Some claim many have passed the V3i; however, I have found none that provides adequate information reflecting they are 'simultaneous' on the display
indicating the freq. in scan, pinpointing, and in performing an Electro Magnetic Interference (EMI); likewise, the V3i When a single frequency mode is selected you will also see an option called Normalized c/p By checking Normalized, all VDI’s will be noramalized (shifted) to a common frequency. That common frequency is, for historical reasons, 6.592kHz, meaning the US silver quarter will have a normalized VDI response of 83. With Normalized unchecked, V3i will report the raw VDI numbers for the frequency mode selected. There is at least one situation where this is an advantage. At 22.5kHz the lower part of the non-ferrous VDI range is expanded, resulting in more numerical separation of low-conductive targets. This can help in separating nickels and jewelry from pull tabs. VLF detectors attempt to identify targets based on their phase response. But different frequencies result in different phase responses for a given target, so the VDI scale was created to present a normalized response, such that detectors of different frequencies would have consistent outputs. That way, users don’t have to remember a lot of different response scales Ante.
c/p Discrimination can also be set to accept or reject predefined icon ranges. Icons can be user-defined to certain VDI ranges, such as a US nickel to +18 to +23 (see Chapter XX). Then, using VDI Selected By Icon, that icon range can be wholly accepted or rejected. When this method is selected, an Edit box becomes available, and each icon range is listed with a check box. Ante.
As if the V3i didn't have an arduous learning curve the fact now one must 'simply' guess what the freq. is; ergo, the operator states 'my detector is chatty'! Imagine that!
To consider the totality of the facts: White's Spectra V3i could not possibly be outdated! (most is copied and pasted from the beautiful White's Spectra V3i manual and the advanced-user-guide).
Now that Garrett has acquired White's perhaps, they will put out a newer version of the V3i? ? ?
