Brand New F75+

Hello all,

Brand new to detecting (though have a few friends that have dabbled) and have picked up an F75+ through their introductory package bundle...

Should have it in a few days. Hope to be posting all sorts of treasure finds here shortly afterwards (haha!)

Appreciate any tips/tricks for getting started...already buried a bunch of stuff in the back yard...though I hear Canadian coins can be tricky....

Welcome to the forum and the wonderful world of metal detecting.

The first thing you did right already, you got a nice machine coming that you can grow into as you get more skilled.

Now when your machine comes in you will have some controls that you will most likely mess with, just getting to know your machine. Now I have seen a bunch of people get a new F75 and get it all messed up with settings.

So I would suggest getting the manual out and find out how to do a factory reset to the machine. Then if you get to the point where things are not acting right, just do a factory reset and your machine will be back just like it was when you turned it on for the first time. Just to let you know most of the time it is setting notches that gets the machine screwed up. So I would suggest staying away from notches until you get the basic machine operation understood.

The next thing I would suggest is looking up how to do a ground balance, this is something you will want to do before you start hunting any area. Then I wouldn't start hunting those items you buried in the yard, I would think you would be better off with just putting a few items of interest on top of the ground and spend some time with you detector swing over them just to get the feel of the sounds and to see what comes up on the meter as ID. Also that would be a good time to try some disc settings.

If your machine comes with a small coil, that is a good coil to work with when first learning the machine you will have less targets under the coil at any one time. Now don't get me wrong that little coil is also a very good hunting coil and is not just for learning.

You can down load a manual and start your reading while you wait on that new machine.

There is a bunch of guys out here waiting with help if you need it.

Good luck,

Ron in WV
 
GrantT, congratulations on the new F75. Everything Ron in WV said is correct. I might also add to not set the sensitivity too high. Some people set it in the upper 90's thinking that they will get more depth than they will get in the lower settings of 50-70's. Start out with the sensitivity in the 60-70 range. This will help the detector to run more stable and avoid frustration of excess noise. After gaining a fair amount of hours experience, try turning up into the 70-80's range. I have used the F75 for many years and I usually hunt with it between 87 and 90. I have found that anything above 90 causes the detector to be too sensitive to EMI and falsing. Many people get frustrated with noise,falsing, and junk targets and give up detecting after a few months. Digging junk along with learning the different noises is your "learning curve friend" when starting out. The reward will be the increase of good finds as you begin learning the machine. Stick with it and good luck.
 
Thanks for the replies and suggestions and direction. Looking forward to some experimentation.

To be honest, not in the ideal location here (Edmonton, Alberta) for metal detecting in terms of historical finds etc, but lots of school yards, playgrounds, sports fields etc. Also plan on bringing it to Mexico to do some beach hunting so have been doing some reading about getting some salt water/sand use of it as well...though lots of dry sand beach where we go as well (mile and miles of it).

The 75's love coins and the spots you mentioned are good locations. Some of your coins are of different composition then ours, so they may read and sound different. Lay a few out on the ground and see how they read and sound. Good luck and enjoy a grand detector.....and when the time comes, get yourself the 5" DD coil for the heavy trash spots. HH jim tn
 
GrantT,

I have a WORD document of several posts and threads with F75 info from several forum members. If you want me to send it to you, e-mail me at therover61@aol.com. Just make the subject line F75 info so I know what to look for.

Yes, I have read that Canadian newer coins are a particular issue for many.

You recommend the 5" DD coil, and I've also watched numerous reviews of the Magic 5x8 from MGC which is quite inexpensive, but seems to pull nicely....and comments on which?

John....email coming immediately!

Arrived today...should have taken the day off. :clsoedeyes: Could of been playing already instead of sitting here behind a desk!!

Hehe....my first find, no less than 10 minutes out of the box. A week or two of advanced reading and watching YouTube videos before delivery and I already feel very comfortable with the 75.

My wife tossed an old Canadian quarter in the yard earlier in the day so I would have something to go find...but I ran into this very strong signal first...1" down in my lawn. Not sure where it came from, but found with the detector, and a quick pinpoint with the F-Pulse and out it came.

Looks like a cotter pin...made out of metal so you're a successful metal detectorist!
So you know the thing works now and as you form a relationship the better metals will begin to show up.
 
Went out to the field behind our office today at lunch (there is a sand volleyball pit and lots of grass) to do some testing, and first thing I noticed was that I was not able to ground balance.

As per the instructions/videos, I hold the detector coil up about 3' in the air, push the toggle switch forward (machine says "pump coil") but then after a few pumps up/down it comes back with the can't balance message. Tried it over sand and grass.

Any ideas? Factory reset and tried again....same thing.
 
Grant,
Could be you were over metal in both places, or there is no mineral present to balance the detector to.

Use the pinpoint and find a quiet place to try again.

Hold the detector up with the coil away from the ground then switch over to Motion All Metal. Now push Menu button down to Manual G.B. and turn the settings knob to see if the Ground Balance is indeed working. If the settings DO change manually, keep it in Motion All Metal and scan the ground for a spot that has no targets. Now push and hold the switch forward and pump the coil 4-5 times. This should allow to detector to Ground Balance. ( Do this in Motion All Metal and "not" in Stat all Metal )
 
Thanks for the suggestions...no go.

Tried numerous times in numerous locations....whatever number the ground balance is set to just never budges. From factory reset (90 I think), I have tried a few spots and the numbers just don't budge. I can go over to all metal/motion and manually change the numbers (it seems that it wants to drop down to 25? before the sounds pumping up/down will sound roughly equal - I think that is how you do it, yes?) but any time I try to have the machine do it, the numbers don't budget and immediately go to "can't gb"
 
Most posts on Ground Balance problems that solved the problem say that the upper coil wire connector can be unscrewed all the way off then make sure the plug is pushed all the way in, then retighten the knurled connector ring until you feel it stop. Also taking out the batteries and reinserting them may help.
 
Just another update. Hooked up some headphones (better sound until my "real" ones show up) and using the MANUAL ground balance technique, I found that if I brought the GB down to around 30, I got nice, quiet, equal "tones" when pumping up and down.

So, reading that the F75 will not GB below 40, is this likely the reason? How common is a GB number of 30? I could still be doing something totally wrong....

I'll try disconnecting the coil, pulling batteries, and reassembling etc a bit later and see what happens....thanks for the suggestions! Willing to try anything at this point.
 
Coincidentally, I had ordered a MGC 5x8 sniper coil and it arrived here in the office this morning. Based on the advice of miserman, I pulled the batteries for a while, but I also put on the new coil.

Ground balanced immediately (46) after reassembly.

So, later I'll go back to the factory coil and try GB again as well. Battery pull might have done it! Will let you know.
