A transparent coil bolt… Have you seen such a thing before? After opening the Karma box, I realized that it was the most artsy-fartsy coil I had ever held in my hands.
I wonder why the coil is shown in silhouette on the back wall of the box. I was scared at first as I thought the coil had been imprinted on the box during transport. But I was wrong – with the box everything is OK, it’s simply an unusual decoration.
I opened the box, and… Have you ever seen this before?
The first thing I took out of the box was the transparent bolt. There is a sense that the bolt is made of glass. Looks unusual – I never saw such coil bolts.
The Karma coil… It’s a rare case when you are holding a metal detector coil in your hands, and it’s hard to fault the merest trifle: neither burrs or molding defects. It feels like the coil has been made for an exhibition (although it’s a usual specimen for sale).
Shape: round. Size: 13 inches. Type: DD. There exist some varieties of coils that fall under genre categories: e.g., the ‘Steering Wheel’ coils (Coiltek 15 DD, Detech 16.5 DD Pro). There are also the ‘Buttefly’ coils (Minelab 11 FBS, Detech 13 DD Ultimate). Here there is a category, too: the Karma 13 DD is a ‘Spider’ coil.
And now the most interesting thing begins… The middle positioned cable entry point’s secret has been revealed: when you put the machine flatwise with the coil in a horizontal position, the cable strain relief invariably bumps up against the lower shaft.
Why did I think the strain relief should be positioned just at the bottom? The coil is symmetrical, so it can be attached to the shaft backwards – with the strain relief located at the top. In such a position, the latter won’t hinder the shaft.
That’s what the Karma 13 DD coil is at first sight. I wonder who will purchase this one. Is it possible to turn a blind eye to the strain relief in the middle? Maybe awesome appearance, stability, detection depth matters? Or is it simply the Price that plays a key role?
Karma coil for Nokta Impact:
They say “made in EU”, but do you know if it’s a big brand metal detector / coil company? Good to know their metal detector / coil manufacture credentials.
Looks like a Detech Ultimate coil to me with modified inner design.
The new 13 “DD coil from KARMA (2021) always has the cable outlet in the same place. But who will detect with its horizontal rod? Personally not me. So I find that to have noted this small” defect “if we can call it that, has no incidence while we detect on the ground, the rod being it directed upwards.
