    The Nokta Replaceable Scuba Coil in 20 cm (8 inch) is the larger of the two yellow scuba coils for the Nokta PulseDive, Nokta part 17000167. It comes with its coil cover and twists onto the PulseDive control unit in place of the 14 cm (5.5 inch) scuba coil or the pinpointer coil.

    Which detectors the Nokta 8 inch Scuba Coil fits

    Nokta lists the scuba coil for the PulseDive only. Nokta sells the PulseDive as a 2-in-1 set and as a pinpointer only, and fitting a scuba coil in place of the pinpointer coil turns it into a scuba detector.

    When to use the Nokta 8 inch Scuba Coil

    Pick the 8 inch coil when the bottom is open and the aim is to search a wide stretch of sand or gravel on each dive. Around rocks, pilings or a patch strewn with closely spaced junk, the 5.5 inch coil is easier to place and keeps targets apart better.

    A bigger coil also pushes more water as you sweep it, so expect a little more effort. Follow Nokta's coil change steps before every dive: change coils on land only, never underwater, brush any sand off the O-ring, line up the plastic tab with the groove and twist the coil clockwise until it is secure. To take the cover off, hold it at its rear end, not the front, so the coil does not break. Nokta rates the PulseDive IP68, waterproof to 60 m (200 ft). Our metal detector coil guide explains how coil size and type trade coverage for separation.

    Is the Nokta 8-inch scuba coil compatible with the PulseDive pointer mode?

    The Nokta 8-inch scuba coil attaches to the PulseDive scuba detector body and converts the unit from pointer mode to a full-size underwater metal detector. The coil connects via Nokta's replacement system, allowing you to switch between the compact pointer configuration for pinpointing and the 8-inch coil for broader search coverage. Divers working varied terrain often carry both the pointer tip and the 8-inch coil to adapt search strategy during a single dive. The 8-inch coil provides excellent coverage and depth penetration for open-area searches, while pointer mode remains ideal for tight-space target recovery.

    Answered by John W. · May 2026

    How deep can I dive with the 8-inch scuba coil?

    The 8-inch scuba coil is waterproof to 65 feet, matching the depth rating of the PulseDive scuba detector itself. This depth rating is suitable for recreational diving depths in freshwater lakes, rivers, and shallow saltwater sites. The coil housing is designed for repeated submersion in both saltwater and freshwater environments. The waterproof construction handles the demanding conditions of underwater metal detecting, from beach hunting to river detecting and scuba treasure recovery. The protective coil cover included with the unit helps prevent damage from rocks, coral, and underwater debris during dives.

    Answered by John W. · May 2026

    Does the protective coil cover affect detection depth?

    The protective coil cover included with the 8-inch scuba coil is designed to prevent scratches and impacts from rocks, coral, and underwater debris without interfering with detection performance. Most divers leave the cover on for every dive because it protects the coil investment from damage during underwater searches. The cover is particularly useful when detecting in rocky rivers, coral reefs, or areas with sharp underwater hazards. The included protective cover is part of the standard package and helps extend the life of your coil during demanding underwater detecting conditions.

    Answered by Dan P. · May 2026

    Why is the coil bright yellow instead of black?

    The bright yellow housing on the 8-inch scuba coil provides high visibility underwater, especially in murky or low-light conditions common in rivers, lakes, and silty coastal zones. A yellow coil is easier to track during your search pattern and faster to locate if you drop the detector or set it down on the bottom. Black coils blend into dark substrates and shadows, making them harder to see in turbid water. The bright yellow construction ensures you can maintain visual contact with your equipment during underwater searches. For divers working Nokta metal detectors in challenging visibility, yellow is a safety feature.

    Answered by Richard T. · May 2026

    Can I use the 8-inch coil in saltwater without interference?

    The 8-inch scuba coil is designed specifically for underwater metal detecting and handles the demanding conditions of saltwater environments. You can sweep the coil through surf, tide pools, and saltwater wrecks for consistent target detection. The coil performs reliably in high-conductivity saltwater environments, making it a strong choice for beach hunters and wreck divers. The waterproof construction to 65 feet ensures the coil remains sealed during saltwater dives. The design handles both saltwater and freshwater detecting equally well, providing reliable performance across varied underwater environments.

    Answered by Richard T. · May 2026

    How do I attach and remove the 8-inch coil from the PulseDive?

    The 8-inch scuba coil features an easy replacement design that connects to the PulseDive detector body. The coil is designed for field repairs and maintenance, allowing you to swap between the pointer tip and the 8-inch coil as needed. The connection system is built for underwater use and maintains the waterproof seal to 65 feet when properly attached. The replacement design allows divers to carry multiple configurations and adapt their setup based on search conditions. For specific installation guidance, consult the documentation included with your PulseDive detector or contact metal detector technologies resources.

    Answered by Richard T. · May 2026

    What's the detection depth difference between the 8-inch coil and pointer mode?

    The 8-inch coil provides excellent coverage and depth penetration, making it ideal for open-area searches during beach hunting, river detecting, and scuba treasure recovery. The larger 8-inch diameter covers more ground per sweep compared to the compact pointer configuration, allowing faster searching of open areas. The coil strikes the perfect balance between target separation and detection depth for underwater treasure hunting. Many divers use the 8-inch coil for initial search sweeps in open areas and switch to pointer mode for final target recovery in tight spaces. The two configurations complement each other for comprehensive underwater detecting.

    Answered by Dan P. · May 2026

    Does the 8-inch coil work in freshwater rivers and lakes?

    The 8-inch scuba coil performs equally well in freshwater and saltwater environments. The coil is designed specifically for underwater metal detecting and handles the demanding conditions of both freshwater lakes, rivers, and streams as well as saltwater sites. Divers working freshwater sites for lost jewelry, old coins, or prospecting targets benefit from the coil's 65-foot depth rating and wide coverage. The protective cover is especially useful in rocky rivers where the coil contacts boulders and gravel during sweeps. The bright yellow color provides high visibility in murky water conditions, helping you track your search pattern in varied freshwater environments.
