The company’s marketing often highlights “new designs,” “software refinements,” and “improved depth,” but the actual detection range, signal processing, and core electronics are nearly identical. The only true change lies in the battery configuration.

1. Introduction

The Lorenz Deepmax series is widely known among treasure hunters and professional detectorists for its high prices and promises of superior depth. Yet, experienced users have noticed that every new “model” released appears to recycle the same internal technology under a new name.

This post exposes the truth — comparing the Z1, Z2, and Z2 2025 models side by side — to show how the marketing does not match reality.

 2. Core Technology – Identical Pulse Induction System

All three models — Z1, Z2, and Z2 (2025) — use the same Pulse Induction (PI) detection principle. This means one coil acts as both the transmitter and receiver, producing short bursts of electromagnetic fields to detect metal objects deep underground.

Lorenz’s Pulse Ground Balancing System (GBS) was introduced in the Z1 and has remained virtually unchanged since. Each device promises “Advanced Power Pulse Technology” and “PST (Pulse Shaping Technology),” but there’s no measurable evidence of improvement in depth or stability between the models. In real-world tests, all three detectors reach nearly identical detection ranges — typically 4 meters for large ferrous targets using frame coils.

 3. Design and Build – Cosmetic and Minor Hardware Tweaks

Lorenz advertises the Z2 and Z2 2025 as having a “new compact and rugged design” with a “single-piece anodized aluminum housing.” In truth, this is mostly a cosmetic redesign. Internally, the control boards, analog-to-digital converters, and filters operate at the same performance levels as the older Z1.

The Z2 2025 “upgrade” includes only a new display and minor software tweaks — nothing that affects performance or range.

 4. Battery Systems – The Only Real Difference

Here lies the only genuine difference across the three models. The Z1 and Z2 use detachable NiMH battery packs, while the Z2 2025 moves to an external battery box mounted below the housing.

Despite marketing claims of “improved efficiency,” the underlying voltage and capacity are the same. Users expecting higher depth or sensitivity will be disappointed — battery configuration does not alter the transmitting pulse energy or receiver sensitivity. It simply changes how the power is delivered and how convenient the replacement process is.

 5. Detection Range Comparison

Detection Range Comparison

Target Type | Z1 Depth | Z2 Depth | Z2 (2025) Depth
--------------------------------------------------------------
Small Coin | 40 cm | 40 cm | 40 cm
Medium Object | 1.2 m | 1.2 m | 1.2 m
Large Iron Box | 3.0–4.0 m | 3.0–4.0 m | 3.0–4.0 m

As shown above, all three detectors provide identical performance levels when used with equivalent coils. Despite claims of “enhanced sensitivity” or “new electronics,” real-world depth results confirm that these models perform the same.

 6. Marketing Claims vs. Reality

Lorenz claims the Z2 2025 model includes:

• Advanced power pulse technology

• Multi-channel data logger function

• Improved electromagnetic noise cancellation

• New display and software refinements

However, nearly all of these features already existed in the Z1 and Z2. The so-called “new” improvements are simply firmware repackaging with interface adjustments. No measurable data supports increased detection range or sensitivity.

 7. Coil Compatibility and Reuse

One subtle proof that all three models share identical architecture is coil interchangeability. Lorenz states that coils from older Z2 units work perfectly with the Z2 2025, and even with the Z1 in many cases.

This would not be possible if the electronics were truly redesigned. In other words, the detectors all transmit and receive on the same frequency parameters, confirming they are functionally identical.

 8. The Software “Upgrade” Myth

Lorenz warns that software from older Z2 units should not be used on the 2025 model because “it will result in operation failure.” This sounds like a technical advancement, but in practice, it’s a version lock to prevent users from realizing that the software differences are cosmetic — limited to display layout and menu naming. No improvement exists in the ground balance algorithm or pulse control.

 9. Summary and Conclusion

After reviewing the Z1, Z2, and Z2 (2025), it’s evident that these models are nearly identical. Their pulse engine, detection depth, and data logging functions have not changed in years. The only meaningful change lies in the battery configuration and minor display refresh.

While the Lorenz Deepmax detectors are technically capable and well-built, the company’s habit of rebranding identical hardware as “new models” misleads consumers.

If you already own a Z1 or Z2, upgrading to the Z2 2025 will offer no real-world performance improvement. Potential buyers should be cautious of marketing claims suggesting “new depth performance” or “greatly improved range.” Always compare real field results, not brochure statements.

Lorenz has a strong reputation for build quality — but in this case, the “new model” story is simply not true.
