Fisher F75 vs Minelab Explorer SE PRO

[CoilFisher]

Both comparibly priced. Both hot detectors.
The Fisher F75 in one corner the Minelab Explorer SE PRO in the other.

the one with 28 frequencies of course, hands down......

The one that won the GNRS a couple of years ago?

Yes there is a difference in broadcasting: The Minelab purports 28 frequencies or bands whereas the Fisher F-75 sports a 13kHz single frequency.

Does this mean better for the Minelabs? (Silver is supposedly better detected at lower frequencies.)

Purports is the right word.

Multifrequency uses square waves created by taking a sine wave and adding harmonics.
Harmonic use increases sensitivity to iron and E.M.I. More power is required for equal depth plus single frequency has the advantage of all the transmit energy being concentrated at a given frequency which improves depth for specific targets.

G.N.R.C. has always been won by single frequency detectors. Nautilus won every year but one when Tesoro inched in. Recently First Texas took the crown.

The advantage of multifrequency (or twin/triple) is on wet sand where it really does make things much easier.

yes, and I thought my Fisher CZ's did good on the beach, until I got my Minelab Sovereign GT.....

One heck of a post Brian! And especially about the harmonics, without them there would simply be an electronics futility.

Tiggar, strangely enough I discovered the opposite with mine, I thought my Sov did well on the beach until I got my cz-70. I traded the Sov for a $1000 Browning A-Bolt 338 mag (with scope) and thanked God for the sweet swap. It bagged a fat deer this year.

I still have the CZ, it's the deepest detector I have ever owned or seen on Oregon high salt/high black-sand beaches for coin hunting (running in zero notches), period, no exceptions.

One outfit down in the deep south somewhere quit pushing Nauties after the F-75 whupped the Nauties so severely in the GNRS. Now he pushes Fishers. That's what I was referring to about he GNRS. Of course most detectorists know that already, but I thought I'd mention it. Basically it all comes to "the proof is in the pudding".

You all have a fun-wun.

Which would be better on deep silver however?
We have a 13kHz Fisher vs a Minelab that purports 28 frequencies with a supposed active frequency at about 3kHz.

 

[LuckyLarry]

Nobody will answer that correctly CoilFisher because there are way too many variables.

Minelab owners will say theirs are - because of their multi-filters, and "they simply are Minelabs". Super-low VLF'ers will say theirs works best on silver, and Fishers will say theirs are simply because "their" detector is a Fisher, or that too many frequencies slows things to much and targets are missed (which is partially true). Generally speaking though, lower freqs do better on silver/iron and higher freqs do better on gold/semi-precious metals. There are exceptions though, but super low (2-10) will usually work the best, unless the are underpowered (low gain) to start with. But that's only the beginning of the discussion.
