The INV28 coil measures 11 inches by 7 inches in an elliptical footprint, or 28 centimeters by 18 centimeters in metric units. The coil's elliptical shape provides wider ground coverage than round coils of similar length while maintaining maneuverability in tight spaces like between fence posts or under playground equipment. The Double-D configuration enhances target separation in trashy areas and improves ground-noise cancellation in mineralized soil. Weight specifications are not published by Nokta. The included coil cover and mounting hardware ship with every unit.
