 F75 LTD Field Test Gene Scullion Badger Metal Detectors

A proto LTD was on my doorstep when I got home Friday night, and I couldn’t wait to give it try Saturday morning. I put it together, did some air testing, and was impressed with what I saw. It didn’t blow my socks off, but I live in a very new neighborhood and all the utilities are buried here, and it negatively affects every machine I test here in my yard. But that said, it is a relative test, and it really only to gives me rough idea of how good a machine is. Plus, it is drier than heck here right now; we have not had any significant rainfall in over 4 weeks. Ground is brick hard so I knew that would affect things as well. The test bed I have in my yard is no good indication either, as I know it’s affected by EMI in the area.

Two of the three places I wanted to test this at were still in standing corn, but I knew that couldn’t stop me. All of these sites have a lot of iron and in some places its very heavy. These are sites I have hammered for years, picked clean if you will, with the machines I was using, including the original F75. We don’t have a lot of mineralization here in Wisconsin but I was surprised to see GB numbers down into the 40’s and 50’s. I don’t know if that had to do with the fact that it was so dry because I normally get higher readings at these sites (usually in 60’s and low 70’s). One site is a stage stop that existed from 1832 to 1854, and the last 6 or 7 times there, I found next to nothing each time. I really didn’t want to write this site off as it was one my most productive spots ever. I did find some targets there when the F75 first came out, but after several trips there with that machine, the targets again dried up. This field is no-till, so the dirt never gets moved around anymore. I ended up digging three buttons and two musket balls here, plus a couple copper rivets. The other sites are ghost-town sites, both now cropland. I normally hunt with my Disc at 4, with the two-tone option, and I run the sensitivity as high as I can without too much chatter. In some areas I can run the sens very high, up in the 90’s, but in other sites I may only be able to run at 30. More often, it’s somewhere in between. The sites I hunted this weekend I was only able to run the sensitivity at 50 in the Boost mode.

I did some comparisons with my existing F75 in the DE and JE modes, and was able to determine easily that the two machines were identical in those modes. Some people had expressed concerns that there might be a difference from the original to the LTD, but from everything I tested I am confident the new LTD is identical to the original in those modes.

All day Saturday I hunted in the Boost mode and each time I got a signal I would switch between modes to see how the targets sounded in the DE and JE mode. In every case, the audio was louder, the signal stronger, and the ID seemed “smarter” in the Boost mode. My sense is that because the Boost mode is more sensitive, the machine is able to get a better read on the target and as a result, you get better info on the display. Often with the original F75, in JE mode, I would get some targets that were deep, and often the ID numbers would jump around, and audio as well would be a bit erratic. In the boost mode the numbers didn’t jump around as much, the audio was stronger and cleaner in many cases. I was actually able to tell when I had detected a small nail because the audio and screen numbers were sharper. For example, in iron infested areas, I listen for the high pitch audio that usually signals a target above the iron range, but we all know that some iron can fool a machine and will ring high. Washers, iron rings, larger chunks of iron, and even bent nails can give you a false high ID number and it often bounces. But this indication can also be a good target next to an iron target so you either have to try to separate the targets by rotating around it while you watch the screen, or dig it up to be sure. I have noticed in the Boost mode, as I rotate around these types of signals, it becomes very clear when it’s a straight nail. I may get the mixed audio, iron/high zip, with equally bouncing ID numbers, but as I rotate around I eventually am going across the nail in its “narrow” axis, and then the numbers and the audio give a distinct iron ID reading with full audio low grunt signal (no occasional high “zip”). I dug several of these just to be sure, and every time it was a nail. I like the way the Boost mode enhances the audio and ID indicators. Now, that said, I dug about 4 targets that were solid hits, but they turned out to be the “end of a large nail”. I would pinpoint, dig, and invariably have the tip of a large nail right at the edge of the hole. I believe the larger nails fool the machine even when sweeping across its narrow axis because there is a big enough chunk of iron there. After this happened several times, I began checking the targets in all metal pinpoint and it was then easy to see the target center move from where the Disc mode had shown it to be.

While working in one of the corn fields, I came across a large iron ring at the edge of a corn field. I got the idea to try the Cache mode so I took the ring out of the corn and set it on the dirt road at the edge of the field. This ring is about 10” in diameter, maybe an inch wide band about ¼” thick or so. It was rusty of course. I switched over to the Cache mode and began sweeping across the ring while lifting the coil higher and higher. I was a bit stunned and delighted to be able get the coil to my chest height (over four feet) before I would lose a signal. And this was with sensitivity only on 50!

