Caliber 3.0
Precision Injection for the Water’s Edge.
Caliber 3.0 is Riparian’s precision treatment vessel, engineered to deliver aquatic herbicide and algaecide with exceptional accuracy in environments where traditional spray methods struggle. Built on a shore-launchable, low-draft platform and controlled through advanced autopilot navigation, Caliber minimizes boat drift and ensures treatments are applied exactly where they are intended—no more, no less.
With a documented GPS spray path and safe, remote operation from shore, Caliber supports operators who need consistent, defensible, and repeatable results in waterways where precision is essential.
The Right Dose, Delivered with Caliber.
Engineered for Targeted Aquatic Treatment
-
Autopilot-assisted guidance reduces drift for higher application accuracy
-
Documented GPS spray path supports regulatory compliance and reporting
-
Minimal disturbance to water and surrounding vegetation
-
Operates from shore, keeping crews out of unstable or hazardous water
-
Navigates safely in shallow, narrow, or obstructed waterways
-
Supports vegetation management programs with reliable, repeatable treatment results
Optimized for Key Vegetation Challenges
Caliber 3.0 is purpose-built to apply treatments for:
-
Weeds
-
Algae
-
Floating vegetation
-
Emergent vegetation
Its precision and repeatability make it an ideal solution for treatment programs requiring accuracy, proof-of-application, and minimal environmental impact.
Documented, Defensible Application
Every treatment run can be recorded as a GPS-referenced spray path, providing:
-
A verifiable record of where treatments were applied
-
Clear documentation for regulatory agencies
-
Added confidence for stakeholders and environmental partners
-
Repeatable routes for follow-up or maintenance treatments
This level of transparency and consistency strengthens compliance, improves communication, and supports long-term aquatic management strategies.
