The Four Simplex+ Search Modes and When to Use Each
The Simplex+ gives you four distinct search modes — All Metal, Park, Field, and Beach — each engineered for specific hunting conditions.
All Metal Mode maximizes depth detection without discrimination, making it your best option when you want to recover every signal in low-trash environments.
Park and Field modes apply multi-tone discrimination to help you cut through junk targets.
While Beach Mode tackles the unique conductivity challenges of saltwater and mineralized ground.
All Metal Mode Basics
Among the four search modes on the Simplex+, All Metal Mode operates as the most permissive setting—it detects every conductive target in range without applying any discrimination or tone filtering.
You’re getting raw, unfiltered signal data, which makes this mode essential for accurate target identification during ground evaluation. Every buried object registers, giving you a complete picture of what’s beneath the coil before you commit to digging.
This mode also pairs effectively with deliberate coil selection. The stock 11-inch Double D coil covers ground efficiently while maintaining sensitivity at depths reaching 10–12 inches in normal soil.
Use All Metal Mode when you’re working an unfamiliar site, mapping target-dense areas, or running initial scans where missed signals carry real cost.
Park And Field Modes
Where All Metal Mode gives you unfiltered signal data, Park and Field Modes introduce structured discrimination that filters low-value targets while preserving signals worth digging. These modes give you real operational control over target discrimination without burying you in noise.
Field Mode runs a 2-tone audio split, separating ferrous from non-ferrous targets cleanly. It’s built for open ground with lower trash density, where you need depth and signal clarity over speed.
Park Mode delivers 3-tone separation with faster recovery speed, letting you work high-trash sites without missing adjacent targets. Coil selection matters here — the stock 11-inch DD coil handles separation well across both modes.
Together, these modes let you match your detection strategy to the site’s specific demands rather than forcing a compromise.
Beach Mode Benefits
Beach Mode solves a problem that standard discrimination settings can’t — saltwater conductivity and mineralized sand create ground signals that overwhelm most budget detectors, producing false positives and masking real targets.
The Simplex+ counters saltwater effects through specialized ground filtering and iron notching, letting you hunt wet sand and shallow surf without chasing phantom signals.
You’re not just getting noise reduction. Beach Mode actively separates ferrous junk from worthwhile targets, giving you cleaner reads in environments where other detectors surrender.
The waterproof IP68 housing handles corrosion resistance against prolonged saltwater exposure, protecting internal components during repeated coastal sessions.
Pair that with the 11-inch DD coil‘s ground coverage, and you’re operating with a system engineered specifically to perform where standard modes fail.
Beach Mode isn’t a compromise — it’s a precision tool.
How Deep Does the Nokta Makro Simplex+ Actually Detect?
When you run the Simplex+ in All Metal Mode across normal soil, you can expect detection depths in the 10–12 inch range.
Though mineralization and target size will shift that figure considerably.
You’ll find that adjusting sensitivity across the six available levels lets you fine-tune performance for your specific ground conditions rather than accepting a one-size-fits-all output.
Pairing manual ground balance with frequency shift gives you tighter control over EMI and soil interference, directly preserving the depth potential the detector is capable of delivering.
Real-World Depth Testing
How deep can the Nokta Makro Simplex+ actually reach before it loses a target signal? In All Metal Mode, controlled testing recorded detection depths of 10–12 inches in normal soil conditions. Your results will vary based on target size, soil mineralization, and coil compatibility with your search environment.
The included 11-inch Double D coil drives consistent depth performance while maintaining stable target ID readings across different ground conditions. You’ll notice the machine locks onto targets cleanly rather than producing vague, scattered signals that waste your time.
Park and Field modes sacrifice some raw depth for better target separation in cluttered sites — a deliberate tradeoff that keeps your workflow efficient. Understanding these mode-specific depth differences lets you extract maximum performance from every session.
Soil Conditions Matter
Controlled depth figures only tell part of the story — the ground beneath your feet determines how those numbers hold up in practice. High mineral content loads the soil with conductive particles that mask target signals, forcing the Simplex+ to work harder before a clean tone registers.
