Does it cover more ground,go deeper,find smaller targets? Looking at chart seems covers more ground.How does detector unscramble so many targets on the 28 frequency chart?
Fbs only processes 2 frequencies not 28.

The picture is a very bad representation of what is going. It doesn't matter the operating frequency of the detector. The search field always goes deep enough, even for the single frequency detector. A CTX-3030's search field will hit a 12" dime the same as a a low-end single frequency machine will. The biggest difference will be that the CTX-3030 is more likely to detect the very weak response field of the deep target than the low-end single frequency detector.
Multiple frequencies are most useful in target identification and counteracting conductive salts in wet sand. It won't get you more depth necessarily. You will get the most depth using a single frequency best suited to what you are hunting for with a slower swing speed. If silver coins are your game, low operating frequencies are what you want. If you want gold jewelry, higher frequencies are what you want. If you want relics, somewhere in between is a good compromise.
Maximum depth is best determined by how good your ground balance is, how good your coil null is, and how much of the signal you are whittling away by over-discriminating - and most important - how good your machine's signal processing software is. You do get depth bonus based upon frequency depending upon the metal you are looking for. You have a better chance of finding deep silver using a low frequency. This, however, is only a small component for depth compared to balance, coil null, and processor
Why does the FBS find the deep silver where other machine do not? It is mostly due to the machine's signal processing software - which is really, really good.
_+2I thought that fbs recieves and processed 3 frequencies at once. Low me and higher and the noise cancel slected which frequencies to operate on

Agree with most of this except the low freq for silver, it's dependent on the size of the silver, big silver is a high conductor, small thin silver is a much lower conductor and is better found with higher freqs.
The detector has no idea what the metal is made off.

In my test garden, which is matured for 2 years, I have found the following with my V3i.
On 6 inch coins Nickle, dime and quarter in the coin and jewelry mode running 3 frequencies it hits and ID's all three no problem.
On the 8 inch I can tell there is an object there in 3 frequency but not a good repeatable signal. If I switch to the lowest frequency, the dime and quarter hit strong and repeat about 75% of the time. The nickel almost disappears.
If I switch to the highest frequency the nickel comes in pretty strong and the dime and quarter id drops to less than half.
The Deep Silver program on the V3i runs only the 2.5kh frequency and it does hit deep. I can easily pick up a 10 inch quarter in the test garden.
Where the multi frequency machines shine is in salt water and mineralized soil. The V3i runs great on wet salt beaches....just don't take it for a swim.

This is the main reason to always run in stereo-mixed mode if your headphones support it. The AM channel will almost always pick a coin up in this situation, where as the DISC channel may produce a choppy signal, or no signal at all. I have pulled several 9+ inch dimes since I got my V3i, and the only reason I knew they were there was because the AM channel noticed.
ok now you guys are making sense to me ,i only hunt salt water beaches and i appreciate the stability of my cz21 in the wet sand but for dry sand and super black sand dry sand the multi freq detectors seem so much slower and less accurate than my single freq detector [at pro] ,my point being other than the ocean what are the advantages of multi freq
