    Planning : New Drag Coil

    I was thinking on building a new drag coil . Either 1.8 M or 2.4 x 2.4 Meter size ..Having problems with trash , magnetite , hot rocks . I don't want to detect small targets good or bad ones . Looking for targets bigger then 25 mm in diameter . the 2.4 size is hard for me to transport were am at . What size would members recommend ? If bigger just say it . Any ideas are welcomed . Remember depth doesn't matter .

    Curious to see if you get a good answer. I have wanted to make my own large coil rig for some time and was surprised that I couldnt find a kit or a circuit diagram to build my own. Do you have a control box and want to make the coil or are you looking for a complete unit?

    My family has a 1M x 1M coil sled they listen to some florida fisher model guy here they should of listen to Greenboy or Carl what i hear they know all the answers . Am just going to have my worker make the coil he says he can if i find out the size i want i'll post more info once he builds it . He told me so far depending on the size 16 AWG - 14 AWG wire 0.6 ohms 300 henry the unit some cheap model . My worker told me 1500 piso to 2000 piso for the parts . After watching this meteorite men am having second thoughts , i think for meteorites a drag magnet is better so if i can afford both i want both . I never thought they be on the surface and be worth 1000 piso a gram am looking for the wrong metal . My problem were am at is iron every where so is nickel and 1/5 of the rocks are magnetic .

    This price for meteorites is 1/3 the price of Gold and more then silver ? Where am at a place called Bicol is famous for meteorites my US family tells me that meteorites are more common here where am at . I have a few new questions the place am at is only 25,000,000 years old and the US is 40x that old . Here the terrain much more steeper then any where there plus it rains 2-5x as much . How are these meteorites on or close to the surface ? One only finds the debri from the explosion or impact that y its on the surface ? Or these meteorites are all less then a few thousand years old ? In august there was a shower of 60 a hour but none reached the ground . How does one know if there in a good area in know watch Meteorite men i better off asking Jeff Williams and slim joke

    What detector are you using? I assume you are using a pulse induction. I don't think vlf would be easy to build or use. Are you planning on building the coil wiring or just adding some fabric to an existing coil?

    I'll leave it to you to figure out where the opposite goes.

    If your heart is in it you will find a thousand ways to achieve your goal.
    If your heart is not in it you will find a thousand excuses.

    Ouija Board and map dowsing , one and the same. Just tape a map onto the Ouija Board and you have map dowsing.
    Works great if you like wild goose chases and snipe hunts!

    May you never take one single breath for granted.

    My biggest coil is 2m x 2m but it is very cumbersome and not realy usefoul on my home terrain. I am using it mainly for "exhibition" purposes, to show my rig is really able to find large tarbget on 8m in a test hill. For ignoring small items (a must) i am using DBP2010 with 1m x 1.2m set up to ignore anythig smaller than a beer can. This shortens the depth from normal 4m max to 2m only. another PI is Miner4, which uses mathematical alghorithms to exclude small items, i am using 70cm round coil, dough it works with 50cm coil too. The depth is unaffected, the 70cm setup will give some 2.5 to 3m max depth.

    Greenboy thanks so much for this info ....what u describe is perfect for relic beach hunting i guess the unit my family used which is the wrong one for this . Relic or gold fist size or bigger no trash targets but meteorites are coin size up and what i see up to 0.3 M depth like coins . So maybe there sled 1 M x 1 M is good for meteorites . I need one of the 2 units u mention with a new 1.8 M round coil . My worker was going to use a pulse dive unit which cost very little and seems to work ok on relics that he tested depth wise all i need is 0.75 meters on the wet beach . It reached 0.35 meters on a 350 kilo deactivated uxb with a 140mm coil . Thanks again Greenboy

    After a long talk with my technician about what Greenboy said he told me 1.45 M diameter should be right for relics and large meteorites . for small meteorites he told me with 1mm wire he could build a 0.6 M diameter coil . Hope to start work soon on building both of these coils will post the test results
