It's great to see Nel still around, they've survived the odds so far and now they've released their range of coils for the Legend.  Legend owners now have an additional 10 coil choices for the detector, and this will mean it's fiercely competitive with the best of the best from any brand.  That 17x15" Nel Big would have to add some depth, then the absolute tiny gold nugget (flake) sensitivity of the Nel Snake at 6.5 x 3.5.    The Nel Superfly and Tornado are also coils to take note of.
