BOTTLE CAPS! What are YOUR tips ?

Jim, you are not the only person fighting the bottle caps. I second guessed myself more than once when I gave up using my MXT for the F75 because of the bottle caps. There have been several posts in this forum with some workable ideas. I would recommend doing a search for "bottle caps" and see what you get. Here is what I do to defeat them most of the time. I still get fooled sometimes though.
- The first indicator I use is the FeO meter. A bottle cap will often raise the FeO meter, while the confidence meter goes down.
- A faster sweep across the center of the target several times will often result in a wide number spread on bottle caps, while coins, silver and gold jewerly often stay consistently within a small number spread.
- Try switching to the non-motion STAT mode and sweeping that over the suspected bottle cap. Make sure you fastgrab very regularly in the STAT mode...like alot more than you think you should. The non-motion STAT mode tends to spread the numbers on bottle caps pretty wide, where again, coins, silver, and gold tend to have a rather consistent number.
- Some people have mentioned that running the coil forward and back over the target instead of left to right will cause sort of a grunt at the beginning or end of the signal. I have not tried this much, but probably worth a try.
- After all that, if there is any doubt, well, you should probably go ahead and dig it. I have found that some bottle caps, especially in the all metal motion and DE and JE mode registers just like a good coin target. The BC mode does a pretty good job of breaking up or eliminating bottle caps, but it also does a good job of eliminating any gold rings that might be there too.
Hopefully Fisher can fix this love for bottle caps in the future. I know it doesn't have to be that way because my MXT rarely hits on a bottle caps. This machine hits them hard. Of course my Fisher F75 has much better depth, sensitivity, and is lighter to use than any other detector I have ever owned, so I'll just keep using my Fisher and dig a few bottle caps along the way for most of my hunting. Hope this helps. Jeff

Thanks Jeff and Hi
Man, I had to read and re-read that several times. Some real pearls there on using the machine and what to watch for. I will have to spend more time with the Stat feature and FeO meter. Not too technical, but overlooked features that can give more information.
You are right on how hard the F75 hits 'caps. The different types and metals used seem to have no rules but there really are some rules to help ID them.
Gotta love those repeatable tones and numbers!

Imported from around the world. Beer, wine, soy drinks, soft drinks, you name it, and each seems
to be made of a slightly different alloy that reads different than the others.
I'm going to run them through
reverse electrolysis using salt as the electrolyte to rust them up good and fast, then bury them to see
how they read. [Also brought back Samuel Adams, Australian, Irish, & San Miguel from the Philippines.]
Should be interesting.
