Jeff McClendon Posted January 26, 2019 Share Posted January 26, 2019 So DSMITH, you would probably get better performance from separate coils according to Steve’s post and the info in the links he provided. Personally, I have the stock Minelab concentric 7.5kHz coil and a Mars Sniper DD 18.75 kHz coil because I use my XT50 for fresh and saltwater beach detecting in the Southeastern USA and both coils are waterproof. The Minelab 10X5 18.75 kHz coil is not waterproof. Jeff 1 Link to comment Share on other sites More sharing options...
Steve Herschbach Posted January 26, 2019 Share Posted January 26, 2019 Ah, but frequency matching is not everything. For starters, I suspect the Anfibio has a higher transmit voltage than the X-Terra and that alone could more than offset any performance issues revolving around coil matching. The fact is with Equinox Minelab has as much as admitted this multi coil approach was not the best. My recommendation is never let theory override observed performance in the field. The only way to really know for sure would be a serious set of tests. All we are going by is theory and opinion. 1 Link to comment Share on other sites More sharing options...
