Land Ranger Pro & Jumpy Numbers

Hello all. I've been using a Land Ranger pro with the stock 11" DD Coil since June. I am aware that one of the characteristics of this detector is it's not too accurate in the nickle range and will almost give out a jumpy reading in that zone. My detector certainly does that. But it also does this on higher readings. As you know when you first go over a target the first reading you get is usually not too accurate and that you need to zero in on the target doing multiple passes until the numbers basically get more steady to get an idea of it's conductivity.

As for my detector, it's a very often occurrence for the first reading to be vastly different from the later readings. For example; when I go over a target the first reading my say 76 first ---> sweep. Return sweep <----- it would say 43. Second ----> swing it would say 24. Second return <---- sweep it would further drop to 19. Third ----> sweep it would be 16. And Third <----- sweep it would be 14. All subsequent sweeps the target will then read in the iron range. Causing me to reject it and move along. This happens all the time and it make for a rather tiresome hunt as you are stopping all the time to check these potentially good signals that move to iron range after a few additional sweeps. I use all metal mode with sensitivity usually at 8 and only bring it up when I come across a nice sounding target to further check it out. It does this on both my sites.

Would purchasing a quality after market coil like NEL make the reading a little less jumpy and accurate? Thanks.

I don't know. When a signal is high one way and lower the other, it usually means an angled target in the soil. The deeper a target is, the more chance the signal will travel also. The LRP is ID accurate on the high end to about 6", though the lower end (nickels) seems to lose lock on accuracy after about 3-4". Of course, depending on the soil as well.

Has anyone tried different coils such as fisher and teknetics useing the adapter from detectingmo?
i have an adapter coming . still i am wondering about jumpy vdi if this might help?

thanks, jim

It does that in clean ground? If there iron bits it could that it's just sensitve enough and fast enough that it averages until you find a clean sweep angle.

Isn't the coil on the lrp a teknetics greek series dd coil with a different connector ??

I'm planning on buying a lrp but I don't really like the sounds of irregular readings, I might have to reconsider....

The OP had one post. Maybe he had a loose plug, who knows?

I've never experienced the degree of jumpy numbers on a LRP as I did on a few others I owned (CoinGT for one). They all do it to a degree.

I've used the 11"DD and the 10" concentric on my LRP, Some targets calm down with slower shorter swings. If I hold down the MODE button, the LRP is temporarily in All Metal mode with ID, which helps clarify iffy or deeper targets. That's why you need time to learn a detector. Jumpy numbers not an issue for me.

I did buy Craig's converter before Winter.

Well I use All Metal Mode most of the time. The jumpy numbers seem too be most noticeable on nickle signals once you are over 5" deep. The local 10cents register 29 on the VDI. 20 cents here (copper nickle) will come in at 35 on the VDI. However once you get to around 5" mark these numbers would be bouncy. Before that they would be dead one. It's not a big problem as I have been using this machine for 8 months. I know pretty well what I have under the coil before I dig it. A deeper 10 cents will bounce 20-29 but seldom go over 30. A deeper 20 cents will bounce 20-35 but very seldom will go to 36.

Checked multiple times that cable is connected securely and not too much stress on cable angle where it goes into the coil or control box. Coil cable also strapped down to prevent falsing from cable rubbing against the shaft. Simply wanted to know if a change to after market coil will tone down the bouncy VDI reading and error readings where multiple swing on a target that originally read high will drop all the way down to iron after multiple fairly fast swings.

Depending on your soil minerals, yes, 5" could be about right before the signal would travel, especially if you do swing fast. In my mild soil, ID is usually pretty accurate to about 6 or 7 inches. IDs aren't real reliable anyways as many different metal configurations can induce the same ID signal as a coin. A flat coin will not travel (or as much) as a rule, but even that rule isn't always true, even with more expensive machines.

I recieved craigs adapter , and put on the f 44 coil WOW in my soil nickles and zinc hit hard i was getting all the different coins but nickles and zinc were just jumping up and saying here i am. it seemed that the numbers were pretty stable unless you swung it fast or had the sens. to high . it seems to be a very sophicasted machine . i am comparing it to my omega 8000 and i am very happy with the results.
the coil connection on lrp is plug . greek and f series are screw in . with an adapter you can use any of these coils i personally dont care for the 11 dd coil as i like cherry picking the places others fear to tread trashy iron and pull tabs with bottle caps with greeks 5 inch coil
went out today for more testing at a park pavilion full of the above trash still gleaned over 5 dollars where others have been
just keep moderate sens and go slow , numbers are good and not any falsing. in my humble opinion maybe the jumpy vdi may have been the 11dd coil and seeing to much ground at one time. i have had no jumpy numbers with greek coils.
