    For what this is worth...I only detect on beaches one week per year. This year I took my Equinox 600 and it made me wonder what all the hubbub was about concerning saltwater beaches. It was stable, quiet, and Beach 1 worked like a charm. I didn't do much in Beach 2 but when I did it performed like a champ.

    My understanding is that a magnetometer will detect any ferrous metals. There are stainless alloys both in ferrous and non-ferrous, so not sure every version is detectable with a magnetometer. I'm sure the manufacturer will know though. Large metal items can mask other metal items, so. it's not as easy as you think to distinguish one target from another with a two box, PI, or other types of detectors and large objects. No way I would be hunting an area with old rusty live ordinance, unless you have a death wish. No amount of treasure is worth dying over.

    Cudamark my dad has warned me about UXB's thank you ...the target is either a type 93 steel or its gold my dad says if that device said steel its off limits ..My dad told me he dosn't think theres any type 95s ..all large steel objects are off limits the last 2 found here were both still live one had 100 kilos of TNT dropped in sept 1944 it was under 4 feet of sand made in the usa my dad told me the drag device either failed or it was dropped at tree top level its target was a school building where young japanese were learning how to fly ..I don't think the device will work may dad says if that beach drives vlf crazy with all the black sand which could be off many different elements not only iron .. what i read people use them to locate large pipes would a layer of thick black sand look like a pipe am guessing yes ..And UXB's theres 1000x as many of them to treasures here so u either dig lightly or u QUIT ..I seen what less then a 100 grams of HE can do i just have to look at my dad ..Thank u for the info

    slatebeltdigger so u like the ML 600 ......My dad says u have to drive about a hour to the beach to a real beach 2 or more hours ..My dad said the nearest iron mines are in North eastern New Jersey and he dosn't remember Hot rocks or black sand being a problem near that part of the atlantic ocean so that machine u used should of worked great ..enless the beach is on a lake then it should of worked perfect ..

    You are right, steel(s) are different story. Pure iron is seldom ever seen in every day life, you will find it in chemical lab and some electronic applications. In common life, iron is mainly present in two forms, a casted iron which is rufly a solution of graphite in iron with many other inpurities, some added in purpose, some not. Objects like large pots, owen parts such as grills and doors, are usually made from casted iron. All the rest are warious steels, which is a general term for iron alloys containing warious amonth of cementite (iron carbide). Thousends of steel alloys are known and used. Concerning metal detecting, i would divide steels in three groups: soft or mild steels, hard steels and hardoxide steels and finally, steinless steels or chromium steels.
    Casted iron and soft steels such as nails, nuts, bolts and many every day items with relatively low amounth of cementite are all feromagnetic, they will be find as "ferrous" with VLFs and PIs, they can be readly detected with magnetometer if large enough.
    Hard steels and hardoxide steels, as well as high carbon steels are feromagnetic too. They will be find with magnetometer, the PIs will mostly find them as "nonferrous", the VLFs will most offently give bouncing VDI or nonferrous number, seldom ever a correct ferrous result.
    Steinless steels with high chromium content such as AISI 316 and to some degree AISI 304, as well as chrom-vanadiun steels are bad candidates to look for. They are only weekly feromagnetic, and what is even more problematic, they are rather poor electric conductors compared with other metals. VLFs will fid them with seriously impaired depth, PIs will most likely ignore them all together. Magnetometer would most likely find them, if they are of size of submarine. Small parts would be ignored.

    I owe you a few more anwsers, IMF. First, the hot rocks. I have already talked how some PIs may be set to shade out hot rocks and soft steels such as nails and simmilar. Obviously, this is not the way you would want to look for iron relics. Neither it is the way to search deep large targets, unfortunately. You wold probably want maximum depth from your machine, right? Under such circumstances a large lump of magnetite (or hot rock) is a legite target, it will be reported by the detector, there is no way around that. Yes, you may dig for nothing, you may also dig for nothing if your find turns out to be an old engine radiator or a modern anchor....
    Second, would i invest more money or dig? I would definetly not invest more money over a single case - this turns out to be conterproductive - always. Build your hardware carefoully and grow with it. Would i dig - it depends. I will explain more of this later.
    Third, if you are looking for a buerried or sunken ship made of steel, the magnetometer or more exactly the magnetic gradiometer is your best friend. You can buy something fency and expencieve or opt for a chip DIY kit where the only thing you will need to do is to connect sensors with provided cable and properly align them. You may find such kits if you google for fluxgate sensors, along with extensive tutorials. You may find usefoul to install the two fluxgate sensors on your boat.

