HardPack Posted December 21, 2016 Share Posted December 21, 2016 Operating the Makro Gold Racer with 5.5x10 coil in All Metal Mode, ground balance 60 to 70; sensitivity 60 to 75; threshold 22; isat 6; tracking 0; low tune: freq shift 3; Sun Ray Pro Gold 150 ohm head phones; fully charged batteries; removed & cleaned coil scuff plate. Ground is wet from recent rain, on level and sloped terrain, no water. When running the scoop over the coil without touching the coil (with the detector on the ground or elevated with coil at angle to ground surface) get a rolling chatter in headset, on two occasions the detector shutoff. With the detector setting on the ground and the coil placed flat on the ground surface the chatter stops. Wrapping my hand around the shaft and coil cable lessens the chatter. Same issue with the stock Makro 35 ohm headset. When the head phones are unplugged the rolling chatter stops. No other problems with detecting detects boot tacks, lead shot, small lead fragments or small gold. What is going on, anyone else had this issue and found the fix?

AU_Solitude Posted December 21, 2016 Share Posted December 21, 2016 I think this is a known issue with the headphone socket on some of them, this is why I have passed up purchasing one for the time being. If you unplug your headphones there shouldn't be any issue, unfortunately, most of us use headphones for a reason. Link to comment Share on other sites More sharing options...
HardPack Posted December 21, 2016 Author Share Posted December 21, 2016 Thanks for the info AU. I sent Makro an email, this MGR is approximately 11 months old perhaps they have a fix by now. Link to comment Share on other sites More sharing options...
Steve Herschbach Posted December 21, 2016 Share Posted December 21, 2016 They have a fix for sure because properly operating units do not have that problem. Mine does not. Keep on them until you get it repaired under warranty. Link to comment Share on other sites More sharing options...
HardPack Posted December 21, 2016 Author Share Posted December 21, 2016 I have attempted to contact Makro's online Technical Support Unit but keep getting a " 500-Internal Server Error" and the message fails to transmit. So I just sent Nokta/Makro a PM. See what happens. Link to comment Share on other sites More sharing options...
