MANTI-S Lite Handheld NDVI Sensor for Turf & Crop Health | Made in Britain
MANTI-S Lite Handheld NDVI Sensor for Turf & Crop Health | Made in Britain
MANTI-S is an affordable handheld NDVI sensor designed to measure plant health and turf vigour instantly. Developed and manufactured in Britain, it provides a modern alternative to the Trimble Greenseeker for sports turf managers, agronomists and researchers.
Instant plant health insights to guide fertiliser and turf management decisions.
Measure NDVI (plant vigour) in seconds and optimise nitrogen applications across turfgrass, sports fields, and crops.
Key Benefits
- Instant NDVI plant health measurement
- Detect turf stress before it becomes visible
- Optimise nitrogen fertiliser programmes
- Rechargeable via USB-C
- Lightweight handheld device with LCD display
- Works with OSCAR platform for geotagged logging
Build & Enclosure
The MANTI-S Lite features a high-quality 3D-printed engineering polymer enclosure, designed to provide a lightweight and affordable NDVI sensing solution while maintaining robustness for regular field use.
For users requiring enhanced durability and a premium finish, the MANTI-S Pro features a machined metal and reinforced polymer enclosure, designed for intensive professional field operations.

A Modern Alternative to the Greenseeker
The Trimble Greenseeker handheld crop sensor has long been used to measure plant health and NDVI values.
However, many users are now looking for a modern replacement.
MANTI-S was developed as a new generation handheld NDVI device and validated against Greenseeker measurements in turfgrass trials. Independent testing showed near-identical NDVI distributions on healthy turf surfaces.
This makes it a practical alternative for NDVI-based turf and crop monitoring.
Independent Validation
Independent validation with STRI Group turf trials shows that the MANTI-S produces NDVI measurements consistent with Greenseeker across healthy turf conditions, with negligible bias.
In disease-affected turf conditions, MANTI-S tends to report slightly lower NDVI values, providing a more conservative indication of canopy stress.
This makes it particularly useful for early detection of turf disease and stress.
Manage Turf & Crops with Objective Data
NDVI (Normalized Difference Vegetation Index) measures plant vigour by analysing how vegetation reflects red and near-infrared light.
Healthy plants absorb red light and reflect near-infrared light. The difference produces an NDVI value between 0 and 1, indicating vegetation health and density.
With MANTI-S you can:
- Detect turf stress early
- Identify uneven fertiliser response
- Optimise nitrogen applications
- Monitor disease or drought impact
- Track seasonal turf performance
Applications
Sports Turf Management
Monitor turf vigour across:
- Football pitches
- Golf greens & fairways
- Rugby fields
- Training grounds
- Racecourses
Detect stress before visible wear appears and guide fertiliser and irrigation decisions.
Agriculture & Agronomy
Used for:
- Nitrogen management
- Crop health monitoring
- Yield potential estimation
- Disease and pest impact detection
NDVI has been used for decades to guide fertiliser applications and optimise crop performance.
For deeper surface diagnostics and high-resolution multispectral turf analysis, explore the Lightbox (SPROUT Vision) system, which provides advanced imaging and integrates directly with the OSCAR platform.
Turn Measurements Into Data
MANTI-S can be used standalone or connected with OSCAR Lite.
Using OSCAR you can:
- Log NDVI readings
- Geotag measurements
- Track turf performance over time
- Generate spatial maps
Logging can be done directly from the field via WhatsApp interface.

FAQ
What does an NDVI sensor measure?
NDVI sensors measure the difference between red and near-infrared light reflected by vegetation to estimate plant health and biomass.
Can NDVI help manage fertiliser use?
Yes. NDVI measurements are commonly used to guide nitrogen application decisions and optimise fertiliser programs.
Is MANTI-S a Greenseeker replacement?
Yes. MANTI-S was developed as a modern alternative to the Greenseeker handheld NDVI sensor.
Where is MANTI-S manufactured?
MANTI-S sensors are designed and manufactured in Britain.
