Can you believe that a 13-inch coil for the Minelab X-Terra can weigh less than an original 10.5-inch one? See the photo: weight of the new MarsMD Discovery coil.
Mars Discovery for Minelab X-Terra (dual frequency coil)
Mars Discovery for Minelab X-Terra. Weight: 538 grams. Note: the coil can operate at two frequencies – 7.5 kHz and 18.75 kHz.
This is an original Minelab X-Terra 705 coil on the scales – Minelab X-TERRA 10.5 DD. Weight: 573 grams. The coil has a smaller size (10.5 inches versus 13 inches) and is 35 grams heavier.
The coil has been weighed with a cover. I take it ‘as is’. If the coil has a cover and I’m hunting with it – so it should be weighed with this one. If the coil has no cover – so it should be weighed alone.
Separate weight of the Minelab X-TERRA 10.5 DD coil cover: 69 grams (it is good weight; a perfect cover weighs up to 50 grams, a heavy one is up to 100 grams).
Mars Discovery for Garrett AT PRO
The same Mars Discovery coil for Garrett AT PRO metal detector. Weight: 522 grams. The original Garrett AT PRO coil – Garrett 8.5×11 PROformance DD. Weight: 506 grams. Both have been weighed without covers.
Mars Discovery for Garrett ACE 150-250-350-Euro
Mars Discovery for Garrett ACE. Weight: 535 grams. Comparison with the original Garrett ACE 250 coil – Garrett 6.5×9 PROformance. Weight: 448 grams. Both weighed without covers.
The distinction is 87 grams. But if you look at the difference in coil size – 9 inches versus 13 inches – the distinction is minimal.
I’ve paid attention that Mars Discovery coils come with another bolt. Its separate weight: 10 grams.
