[QUOTE="rc62burke, post: 229004, member: 800"] Sorry But I have to disagree/ clarify some misleading info. The SD series is not extremely loud? the reason I find this misleading is that the SD detectors are notorious for having a poor audio level, requiring a signal booster to get the best results & enable you to hear the small targets. SD 's were not known as sensitive detectors, so you will miss small shallow nuggets! When you refer to noise cancelling characteristics, this needs to be clarified to reduce confusion, a DD coil handle high mineralisation better than a Mono therefore there will be less noise in regard to the audio & this is due to a reduction in ground noise being included in the audio response. There is no adjustment to reduce EMI other than the tune function. Your mono will find you Gold as long as you are not getting overwhelmed by ground noise, if the ground makes the detector moan & groan constantly go for the DD, I use an SD2200d as my main unit & use a 14" NF mono & recently tried a Coiltek older DD 14" which made a big difference in some hot ground. cheers Lee [/QUOTE]
