Nokta IM13 5 inch Waterproof DD Coil for Nokta Impact

The IM13 5" DD coil is compatible exclusively with the Nokta Impact metal detector. This coil will not physically connect to other Nokta models like the Simplex, Anfibio, or Multi-Kruzer. If you own a different Nokta detector, check the metal detector search coils: dd, concentric, monoloop & sef upgrades collection for coils designed for your specific model. The compact 5" design transforms your Impact into a precision instrument for tight spaces and challenging terrain where larger coils struggle.

You will experience a reduction in absolute depth compared to the standard 11" coil, which is typical for any small search coil. However, in trash-heavy environments, your practical depth increases because the smaller footprint prevents valid targets from being masked by adjacent iron trash. The 5" coil excels where precision matters more than maximum depth, particularly in iron-infested areas and spaces where larger coils are impractical.

The IM13 5" coil is fully waterproof and handles saltwater beach hunting without issue. The DD configuration handles saltwater mineralization better than a concentric coil by maintaining stable ground balance in high-conductivity environments. The coil itself is submersible, making it ideal for beach hunting around pier pilings, rocky areas, or crowded swimming zones. You're limited to shallow water detecting where the control box stays above the waterline, but the coil's compact size and waterproof construction make it perfect for working wet sand and surf zones.

The IM13 5" coil ships with a protective coil cover included in the package. The cover protects the coil's bottom surface from abrasion when you're working rocky ground, gravel, or hard-packed sand. It also includes the complete mounting hardware needed to install the coil on your Impact detector, so you don't need to purchase any additional accessories to start using it. Everything you need to begin detecting with the 5" coil arrives in the package.

The IM13 5" coil excels in trashy parks where larger coils get overwhelmed by multiple targets. The coil's enhanced target separation in iron-infested areas helps you isolate individual targets in environments with heavy trash. The compact 5" design provides better target separation than larger coils, allowing you to work effectively in parks with challenging trash profiles. When using the 5" coil in trashy parks, we recommend using the Impact's Di2 (Two Tone) or Deep mode depending on your ground conditions. Keep your swing speed slow and deliberate to allow the compact coil to isolate adjacent targets.

The IM13 5" DD coil handles mineralized soil well thanks to its Double-D configuration, which provides better ground balance stability than concentric coils in high-mineral environments. The DD coil configuration handles mineralized ground better than concentric designs, making it an excellent choice for detecting in areas with challenging soil conditions. While you'll sacrifice some depth compared to the standard 11" coil, you gain the ability to pinpoint targets precisely. If your relic site has moderate trash density and challenging ground, the IM13 is a solid choice for isolating surface targets and working effectively in spaces where larger coils are impractical.

The IM13 5" coil weighs noticeably less than the standard 11" coil, which reduces arm fatigue during extended detecting sessions. The lighter weight makes the Impact feel less nose-heavy when you're working tight spaces or swinging in confined areas around obstacles. For detectorists with shoulder or elbow issues, the weight reduction is meaningful over a 3-4 hour hunt. The difference is most noticeable when you're working vertical surfaces like riverbanks or scanning around pier pilings where you're holding the detector at awkward angles. The reduced size and lighter weight improve maneuverability around obstacles.

The IM13 5" coil is fully compatible with both the standard Nokta Impact and the Impact Pro Pack version. If you own the nokta impact pro pack metal detector – multi-frequency, 12 search modes, the IM13 installs and functions the same way as on the standard Impact. The coil is designed specifically for the Nokta Impact metal detector platform and delivers the same enhanced target separation, improved maneuverability, and superior ground balance performance regardless of which Impact variant you own.

The IM13 5" coil is waterproof and works well for shallow creek and river hunting where you're wading in water. The compact size lets you work between rocks and around submerged logs where a larger coil would snag. The DD coil pattern handles the mineralization in streambeds better than a concentric, maintaining ground balance in iron-rich sediment. The coil is perfect for underwater metal detecting in shallow creeks and rivers where precision matters more than depth, allowing you to pinpoint targets precisely in challenging underwater environments.

The IM13 5" coil does make the Impact lighter and easier to swing for younger detectorists or beginners who find the standard 11" coil tiring. The reduced weight and smaller footprint make the detector more maneuverable, which helps new users develop consistent swing technique without fighting arm fatigue. The tradeoff is depth: beginners hunting open fields or low-trash sites will find more targets with the 11" coil's extra depth. The 5" coil is better suited for teaching target separation skills in trashy environments where the learning curve is about isolating good signals rather than maximizing depth.

The IM13 5" coil includes the complete mounting hardware needed for installation on your Impact detector. The coil ships with everything required to attach it to your detector, so you don't need to purchase any additional accessories to start using it. The included hardware allows you to mount the coil securely to the Impact's lower shaft. Once installed, the compact 5" design transforms your Impact into a precision instrument for tight spaces, giving you better target separation in junky areas and improved maneuverability around obstacles where larger coils struggle.
