GT light -w/concentric coil on the beach.

[DonNWF]

I went to the beach this morning with my GT light. No meter, no S-1 probe just my new 8in concentric coil. Time on the beach 1 hr 35 min. I got this coil to use in high trash areas on land but I'm now thinking its going to replace my 10in Tornado that Ive been using as a beach coil. Why? I can really move out with it .and it is hot.
Results - the usual beach stuff. The only reason I'm including a photo is so you can see the size of a sterling ear post and a little silver charm (compare them to the pop top). Both came in loud and clear. The little ear-post has a black stone setting and sounded as loud as a silver quarter, and it was deep. I don't think the 10inch would have found it any better. Things I noticed:
Falsing - almost nil. Only happened when I lifted the coil off the sand too fast when changing directions.
Sensitivity - At 12 O'Clock I picked up surface cans at 12 inch distance with the coil flat on the sand.
Pin-point - excellent. The strongest clearest signal always centered.

I know the knock on concentrics is that you have to overlap your swings to get coverage comparable to Dbl-D's. Well I think yes and no on that one. In the dirt I would be thinking about good coil control anyway. On the beach, more sand - more targets. I don't see this coil missing much moving down the beach. Smaller coil on the beach? Why not? Its light,its waterproof. its hot. HH

Thats a good report on the concentric and I thank you for it. I have been
wanting to get one but haven't heard any real reports on them. This is the second one I have read on the 8 inch concentric and both are positive.
Having owned a Fisher CZ with a concentric coil it worked very well in my area and coverage was never a problem but had many a good keepers with it.
I feel that if you like it and it works for you, its a great Coil.

What if you used your 10-in Tornado coil, without the other stuff? Maybe the same results would have been found.

p.s. Where did you get your concentric coil? I saw some advertised on the Kellyco website, but I couldn't figure out how to order it. I think I would prefer the 10-inch, only for its size, but I am not sure yet. I should have just called them to see. I will wait.

I have used the 10in without other attachments on the beach, I just got tired of disconnecting all those cables and I have found similar small items with it. I would say that the depth on recent ear post was at least 10 inches. I scraped down with my boot at least 6 inches and then took sand out with a scoop. no target. The coil said it was still in the hole. Next scoop got it. But it was so small it went out with the sand. I used the C-coil to find it, just by getting centered over it in disc mode. I know I couldn't do that with the 10in without switching to pinpoint. The strong signal I got on this small ear post with a smaller coil impressed me.
BUT this is all relative to my sand and beach and how I like to hunt.

I just received the Excelerator 8 inch concentric coil.I'm going to use it in a park tomorrow that usually produces silver.My first impressions the new coil is really a 8 3/8 inch coil and more heavy than the Tornado 800 7 3/8 inch coil.The ID meter bounces a lot more not as solid as the Tornado.The sound isn't as crisp or sharp with the zing on targets in my coin garden compared with the Tornado.I'll see in the field tomorrow.

Especially interested if you have to change any of your usual settings. Also give us your regular setup . Meter? Probe. etc.. Got a 1941 Wheat with the C-Coil yesterday. I have some additional observations to pass on and looking forward to yours. HH Don

Don,I really wanted to like this new coil but here are my results.The Excelerator Concentric was compared with a Tornado 800.As you know on the Sovereign Mod web site this Tornado 7 1/2 inch coil came in next to last only ahead of the old BBS 8 inch coil.Conditions 50 degree weather well sodded 1950's park that has produced a lot of silver coins that I have searched with at least 40 different units.The Excelerator coil was used on my XS with no mods which also has a Night Hawk 180 meter and Sunray probe installed.Headphones were used with the sensitivity at 75 percent.I used the concentric coil for about an hour and half before switching back to the Tornado.First impression heavy my back noticed the extra weight even with the straight shaft.The target response isn't as sharp,the meter bounce is still too noticeable,and takes more time to lock in on a final ID number.During the use a lot of iffy targets dug a lot of screw caps.Overall more erratic with a smaller narrow scan than the Tornado.I found one memorial penny at a bout six inches good sound and the ID locked on 180.I switched back to the Tornado 800 and re tuned the meter.I went over the same area the sensitivity still at seventy five percent.The Sovereign now with the Tornado was silky smooth, had a wider scan,and better ID lock and much lighter.I found twenty three coins in the next two hours 3 clad quarters 2 clad dimes and 17 pennies,which 4 were wheat backs and a 40's Canadian cent.The deepest coins were seven plus inches.Summary the Tornado 800 will separate targets as well or better has a wider scan,more stable which in the field finds more and deeper coins.

When using the C-coil did you have to change any of your standard settings to get your normal hunting response?

Your setting of 75%. Is that at the GT 9-10 O'Clock position or equivalent?

Just for a comparison between your Michigan and my Florida dirt. My usual GT settings are 11/12 O'Clock Sens. Threshold - midpoint or a Little less. Your usual setting are?

I find that I get a very high return tone on all non-ferrous targets followed rather quickly by the threshold buzz-tone within 5 inches after passing over a target. Multiple targets at different depths under the coil circle will sound off when passed over. I think, do to the cone shape coverage. I couldn't get this with my 10 inch with trash and good stuff close together, without very precise coil control. Nay-be I should have gone with an 8 tornado to begin with but I like the 10 in coverage.

I have no other 8in coil to compare the C-coil against so your test results may influence me to look at the S-8. But the C-coil performed great on the beach and I'm sticking with it there. There have been rumors of other C-coils coming along for the SOV.

Thanks Ron for review. By sharing info we all learn something. HH Don
