    Building your own coils

    I looked high and low but no longer have the coil spec info. Too bad I think I had measured maybe 6 different coils back in the day. The good news is I have the electronic meters (LCR, DMM) and could measure one this weekend. The only Explorer coil I have on hand to measure is the 11" SE Pro...

    Comparison - Manticore vs EQX 800 vs Explorer SE Pro

    Accept for the Kennedy Half, and 1964 quarter and dime these are all dug coins. These results are in air tests, no soil mineralization in play. Soil mineralization will impact the results, to the degree depends on the soil mineralization and condition e.g. bone dry, damp, sopping wet rusty iron...

    Comparison - Manticore vs EQX 800 vs Explorer SE Pro

    I sampled a bunch of targets today with the Manticore and made some observations. I used mostly default settings...All-Terrain, General, Sensitivity 26, Multi IQ, All Metal Observation 1 - The numeric display becomes a jumble of jumping around numbers (useless) well before max detection depth...

    Building your own coils

    Here's a blast from the past, the ABS plastic coil shell thermoforming apparatus. 24" vacuum platen with quartz heaters dual vacuum pumps and two reserve vacuum tanks. Heat the sheet of plastic until is sags them bring it down on the coil shell mold and smash it with vacuum.

    Building your own coils

    A coil can get out of balance when bumped against something if only for a fraction of a second. If bumped hard enough to flex the coil a bit and disturb the balance between TX and RX it will produce a signal in the headphones. But as the coil is encased in epoxy it will flex back, return to its...

    Building your own coils

    @Odanscoils commented that he would like to know how to build a concentric coaxial/coplanar coil for his Minelab Explorer. I'm starting this thread to discuss. If you take an Explorer DD coil apart you will find two windings of copper magnet wire. A thicker heavier gauge wire TX (transmit)...

    First impressions on the Manticore design. I sure will. I have a collection of small gold just for testing.

    ^^^ this was true for many sites I hunted in NY.

    minelabs bad decision on coils

    I think back in the day of Explorer DD coils it was all about achieving more depth in mineralized soil to reopen all the old pounded sites, advantage DD coil. Still true today. Having built both DD and concentric/coplanar coils DD's are just easier and cheaper to build.

    minelabs bad decision on coils

    For picking through rusty nail/trash hell sites what you want to ask Minelab to build you is a concentric, coplanar coil. That coil has a cone shaped detection field, it's like using a 3" coil with the depth of a 9" coil. Not a theory, I built one of these coils for a Minelab Explorer. The...

    Explorer SE 3D Printed onto Equinox Shaft

    Left/rear between the arm cup and the stand. I'm using a lightweight LiPo battery so it's small. So long 8xAA's. Headphone mono jack removed, replaced with the same 5 pin mic jack the coil and X1 probe use. If you look closely at the control box, just above the headphones you can see the toggle...

    Comparison - Manticore vs EQX 800 vs Explorer SE Pro

    Those are from the famous "Potato Patch" mine I visited in my area. That's just what was dug that morning and picked out with a detector from that dark grey dirt pile. Named the Potato Patch because they find nuggets the size of Potatoes.

    Comparison - Manticore vs EQX 800 vs Explorer SE Pro

    @JimmyCT yes I have mind melded with the Explorer at this point. Worst Target Signal Ever? - Saltwater beach on the wet sand. The target crosshair did not move, no target tone, the only indication of a target was the threshold tone went HUMMMMMMMM who would even notice something that slight let...
