"From tests carried out on a variety of soils, the coils have extremely good depth and sensitivity - 80% of the time the finds made were still in the hole and not in the flap even though the loud signals had me thinking they were shallow. Signals on small coins penny sized were good and loud to four inches with bigger coins giving good signals deeper than that. The small coil on the X-Terra 30 is uncanny, great on the X-50 & X-70 too…simply amazing performance!"
"On lawns and for small jewelry recoveries, this coil will work very well and scrubbing along the surface is recommended to achieve maximum detection depths. Similarly, in farm fields, particularly in tight areas between rows of cut crops this coil is very effective as it’s easy to zip along the bottom and detect the sides of the furrows as well. Woodland is another area where this coil offers great potential as its small size gets it much closer to rocks and tree trunks that a bigger coil would not allow"
"This coil is sensitive and has a sharper detection point than most other coils so you will find coins, even some ridiculously easy targets previously missed by other detectors.".
"I am very happy with the X-Terra’s small DD High Frequency coil. It actually exceeded my expectations! The coil was salt water tested: wet sand tested, fresh water tested and was used extensively in a fresh water stream. During the beach tested it was found to be very solid in its performance. It was operated in and out of the water – in both Discrimination and in the All Metal mode. Either way, the coil was flawless."
"Absolutely SUPER on fine gold – this coil’s sensitivity to small gold is fantastic! It’s a great Prospecting coil!"