One site was a wheat field that had be cut mid-year, and then plowed. There were brick-hard clumps of sun-dried dirt and ruts and peaks. I wanted to see how the machine handled this. I was delighted to discover that several targets that gave good audio in Boost mode, at a bottom of a rut, would disappear altogether when I would switch back to the DE & JE mode. Or the signal was so weak that I could have easily missed hearing it. If I brushed aside dirt to create a flat surface to sweep, I could then hear the target, fainter of course, in the DE mode. If you frequently hunt rough terrain like this, the Boost mode will give you an advantage. I made one really nice find at this site, but it wasn’t deep, so I can only assume the plow turned it over and brought it close to the surface. None the less, I can now brag that the first coin I found with the LTD, was a Spanish 1 Reale, dated either 1813 or 1815. I can’t quite make out the last digit, or the first, but it looks like it could be an 1815.

The ground is brick hard at the moment, so I know that is affecting the depth to some degree, but even at that, I dug more targets out of sites that had virtually dried up on me. The audio and TID info gave me sharper and more stable ID information. The Boost mode seems to be better than the original F75’s all-metal mode, and again, I was only at half sensitivity. I didn’t walk over that one, extremely deep target yet, so I can’t tell you that it will hit a coin at any specific depth, and I wasn’t able to crank the sensitivity up very high at the sights I was at (there was some interference) but even so, I am convinced the LTD is a full notch above the original and it will easily add increased depth over the original F75. The three buttons I dug were between 6 and 10”, and the deepest one still had very sharp ID and audio and there was no doubt in my mind that this was a good target. And this was in parched soil conditions.

This is by no means a definitive test report, but more relating what my first experience was. So far, I am very impressed. Somehow Fisher was able to boost the output on this bad boy, and I could see it instantly as I switched back and forth between DE, SE, and Boost modes. I am anxiously waiting for Saturday to roll around, so I can continue to see what this machine can do. I hope to go back to a site this weekend that has better conditions and no electrical interference so I will get a chance to see how it does at higher sensitivity settings.

F 75 Field Test Report by Mark Gillespie

To begin I’d like to explain a little about why I wanted to write a review of the F75. My first detector was purchased by my wife in 1980. As most well know, the machines back then, had very little depth and hardly, if any, discrimination. Since that time I’ve owned three other detectors from two different manufacturers, not to include my present Fisher F75. Being a procrastinator, (in the biggest way) I’d dragged my feet for over a year before choosing the F75. I had read every article and review that I could find before my purchase in March of 2009.
After buying the machine from Badger Metal Detectors (Gene Scullion) I was extremely excited when it arrived. One note worthy quote that Gene stated after I bought the F75 was “you won’t look back.”

This was because he was using the same machine that I was prior to switching to the F75. Nope, I never looked back. I could hardly wait to try it out in my test garden where I had many different coins and trash buried at different depths. Now you might be wondering why I was so excited about the test garden. Well, to be truthful, it was because many of the coins had vanished from detection by the other machines I had been using.

Practically running out of the house to the test garden, and knowing the dime was the smallest coin planted there, I had to try it first. My anticipation and excitement was high when I turned on the machine for the first time. I left all of the settings in default and swept over one of the undetectable dimes and “BAM” the F75 acquired the dime with no problem. I could not believe what I was seeing for a few moments. The dime was lying flat at only 6” deep. I was well pleased and my confidence was high from the very start. As I moved to the other hidden targets they were also easy to detect. Each gave away their location with very little effort on the part of my new machine. Now, a little history about the garden will help to understand my feelings. About two years prior, I had planted the garden without cleaning out all junk and iron targets first. It just so happened, the area was riddled with nails and other typical barn yard material. Shortly after burying the targets, a couple of good soaking rains had caused some of the coins to vanish from detection (by my other machines).

With my confidence high I headed out to the areas where the other machines had given me so much trouble in the past. My first stop was a local community center where I had found a silver dime about a year before. There’s also a story about this dime as well. It was only 2” deep and laying flat. The machine that I was using at that time was not a slouch (I had dug nickels at 7+” before), but was actually one of the best relic machines around, but it only gave a very low volume beep over this target. Thinking it had to be a deep target I dug a 6” plug just to find the dime in the top two inches of dirt. This particular find got me to thinking about why the machine only gave a faint signal. At that time I really didn’t think masking was a factor in the areas where I hunt so I sent the machine in for a tune up because of the very low volume beep on the dime. Two weeks later, the machine came back with a clean bill of health, but I have not forgotten that day. I really felt the area should have more goodies, but couldn’t seem to acquire them with the other machines. Well, anyway, I returned to the same area where I had hunted with the other machine, and within a couple hours had 2 silver dimes, 1 silver war nickel and 2 wheat pennies, not counting the regular clad coins.

