People often forget about factory reset functions since it is still a rare feature. I am a proponent of resetting newer generation digital metal detectors on a regular basis, especially if settings get changed around a lot. The more setting changes are made, the more chance of a programming bug slipping in and messing with the operator. This is the procedure for the many F75 variants out there. From the F75 Owner's Manual page 10: RESET function The F75’s microprocessor saves all settings which you input, even after the power is turned off. If you wish to reset the settings to the factory preset, follow this process: Turn detector off. Press-and-hold the red MENU button and push-forward-and-hold the TOGGLE SWITCH. Turn the detector on, while you are still holding the controls. Release the MENU button and TOGGLE SWITCH. See the F symbol. When the F disappears, the detector is reset. Note: some latest F75 versions may show five pairs of number instead before displaying the F - the ten digit serial number. All settings have now been returned to factory defaults.

Hi all, I'm new here. I really like this site with all the great advice. I read Steve's detector reviews. Excellent stuff... I'm new to metal detecting and would really like to get into it. I'm foremost interested in nugget hunting, but also general detecting in the parks and on the beach. After reading all the reviews here I'm thinking of getting a Fisher F75 LTD. I'm a fairly tech savvy person, and learn pretty quick. I'd rather spend more in the beginning and have a good machine to grow into. But I read some opinions that the F75 might be too much machine for a beginner. So I'm asking the experts here if I'm better off with a Fisher Gold Bug Pro or a Fisher F19. I would welcome some input. Thanks! Herb

I'm attaching the manual (downloaded from Fisher's site). (Edit: see Steve's link in his response below.) On page 9, bullet point 4. it says: Still holding the GEMINI-3 parallel to the ground, slowly turn the balance knob (with arrow) on the three-piece handle counterclockwise until you get silence (null) and zero meter reading. My question is this: is the knob actually doing an electronic adjustment (such as being attached to a variable resistor or capacitor) or is it just re-aligning / repositioning the transmitter/receiver/attachment rod to optimal location?

Also called RF detectors and depth multipliers. Invented in the 1930's by Gerhard Fisher (founder of Fisher Research Labs, now part of the First Texas conglomerate), this type of detector seems to not have changed much in operating characteristics in 80+ years. From what I've found there are still three competing models in production: Fisher's current Gemini-3 model (now 30 years old) https://www.detectorprospector.com/metal-detector-database/fisher-gemini-3-r27/, Garrett's Treasure Hound Eagle Eye Depth Multiplier (quite a mouthful) which is an add-on to their aging GTI 2500 standard style metal detector https://www.detectorprospector.com/metal-detector-database/garrett-gti-2500-r44/ and White's TM808 https://www.detectorprospector.com/metal-detector-database/whites-tm-808-r38/ , a spinoff of a collaboration between White's and Discovery, another Sweet Home, OR company that appears to now be defunct. The Fisher unit, operating at 82 kHz, seems to be the most closely aligned survivor of the early design. Garrett's 'latest' depth multiplier (easily the most expensive at $1300 retail when combined with the GTI 2500) with its 7.2 kHz operating frequency advertises its advantage of being in the VLF range, ignoring ground minerals. White's unit (operating frequency = ?) has ground cancelling controls. Unlike today's deep PI's and ZVT which can also go deep, these 2 box transmit/receive (T/R) detectors ignore small objects -- an advantage when the sought after target is large and in a trashy area. That's a brief overview of the current commercial climate, but what I'd like to know is how much different these three units are when it comes to operating characteristics. Specifically do the differences in operating frequency and/or ground adjustments translate into better performance under certain conditions?

Is a fisher M97 a good metal detector? One was just given to me. I am wanting to get into metal detecting with my grandson.

Fisher F75 Special Edition DST | F75+ User's Manual, 5.06 MB pdf file, 48 pages Note there is some confusion regarding the Special Edition (Black) as generally being referred to as Limited or Ltd models in most advertising since the Special Edition is just a color version of the Limited. The Fisher F75+ is also another version of this same detector, sold with different accessories.

I am collecting manufacturer catalogs and user guides into the Downloads section of the website. I am building a Metal Detector Database and want to be able to link to manuals that stay in permanent locations. It also makes it easier for members to find manuals from various sources all in one place. I was unable to find reader versions of the manuals for the Fisher F75 DST, Fisher F75 Ltd DST, and Fisher F75+. The versions available online are set up for printing and the pages are out of order for reading on electronic devices. I carry all my manuals on my phone or iPad these days, and so reader versions are more useful for me and I suspect also for others. So I took the time to reorder these documents into reader forms for download. The pdf reader version of the basic F75 with DST can be downloaded here. The pdf reader version of the F75 Ltd with DST and F75+ (they are the same detector) can be downloaded here. All the Fisher manuals and catalogs I have uploaded so far can be found here. I am adding models daily.