Elevated soil acidity accelerates metal corrosion, shrinking a target’s detectable signature over time. Wet, iron-rich clay compounds these effects further.
That’s where the Simplex+’s automatic and manual ground balance options become critical tools rather than optional settings. You’re actively tuning out ground interference, not just hoping the machine handles it.
Adjust ground balance correctly, and you recover much of the depth the soil tries to steal. Ignore it, and you’re leaving targets in the ground.
Sensitivity And Ground Balance
Sensitivity and ground balance don’t operate independently — they pull against each other, and how you balance that tension determines how deep the Simplex+ actually reaches.
In tested soil, All Metal mode hits 10–12 inches. Maximize that range with these calibration tips:
- Run ground balance in auto first, then fine-tune manually on mineralized ground.
- Drop sensitivity one level if you’re getting false signals — stability beats raw power.
- Use frequency shift to eliminate EMI before adjusting sensitivity upward.
- Confirm coil compatibility — the stock 11-inch Double D waterproof coil is optimized for the Simplex+ signal chain.
You control these variables. Chasing maximum sensitivity without addressing ground mineralization costs you depth, not gains it.
Dial both in together, and the machine performs exactly as designed.
Ground Balance, EMI, and Mineralized Soil Performance
When you’re hunting in challenging terrain, the Simplex+’s ground handling capabilities become one of its more critical assets. You can run both automatic and manual ground balance, giving you direct control over how the machine responds to ground mineralization.
Highly mineralized soils often mask targets or generate false signals—manual ground balance lets you dial in precise compensation rather than relying on the detector’s assumptions.
Mineralized ground hides targets. Manual ground balance puts the compensation in your hands, not the detector’s.
The frequency shift function directly counters electromagnetic interference from power lines, nearby detectors, or radio sources. You’re not stuck fighting EMI; you shift frequency and maintain signal integrity.
Beach Mode adds another layer, incorporating iron notching specifically for saltwater and mineralized coastal environments.
Together, these tools give you a capable, adaptable machine that performs reliably across genuinely demanding conditions.
Is the Simplex+ Waterproof Enough for Beach Hunting?

Beach hunting puts equipment through conditions that expose every design weakness—saltwater, submersion, sand intrusion, and constant moisture. The Simplex+ handles these demands through deliberate engineering, giving you genuine confidence in harsh environments.
Its IP68 rating covers submersion to 10 ft / 3 m, which means you’re protected across these real-world scenarios:
- Wading through tidal zones where saltwater corrosion typically degrades unprotected housings
- Submerging the coil while scanning wet sand and surf lines
- Operating through beach sand abrasion during extended low-tide hunts
- Running Beach Mode’s iron notching in heavily mineralized coastal soil
The waterproof 11-inch Double D coil reinforces the entire system’s durability. You’re not gambling on weather resistance—you’re working with a machine built to operate where conditions actively punish weaker detectors.
Audio Alerts, Vibration, and Low-Light Usability
Durability gets you into the field, but signal feedback keeps you finding targets. The Simplex+ delivers multi-tone audio alerts that shift based on your active search mode, giving you immediate target classification without stopping to check the display.
Audio customization lets you suppress low iron tones through the iron volume control, so you’re not chasing junk on every swing. When audio isn’t practical, vibration feedback activates independently, alerting you to targets through feel alone. That matters in loud surf zones or crowded areas.
Low-light sessions stay functional too. Backlit buttons, a display backlight, and a built-in LED flashlight mean you’re not fumbling in the dark between digs. Together, these features keep you operationally sharp regardless of conditions.
Long-Term Ownership: Updates, Durability, and Value

Owning the Simplex+ long-term holds up against scrutiny. You’re investing in a machine built to remain relevant and field-ready.
Four reasons long-term ownership makes sense:
- Firmware updates load via computer, keeping your detector current without replacement costs.