A few days later I had an opportunity to hunt at an old school that had been shut down for about 40 years. This is where the F75 proved to be a superior coin and relic hunting machine. This area was covered with old rusted nails and miscellaneous metal parts. Hunting was more difficult because of the many targets in the ground but three hours later yielded 2 Indian head pennies, 1 wheat penny, two buffalo nickels and an antique green stone ring. At this site I was utterly amazed at how fast the machine could sound off on the different targets. I remember getting a good signal, pinpointing what I believed to be a good target and after digging a nice plug 5” deep only to recover numerous nails from the same hole. All the time thinking I had heard a good target for sure, I continued to dig until the Indian came to light. Then I stopped and thought for a moment about what I had just witnessed. There were at least 3 nails in the same hole where the penny was, talk about iron see through, the F75 saw the penny through the rusty nails.

After a couple weeks of successful hunting I decided to head out to one of the local schools to do a little coin shooting. Okay you might say, “What’s the big deal with coin shooting”, Oops! here comes another story. This particular school has the most difficult ground in my area to metal detect. I have hunted it for several years with very little success. Up until now, I didn’t have a machine that would analyze the soil and give me information about the ground minerals. The FEO meter on the F75 revealed to me the severity of the dirt (FEO maxed out) I was trying to hunt. I took a small magnet and rubbing it over the ground revealing small BB size pieces of coal cinder waste that stuck to the magnet. I posted many questions on the internet with no insights as to what to do. Finally I decided to try the motion all metal function. Basic AM setting wasn’t quite what I had hoped for so I experimented with the threshold setting and finally settled for a -2. My final settings were, threshold -2, sensitivity of 80 and a little positive on the ground balance (actual GB was 80 so I set it to 82) and the machine settled down and I began to hunt. I headed to an area where I had previously hunted many times with my other machine. I felt this area was very clean and wasn’t expecting to find much, but was I wrong. Within a few minutes my first 10K gold wedding band came to light. The finds that followed, were a silver quarter and 5 old rings (nothing high dollar) I had missed with the other machines, all within a 30 square foot area. The all metal mode allow me to detect deeper than regular discrimination mode, which was proven by one ring that was a solid 7” deep. Now to drive home the fact that the all metal mode was working correctly I switched to a simple discrimination setting of 6, sensitivity 80, DE mode and 2F tones to find the target response became broken and only a two way response at best. The TDI numbers bounced from low to high in discrimination mode but were very stable and consistent in the all metal mode.

To finalize my review I’d like to tell you about my trip to Holden Beach North Carolina. Prior to my vacation I had read numerous articles on beach hunting. You know, things like how, where and what to look for in both dry and wet salt sand hunting. Armed with many ideas, I spent close to 15 hours experimenting and adjusting in all metal and discrimination modes. My final settings in all metal mode, were, a manual balance of about 1, sensitivity of 90, threshold of -2. I dug many coins in the 4-6” range in the wet salt sand areas. I was quite surprised at not finding nice jewelry, but an elderly gentleman of 84 told me the beach officials had just added about 18” of fresh sand on the beach after a bad storm earlier this year. But I did prove the machine has the capability of detecting a coin at 10” in the wet sand area. While I was there my son-in-law and I made a very simple video of the F75 performance in the wet salt sand. This video can be found on you tube under the name of “Wet sand testing the Fisher f75 at Holden Beach, NC. “


I could go on and on about what I’ve found since purchasing my F75, but as a final note, I would like to say I have found more silver in the past 6 months than the last 5 years combined with other machines. My first Indian head, V nickel, Barber dime and 10k gold wedding band were found with the F75. Recent release of the new F75 LTD will probably prove to be an outstanding detector as well, given time to learn and experiment with the endless possibilities of buried targets one might encounter. My area holds three different ground problems and the F75 has adapted quite well for me to hunt. Fisher has and will continue to strive to provide the best possible machines in the metal detecting world. The F75 is far superior to the other machines I have used in the past and I can say for sure, if a person wants to take the time to learn the machine, it won’t let them down.
