bamboo canes so although a fair amount of roman and hammered coins had been found it was very hard work but i still enjoyed.

Next week we are back on our hoard farm as i call it as we suspect 2 hoards are on this farm and both from differant time zones,one field is suggesting a roman silver hoard and the other end of the farm is showing a celtic gold hoard,so will be using the Hotshot coil and balso the 18inch Detech coil in both these locations.

Once again thanks for your input.

HH

I'd love one of those Hot shot coils. Good to hear of the weight.

I notice that program has DC Phase OFF. Larry has a post here on the benefits of DC Phase.

I keep reading about your old hammer'd coins and the caches. I'd love to eventually go over with Jimmy Sierra on one of his MD trips and find for myself... Those really old coins are gorgeous.

HH

Dave: Thanks for the beta on MM and VCO. I'll have to give Ratchet Pinpoint a go. I have read of a dealer that mentions using MM and DC settings of 15 to 20 and still getting plenty of depth. I'll have to explore these both more myself as I am still fairly new to my DFX and detecting.

What would a good price be for a hotshot 12 inch coil?

---

Whites dfx and xlt North east Oklahoma let's go treasure hunting!!!

100 bucks is a good price for light use/ like new condition

So am I to understand that the Hot Shot coil can be used on the XLT or the DFX???
Just plug and go?

If you are going to use it for the XLT, be sure you buy the model made for the XLT, they are not interchangeable.

Bells and whistles are nice, but nothing will substitute for the basic understanding of the hobby.

Thanks L.
I have a DFX and I thought I might have been missing something in the translation.

Back out again tomorrow for the 1st full days dig of 2013,will be using the Hotshot coil again as i feel the ground conditions are just right to use it,its been raining for a few weeks and the ground is just moist as it has been sunny for a few days to take the excess water out the ground.We have 200 acres on a mixture of established pasture,new ploughed,and rotten stubble from last year so we di have a wide selection of ground conditions to try out.

Not sure about the ploughed fields as yet as alot of detectors hate the fluffy conditions as i call them when alot of air is still in the soil due to lack of compression and settlement,but i have to admit the pasture has not be ploughed for maybe 100 years so that could be my 1st port of call the site has produced a wide variety of finds the last time of going on this farm including roman,saxon coins and some nice artifacts.

Have always used the DFX and Hotshot in 15Khz but not sure if to try 3Khz for a while tomorrow,if i do and notice some good or bad improvements i will report back with my findings.

Have been out again this afternoon with the DFX and the Hotshot and although found nothing of any age it was a real pleasure to use this combination again,really slowed the swing speed down and found that it helps to find to really lock onto very small items which for a coil of this size is nice.

It still blows me away how light this coil is to swing as usually a 12inch coil tends to make a detector nose heavy but this is not the case,was still running it with AC75 although i could of cranked it up a little i felt that why is it was running so smoothly why change the settings but i guess it could go up another couple of notches then i feel it would start to run erratic.

If the good weather runs into this weekend will try another local permission that has just had a few fields ploughed and rolled,it was nice to get out as it has been the coldest March over here in the UK since the early 60s.

Does anyone have any input on sweep speed using the Hotshot coil ??? although i have never had a fast swing speed logic tells me i am doing it right but as yet i have not changed any settings on the detector to compliment the slower swing speed or prehaps i dont need too.
