GPZ 7000

Our GPZ 7000 upgrades are designed to maximize your detector’s performance seamlessly. By upgrading key components on the motherboard and eliminating noise from critical circuitry, we deliver improved sensitivity and depth. These internal enhancements operate automatically, so there are no extra controls to manage. You’ll experience a smoother, quieter machine with superior depth and sensitivity, without any additional complexity.

GPX 6000

Our GPX 6000 upgrades are crafted to optimize your detector’s performance. By internally upgrading components and reducing noise, we transform the notoriously noisy GPX 6000 into a quieter, smoother-operating machine. With no extra controls to manage, you can enjoy enhanced depth and sensitivity without any added complexity, ensuring a more efficient and effective detecting experience.

GPX Series

• GPX 4000
• GPX 4500
• GPX 4800
• GPX 5000

Our new multi-module input stage reduces noise in the most critical part of the detector by 75% at a minimum.

The Updated Frequency control allows for two hundred and fifty-five positions, providing a 25% swing to pulse width. Perfect for optimising your detector for any aftermarket coil.

Tests have shown that these new upgrades beat the SDC detectors on small gold at depth and will easily compete with the new GPZ-series detector on both small and large gold.

While we priorise our Frequency control and new input stage, our front-end gain control is also available for those dealing with disasterous ground, and coils that require extra control.

GP Series

• GP extreme
• GP 3000
• GP 3500

Our 5th Gen Front-End variable gain control allows for optimal signal to noise management, significantly improving sensitivity and depth capabilities.

Now with a fully variable frequency control—similar to the GPX series—you can optimise for a much wider range of target sizes.

The Latest GP series upgrades will have your machine handling any ground type with ease. (Optional Sensitive-Boost switch for advanced users)

SD 2000

A low-frequency super-deep modification allows you to use the largest coils for the most depth possible, with the ability to switch back to regular operation. (This is only available for the SD 2000)

Gain control will tune your detectors signal amplification to best suit your situation. Small Gold modifications are possible for the SD 2000 upon request, as are audio manipulations for advanced users.

SD 2100 Series

• SD 2100
• SD 2100e
• SD2100v2

We add three timing positions allowing these detectors to be optimised for various sized targets and coils. Added audio frequency boosting gives a sharper response to the detection of gold. A switch is added to allow 3 or 4 pulses, which can improve the detector's ability to deal with tricky ground. Variable gain adds another layer of control to the machine's capabilities in the field.

SD 2200 Series

• SD 2200d
• SD2200v2

We add three timing positions to allow the detector to optimise for various sized gold and a range of coils. A switch gives you three ground mineral timings to best suit the ground you are detecting on, and our new Variable Front End Gain allows you to tune your machine to have the best performance possible regardless of conditions.
