LONG RANGE LOCATORS https://www.omnitron.us/apps/photos/ LONG RANGE LOCATORS LRL'S A few of the MFD, LRL & Directional Locators I have field tested , DB tested, and compared.over the years https://www.omnitron.us/apps/photos/photo?photoID=168089776 168089776 First fully Electronic MFD-LRL, 1979 You placed the antenna housing about 10 inches in the ground and slowly rotated it. until it aligned with the direction of an unknown discriminated target, then the meter peaked, the audio sounded, and the oscilloscope displayed a jagged Signal Line. It weighed a bit over 100 lbs. with the batteries. https://www.omnitron.us/apps/photos/photo?photoID=168089949 168089949 A more advanced fully Electronic MFD, LRL, 1980 Weighing 70 lbs. it was still heavy to tote around, and impractical for some terrains, but it worked great, and several small Treasures were found with it. https://www.omnitron.us/apps/photos/photo?photoID=168089950 168089950 Fully Electronic LRL A Whites metal detector modified into a functional fully electronic LRL. https://www.omnitron.us/apps/photos/photo?photoID=168270513 168270513 Fully electronic LRL MINEORO: Beeps when aimed at Gold. https://www.omnitron.us/apps/photos/photo?photoID=169831744 169831744
