In detectingMO's youtube video on his school hunt, he has trouble trying to ID nickels, as the ones he found at 4"-6" didn't lock on and the signal traveled the arc even into Iron.

I noticed the same thing on the area of nickels, or even a piece of foil or a flat pull tab. While the LRP locks onto any coin from zinc and above to the 9" depth, I am finding it's not so with nickels.

I have been communicating with Jorge at FTP about this. He suggested that I do an air test (inside, but even better outside) and try a quarter and move it back and forth over the coil, starting close and slowly moving away from it, and watch the numbers to see when the quarter numbers start traveling into other segments. I did this, and a quarter hits 78-80 almost 5 out of five times until I finally lose the detection of the quarter. This is a good lock.

With a nickel, I can get 5 out of five times till I get about 3" away from the coil, and the nickel starts being detected anywhere from Iron into pull tabs, even a silver hit occasionally, and 2-3 time out of five at 4-5" and by the time I am at 8" the nickel might hit 2 out of five. This is not a good lock.

Could other LRP guys try this an see if they are getting the same results? Jorge was going to do the same test and we were going to compare results. I thought I might be helpful to get more info on this from other users. It may help nail down a software issue, coil issue or my sanity issue.

Thanks.

Hightone.....I'm assuming you used the 11" dd coil, but what mode were you using, & what sensitivity level ?
just thinking we should all try to use the same setup.
Super Thanks for your efforts in this.

I just tested mine. I was using the 11" coil. I have it set wide open. 10 sens, 0 disc. I tested all modes. In mode 4 I was getting a solid number up to about 5.5-6 inches. After that The numbers and the tones started to jump around, but mostly down to foil range and about to 27. When I got up to about 8" I would get the occasional quarter reading. when I tested it in the C,J,A modes I would get a solid tone and number until it got out of range, which was just above 6" Much better lock on, but less depth.
Hope this helps a bit.

The deepest disc mode is 2,3 and 4. I used Mode 4. C,J and A, like Bucksport experienced, is about an inch or so less in depth. I addressed this in my review a few months ago. Discrimination affects depth somewhat on all detectors. Use all metal and you allow the unit to extend to it's maximum depth without regard to internal discretion's.

We are looking for when the nickel and quarter goes beyond 4 out of 5 passes of IDing the coin. 4 out of 5 is OK. 3 hits on a nickel and 2 in Iron means it is loosing it's lock (or it's ability to get a decent conductivity reading).

My F2 locks onto nickels at the same depth as it does a quarter. About 7". My LRP locks onto a quarter until about 9" but the nickel starts getting weak at about 4" max and starts hitting into Iron. If you looked at a horizontal line from 0-99 (Iron to silver), it's almost like the area from 20-60 dips down like a valley. If the machine cannot get a good C reading, it throws it to the next reading it can read (further up or down the scale to whatever is closest, and nickels at 38-39 don't disappear, but gets thrown into Iron since the unit is much more sensitive to IT).

I had the sensitivity at 10, Mode 4, the rest default.

Don't be concerned about the first three modes. They won't follow the depth of the LRPs capabilities as well as 2,3 and 4.

If you get 4 nickel hits and 1 in Iron, that's OK. Keep moving the nickel away until you do a 1,2,3,4,5 in front of the coil and 2 out of 5 are not nickel (watch the numbers). A nickel hits 37-40. If you get a constant 37-40 and all of a sudden the numbers start moving (31, 25, 48, etc.) then the unit is having a difficult time IDing. If it does that 2 out of 5 times, check the distance to the coil from the coin.

Well, Jorge hasn't gotten back to me after I sent him my results Thursday. I played with both my LRP and the QDP today, using the 10" elliptical as well as the 11" DD on the LRP and then performing the test on the QDP with the 10" elliptical as well. What I experienced was that the quarter I had kept showing up at the 10 cent segment, and a dime and zinc penny showed up under "alum". This happened unless the coin was directly next to the coil. I replaced the batteries thinking that they may be weak. But even with new batteries, same results.The funny thing is that the nickel showed up under nickel and locked until about 6-7" away before it starting showing up as foil and iron. Something is just not right. I even moved to a different area thinking something foreign could be affecting the test.

