Hi in my opinion the SEF 15 X 12 coil gives you much better ground coverage
and a small increase in depth ..if your using the minelab pro coil, if your using the original stock coil then you will get better depth.
Mainly because you can run the explorer with vastly increased sensitivity with out causing overload or distortion.
I personally swear by it.
The etrack has a slightly faster response time and a few extras which you may find
an improvement...i think there is little difference in the SEF and the minelab Pro coils. and finally some peeps find that the SEF coil a little heavy for them ?
I do not agree with this it mainly depends on how you set up the bottom shaft on the machine it is posible to get great balance if you set the length just right for YOU
and adjust your grip and detecting sweep accordingly.
I am 65 years old and have no problems still detecting for 8 hours a day plus on a good site lol.
One further advantage of the SEF coil in combo with the explorer is that you can run maximum sens. on wet salt beaches black sand or otherwise.
Just remember to clean out coil cover after each trip cos running at max. sens will cause problems at the next site you go to.
Best regards and HH PaulB.
