Overview
NEL's latest coil, built on more than 10 years of experience in making search coils and designed around what detectorists asked for. Like the best-selling Tornado, it is the "golden mean" across all key characteristics: depth, metal separation, and sensitivity to large and small targets.
It is very light and optimally sized, which makes it versatile in any search conditions. It responds very well to targets from under 1 g to over 10 kg, at depths no stock coil can reach. It is lighter than any stock coil, so you can search all day without fatigue. It comes with a new, improved coil cover with side reinforcements for greater wear resistance. Recommended as a replacement for the stock coil.

Important for Minelab X-Terra
How do I set the ground balance?
Use automatic ground balance. On X-Terra 50, 54, 505, 30, 34 and 305 you can also use manual ground balance. If the detector will not balance, reduce the sensitivity by 50%.
Which Noise Cancel setting should I use?
- Set it to 0 by default.
- For the longest reach on a large copper coin in air, set it to +1. This may cause false signals from the ground.
- To minimise the response to hot rocks or heavily mineralised ground, set it to −1 or −2. Change the value until the detector stops reacting to such ground.
- Where it works best
- All-round searching in any conditions, from small coins to large objects. The low weight and the reinforced cover are made for long trips and daily work in the field. Works well as your main coil instead of the stock one.
- Recommended for
- Beginners and experienced detectorists.
Features
The coil is fully waterproof and submersible. The body is filled with epoxy resin and finished with a black marine-grade coating, the kind used on yachts and boats, so it can be used without a plastic coil cover. It handles medium and high ground mineralization well.

Cable strain relief
Protects the cable from kinking and also provides complete waterproofing.

Robust mounting bracket
Holds the coil firmly on the stem.

Outer shell
Made of impact-resistant, UV-resistant plastic.

Coil cover
Protects the search coil from damage and chipping.

Wear-resistant coating
Made of composite materials, so the coil can safely be used without a cover if required.

Rubber rings
For a firmer fit of the coil on the lower stem.

Connector
Gold- or silver-plated contacts.

High-strength cable
With a larger conductor cross-section. Made in Germany.

Protective cap
Protects the connector from dirt and dust.

Fixing bolt and hook-and-loop strap
Supplied with the coil.
Every NEL coil is field-tested for detection depth before sale.
