Independently researched Detector Comparison
X-Terra Pro vs Simplex Ultra
Both are light, rechargeable and waterproof to 5 m, but neither is simultaneous multi-frequency. X-Terra Pro offers selectable frequencies; Simplex Ultra offers a more feature-rich 15 kHz interface and carbon-fiber shaft.
Bottom line
X-Terra Pro for frequency flexibility; Simplex Ultra for features per dollar
Choose X-Terra Pro if manually selecting 5, 8, 10 or 15 kHz across park, field and beach modes matters. Choose Simplex Ultra if a fixed 15 kHz platform with recovery-speed adjustment, tone controls, Bluetooth and a fully carbon-fiber shaft better fits your budget.

Specific recommendations
Choose the control system that fits your sites
Minelab X-Terra Pro
Selectable single frequencies help tailor response, although only one runs at a time.
- 5/8/10/15 kHz choices
- Six mode profiles
- 5 m waterproof
Nokta Simplex Ultra
A light 15 kHz detector with extensive tone and recovery controls.
- 1.2 kg carbon-fiber build
- Six search modes
- Firmware updatable
Minelab X-Terra Elite
Buyers prioritizing wet salt stability should price the Multi-IQ Elite before choosing either single-frequency model.
- Simultaneous multi-frequency
- 5 m waterproof
- Iron Bias control
Analysis
What actually changes the buying decision
Selectable frequency is not simultaneous multi-frequency. X-Terra Pro lets the operator choose one frequency; it does not process several frequencies together like X-Terra Elite. That distinction matters most in changing ground and conductive wet salt.
Simplex Ultra’s strength is the amount of adjustment Nokta provides at an entry-level price: recovery speed, tone break, tone frequency and tone volume. Those controls are valuable only if the user learns them.
Both housings are waterproof to the same published depth. Coil options, headphone package, ergonomics and local service should break a close tie.
Reasons to choose this route
- Both offer unusually strong waterproofing for the class
- Both are rechargeable and updateable
- Both provide room to learn beyond preset operation
Reasons to choose something else
- Neither is simultaneous multi-frequency
- X-Terra Pro bundle contents vary
- Simplex Ultra remains locked to 15 kHz
FAQ
Questions before buying
Are X-Terra Pro and Simplex Ultra multi-frequency?
No. X-Terra Pro lets you select one of several frequencies; Simplex Ultra runs at 15 kHz. Neither processes multiple frequencies simultaneously.
Which is better for wet salt sand?
Neither has the inherent SMF advantage. X-Terra Pro offers a dedicated 8 kHz Beach setting, but frequent wet-salt users should compare X-Terra Elite or another SMF model.
Which detector is lighter?
Nokta lists Simplex Ultra at 1.2 kg (2.6 lb), slightly lighter than X-Terra Pro at roughly 1.3 kg (2.9 lb).
Are both fully waterproof?
Yes. Both manufacturers rate these control systems to 5 m (16 ft), subject to correct seals and compatible accessories.
Which has the better shaft?
Simplex Ultra includes a fully carbon-fiber shaft. X-Terra Pro uses a lightweight collapsible shaft but not the same full-carbon specification.
Why choose X-Terra Pro?
Choose it for selectable 5, 8, 10 and 15 kHz operation and the Minelab coil/audio ecosystem.
Why choose Simplex Ultra?
Choose it for low weight, carbon-fiber construction and extensive tone and recovery controls at an entry-level price.