    When looking for a big deep target with a PI, first thing you should asses is to find out the signal comes from a deep large target rather than a bunch of small shallow ones. This can be done by using different settings and coils. Somethimes, some small targets should be dug out to properly verify the large and deep one. This is the first information you will get from your PI. Second, you should asses the depth and size of the target. Again, different settings, different coils and in depth knowledge of your machine will be necessary. This is a second information you will get from your PI. The third information you may get from your PI is optional; if you are using something really expencieve or if you have an extra magnetometer with you, you may find out your target is ferrous or non ferrous. This is all you may get from afortable and DIY machines. This is where casual metal detecting and deep seeking differs - you will be forcet to gether the missing info from other (historical) sources. You will not survive long without the proper investigation for every site you decide to research.
    You may invert the time line of events, as i offently do, to make it look more casual, by first detect the desired sits and properly map the deep finds (i use GPS, camera, measuring band, ruller and precision #geological" compass to keep the booklet of "finds") and than investigate each one from other sources such as old writeings, maps, witnesess etc. At the end of the day you will be able to dig only a few of them and the better the information gathered, the less chance to dig for nothing.

    I want to thank you Greenboy for all this info ..I think am going to do the following i will go at night and mark the exact spot somehow it be underwater probably a foot or 2 depending on the tide with a P.I. ..then when its the lowest tide of the year theres a few days each year the next one in November ..i go there and dig with my dad we use a VLF and check every few inches my dad told me they work ok a few inches he thinks in this area and dig and check ..Here the UXB with horns is the most dangerous and thats the one my dad fears he really believes one can be there .. once again thank u for your time your the real deal treasure hunter that knows his devices

    Have a new question does any company make a small hand held scuba waterproof VLF or MVLF detector or do i have to have someone make up something ...When i dig a hole i want to check inside the hole i be underwater less then 5 feet ..Must be able to tell large steel object up to 4 inches away ..ML 600 and fullsize detectors are to large must have 5" coil or smaller .. I will dig by hand if required ..my dad thinks it might be possible he told me with 8" coil 5khz he could find large coin 2 inches deep on a wet beach but on this beach underwater he has no idea ..Some member knows the answer any info will help

    If my clone pulse dive say target and say my vlf unit says no target because its set to blocks out steel targets i have to dig by hand or quit looking those horns could get broken by a shovel . so far all i find is pin pointers which have only 3" range am guessing from what i seen with my clone P.I. ..My be some company could make a MVLF unit like the pulse dive i will look at all the clones maybe theres one already out there . to me what i see on the videos the targets are only 1"to 4" with the pulse dive and here i figure its going to be worthless because the rings and chains are so thin and small i know soon

    I only found the Nokta makro mini hoard waterproof thats the smallest machine no scuba hand models vlf . is this like the simplex just smaller My dad told me it got to be better then a pinpointer ..i have to look at videos ..Yes this is all junk and probably a waste of time .. but it could save a life and they do sell it on amazon probably . You probably saying my dad is cheap well on this beach they take your gear away and put u in jail if they want to because its near there #1 tourist site

    I am very pleased with my Garrett Apex, inexpensive but works well for me. I have 6 or 7 detectors but the Apex does better on the beach for me.

    Jeff thanks for the info but i what something smaller ..the mini hoard has a 6" coil and after watching many videos it might be what i need ..What i seen on fake tube it was being used on salt beach if its like its older brother the simplex i want it .. My dad says it looked like the best thing he's seen in detectors in 20 years to me this sounds crazy . My dad said if it only had a 4" coil and multi fqz with optional 10" coil in color black he buy 10 of them . He told me he was going to try his hardest to get the real deal ASP ..The clone might be better but ive haven't seen one yet . China makes the best cellphones and soon the best detectors my dad only likes Fisher and Turkey made devices .the Apex is probably a good machine i wish u all the luck with it Jeff

    In reality. The Apex can't even come close on a salt beach to a 600 or 800 Equinox.
