A detector that does not like Bottle Caps?!?

[Seanpaul]

I'm interested in hearing from users of different machines about the tendency of their machine to like or dislike bottle caps. I just got a Teknetics G2 and while a great little detector, the darn thing absolutely loves bottle caps; rings out solid on them and gives a good VDI like coins. This is a bad thing, very bad for my type of hunting in trashy parks. I can deal with tabs and other trash, but putting up with tabs and bottle caps is a bit too much. My previous detector, a Whites DFX did fairly well in that department, often coming up with a VDI lower than coins and would lump bottle caps with zinc pennies. It was not always fool proof, but for most of the time I wouldn't dig a bottle cap unless I wanted to with that machine.

Any other machines out there that hate bottle caps, lump them away from most coins and just flat out, more often than not, let me know that there is a bottle cap down there instead of a penny, dime or quarter? Thanks for any information you can give.

Hey Sean my f2 likes those too. I'ts a flip of a coin sometimes to dig them. Sometimes I think to find the good stuff you have to clear the trash.

Fisher CZ 7A Pro loves them too. High coin/Penny all day. But as a relic hunter you gotta dig em, could be a deep belt buckle or old silver! Sounds really annoying in a trashy park tho. If they are shallow they should pinpoint larger than a coin tho.

I'm actually not surprised the F2 likes them, my G2 is practically a kissing cousin to some of the Fisher line and there is bound to be many similarities and/or programming that is shared. I have done a little research and it seems to be a problem for vlf machines of the 2 filter type of discrimination; that seems to be what is more common on a lot of the machines out there nowadays. Some of the Whites, with 4 filters and adjustment for bottle cap reject look like they do better with bottle caps.

Oh man, you have no idea around some of these parks. It's like bottle cap graveyards or something! Yes, they do give a wider signal but so does a shallow coin, especially the quarters.

My E-trac hates bottle caps. They always give a scratchy sound and never sound as high pitched as silver or copper. They're easy to weed out. The numbers can go high if the cap is huge. I still dig some, but I'm mainly a relic hunter so it doesn't bug me to dig trash.

I also used a White's MXT and I almost always knew when it'd be another cap. The rusty ones on the 6x9 DD coil sound like quarters but they're easy enough to figure out after a while.

Nothing sounds as sweet and round and smooth as a deep bullet! I almost always know when its a big old piece of 150 year old lead under my coil

I totally agree on relic hunts, I would dig most signals as well. I don't know how many bottle caps you encounter on a relic hunt but a park hunt is probably different. The first park I stopped at today I dug, give or take a few, about 20 bottle caps within about a 8' square area and this was not by one of the trash cans(that apparently don't get used). Every sweep was a good signal and I thought I had a bunch of different coins on the ground, instead bottle caps to my dismay

You're spot on. A bullet signal is very different sounding than a bottle cap. They sound smooth and round just like you said. Like a good coin signal. Trash just tends to sound worse.

I can always tell bottle caps with my V3i, using 3 frequency and the great signal analysis the V3i incorporates, thereby seperating the good, the bad and the ugly. I hunt predominately at parks, schools and tot lots. With the correct coil, navigates through those trashy areas where others fear to tread.

My At-pro give a scratchy signal on them in pro mode,pretty easy to tell most of the time.No matter what machine you have your gonna dig some trash now and then

[DIGGER27]

My Vaq and a concentric coil can tell the steel ones from coins because they sound slightly different and will disc out before I reach max disc.
Using a 10X12 DD coil, they usually won't disc out and they also sound just as good as a quarter most of the time.

Zinc and aluminum ones will break up a lot of times using the Tesoro shake with the concentric, less with the DD.

The F2 has a difference in the tone between high tone clad and the steel ones.
Coin and other good targets have a sharp end to the tones where the pop tops usually do not.

The zinc and aluminum ones sound pretty good and it is harder to tell, but after digging a few I notice the numbers and since they are not usually normal coin VDI numbers I can usually avoid them with a high degree of confidence.
Still dig a few from time to time to be sure on hunts where I don't feel like digging everything.

The Compadre is pretty much the same deal as the Vaq with the concentric coil.
Most wont ring true with a sharp edge to the tone, but life isn't always that easy and I have been fooled on occasions using all of these detectors and coils.
I am usually a dig it all hunter for a reason.
That is the only way I can be 100% sure.

I can hear a bottle cap easily with Sovzilla. Gives kind of a wavering tone at the edges, not solid like those darn 40 oz tops!

You just need more swing time...you'll be able to tell the difference after a while.

Bottle caps usually ring in at 70-72 on my MXT Pro. Copper pennies are 77, dimes 79, etc.....I usually don't dig the low 70's b/c it's always a cap.

I can usually pick out bottle caps (unless they have been folded in half) with my AT-Gold.
It gives a nice little _-_ low high low tone.

[BentRod]

Most of the time my BH will usually tone them out as a broken scratchy sounding, like it's trying to disc it out....doesn't stop me from digging them though....because JUST IN CASE.

I just think its going to. Be more of a challenge and learning curve. My dfx would put them in the upper 60's to low 70's so I rarely dug those and the coins came in mid 70's and up unless it was a zinc penny and those were bottle cap range. Thanks for all the input everyone!

This will work with just about any discriminating detector.

Once again, thanks for bringing up a really useful older thread!!

[HuntNGold]

My AT-Pro loves those things I normally get a very solid signal from them and I dig hoping it to be a coin but get dissapointed to see a bottle cap.
