One of my favorite machines ever as far as features and options goes. So jam packed full of options it makes makes me wonder what sort of craziness Jorge Saad and Yi Yang would have included if they had no limits. V break Adjustable notch width 4 tones Modulated "VCO tone" that adjusts the audio according to how deep or shallow a target is. 11DD coil stock that air test coins to almost a foot. All-Metal Mode with manual ground balancing that has 1000 phase adjustments. Yes...1000! 10 button presses to go up or down a digit. Don't worry...you can hold it down to cycle faster. :) 3 preset modes (Coin - Jewelry - Artifact) 3 custom modes (Disc 1-2-3) Saves settings when detector is turned off/on. CRAZY good for the price. Performance backs up all those options. Running at 7.7khz this is a TRUE "Frat Bros" machine and loves low conductors (silver and copper) just like the Delta/Gamma/Omega from Teknetics. Fast...deep...good separator and unmasker. Options wise...you would need to make a HUGE price jump to get these options in another brand. There are actually NEW releases in 2017 that don't have 1/2 of these options. Bonkers. Check my video review of the Liberator on Youtube. Just search TheHunterGT :)
