Choosing the Right STA Device for Your Workflow

The STA range has been designed around a simple idea: capture accurate, reliable field data without slowing operators down. Every device in the range supports weed mapping, tree mapping, spraying, and general GPS field data collection. The difference lies in how each device is optimised for specific workflows, tools, and accuracy requirements.

This guide breaks down the STA Logger, STA Explorer, and STA Explorer HA to help you choose the right device for your work.

STA logger

The proven, versatile original.

The STA Logger is where it all started. It has been around since 2019 and remains a highly capable and adaptable device, particularly for teams that need flexibility across a range of field workflows including weed mapping and spraying.

With a rugged outer shell and a wide ecosystem of accessories, the Logger is built to handle demanding environments. Its slightly larger form factor is rarely an issue in backpack-based workflows, making it especially well suited to backpack spraying and weed mapping programs.

Key specs

• Length: 14.5 cm
• Weight: 248 g
• Battery: ~20 hours continuous use

Key features

• Extremely rugged construction
• Wide range of accessories including 3-way switch attachments, mapping switches, mounts, and spray trigger integrations
• Highly adaptable across workflows

Best suited for

• Weed mapping and spraying programs
• Backpack spraying workflows
• Teams wanting a lower entry price point
• Harsh environments where durability is critical

STA explorer

The new industry standard for weed and tree mapping.

The STA Explorer builds on everything the Logger does, but refines the experience for modern field workflows. It is smaller, lighter, and more integrated. Switches, mounts, and controls are built directly into the device, reducing setup complexity and improving efficiency in the field. USB-C charging modernises the platform, while backwards compatibility ensures existing accessories remain usable.

A key advancement is the integrated movement sensor, which enables automatic detection of planting actions. This makes the Explorer particularly powerful for tree mapping and forestry applications, where reducing manual input improves speed and consistency.

Key specs

• Length: 10.3 cm
• Weight: 147 g
• Battery: ~20 hours continuous use

Key features

• Integrated 3-way switch and side button
• Built-in mounting points
• USB-C charging
• Multi Jet Fusion casing
• Backwards compatible with existing accessories
• Movement sensor for automatic tree mapping and planting detection

Best suited for

• Tree mapping and forestry operations
• Weed mapping with handheld or gun-mounted spraying systems
• High-volume spraying workflows
• Users wanting a lightweight, streamlined device
• Teams focused on efficiency and ease of use

STA explorer HA

High accuracy tree mapping and precision workflows.

The STA Explorer HA is designed for applications where positional accuracy is critical. By incorporating an RTK-capable GNSS chip and external antenna, the Explorer HA enables post-processed workflows that deliver highly precise location data. This makes it ideal for high-accuracy tree mapping, asset mapping, and environmental monitoring, where exact positions are essential. The device is optimised for PPK workflows under low dynamic movement.

Key specs

• Length: 15.9 cm
• Weight: 182 g
• Battery: ~10 hours continuous use

Key features

• RTK GNSS capability
• External antenna for improved signal quality
• Optimised for PPK workflows
• All core Explorer features retained

Best suited for

• High-accuracy tree mapping
• Precision weed mapping and monitoring
• Forestry compliance and reporting
• Workflows where spatial accuracy is critical

Choosing Between Them

All three devices support weed mapping and tree mapping workflows. The right choice depends on your priorities:

• Choose the Logger for rugged, flexible weed mapping and spraying workflows at a lower cost
• Choose the Explorer for streamlined, efficient weed mapping and tree mapping in day-to-day operations
• Choose the Explorer HA for high-accuracy tree mapping and precision-focused projects

The strength of the STA range lies in how well each device aligns with real-world field work. From large-scale weed mapping programs to precision tree mapping and environmental monitoring, each device has been designed to reduce friction in the field while improving data quality.

Choosing the right device ensures more efficient workflows, better spatial data, and greater confidence in your results.