I keep watching detectMO video at the school yard, and he even says that the LRP hits the nickel constant in the beginning, then just starts scattering into iron after a few seconds. It's almost like the magnetic field goes through a fluctuation then calms down then fluctuates again. I don't want to stir up a problem for FTP, but if there is an issue, they should be aware about it ASAP. Or maybe they may think that it's a Bounty Hunter and you get what you pay for.

The unit does detect metal, and at a good depth. But without a more accurate ID, the disc, V-Break and notch are basically useless. And you have to wonder if the GB is not affected as well.

Great observations! LRP is a great little machine. But I did notice the recovery is a little slower than the ETP and its weird with nickels. I'm hoping the new fisher F44 is more along the lines of ETP performance with the LRP features plus Fetone and backlight.

Thanks. You and dirtfishing have the most informative video's on the units you review. I am hoping for the same thing on the F44 as well. I'm sure you'll do an awesome review on it as well.

Hello everyone! I just airtested my lrp, interesting. In regards to nickels I've noticed that while in two tone the id lock seems to correspond to the point the vco starts to crest from one level of loudness to the next. I've tested mine with the stock 11", 8" concentric and a nel sharpshooter. Just a side note the stock coil falses on wet grass and anything it brushes on, not an issue with the nel. If i get a nickle lock while detecting I'm expecting to dig a pull tab. The nickles don't seem to lock in;) I really hope a software or hardware fix is available in the future. Still a fun little machine! Best regards, iqwozpoom

Where did you get the NEL coil? Did you have to order it from the Ukraine?

Thanks for the input.

I got it from one of the US distributors. You might have to wait to have one made if you ordered one, I lucked out and got one of the three of any of their coils in the entire factory with a push pin connection. It would probably be easier to get a standard screw in connector and get a patch cord made.

I wish I had more time to do more frequently. I've been house renovating, selling, and moving the past 6-8 months.

Hi all, this is very positive, thank you all for your your time.

If you are conducting tests, make sure you reset your machine to factory defaults, then modify only the settings you are using for testing.
Do this for every test, in this way we will all use the same settings every time.

At the moment, I am using (and recommend using) DISC4, full sensitivity. No other changes.

We are following this thread and working on replicating this issue for follow up.

Thank you all.

My air test may have been inconclusive...

I am not an air test expert. In my air test recently, I tested my LRP like the person in this video:
video: https://www.youtube.com/watch?v=qNSGFO0DXFI

I was working off of the back side of the coil, and under the impression that the EM field travels equally in both directions.

Today I threw a quarter, a dime, a nickel and a penny in different areas of my thick lawn. This allowed me to ground balance, then raise the coil about 2" and seek out the coins. Once I found each coin, I would raise the coil to see where I lost the signal of the coin. Each coin hit as it should and IDed properly. I could raise the coil 8" or so before I started losing the quarter and the penny. It was around 6" or so that the dime started to disappear. The nickel was 5" or so before I started getting 3-4 out of 5 nickel IDs.

Like I said, I am not a big air test advocate. I hunt and determine my experiences by what I dig, how deep I dig. Like I said in a previous post, I don't want anyone to lose confidence in the LRP over something I may not be doing correctly. That's why I asked others to weigh in.

Once I did a factory default reset, and used the ground balance to determine coins on the ground (not in the air), the LRP seems to be working to it's designed standard. And doing an air test off of the back side of the coil is not going to give as accurate results as working off of the face of the coil on the LRP or the QDP.

No worries Hightone. If there is any type of discrepancy with nickels, I would like to know. This doesn't change my feelings on the machine at all. I would rather be aware of something like this ahead of time, than always wonder while I am hunting. Machines with nuances can sometimes be helpful with identifying trash :)
I am curious on how it identifies the old beaver tabs and the newer tabs in the ground. I like to dig them at my favorite ball field to get them out of the way. This field has been an adult softball field for many years, so I pull lots of beaver tabs from there every year. I hope to set a personal record this year with my 2 FT machines.
