You will need to build a skid-plate for mounting, these coils "must" be made rigid to operate. Configuration can be, round mono, oval, rectangular, or even a figure 8 — anti-interference. Each shape has its own benefits depending on your goals. (other variations may work, but experimentation is  required)

To streamline our workflow, we are only advertising the 45" on the site.

We can make these coils from 35" up to 200" in 5" increments. If you require a specific size for a specific application, you can request a price list from us. 

Each size is: "as if configured as a round mono". 

If you were to order a 200" coil, it would have a total circumference of a massive 1596cm.

As these are customs built to order, the exact circumference can vary slightly, but we look to make the size ordered, a minimum circumference. 

(45" = 114.3cm, * 3.141 = 359cm, so the coil would be this circumference.)

All orders of drag coils will have a lead time of at least two weeks, but, the 45" will be the quickest to produce of the lot, as it's the most common and preferred size. 

The cable from the detector to the edge will be 1.5m as a minimum up to 2m, as a maximum. This is due to manufacture steps and suppliers. Expect the minimum, and if you need drastically more, we can provide extension adaptions.
