Enabling the acquisition of high-resolution, precision, flat-field images at speeds of up to 5 knots, Hunter is suited to a variety of pipeline, survey and search applications. Purpose-built for automated operation, the advanced system delivers ease of integration for AUV manufacturers and one-off builders. Manual intervention is significantly reduced through independent control modes, intelligent image collection and automated image and data checking. Automation is supported by range-based focus control; sensor inputs; external autonomous control and autonomous mode selection, along with real-time laser and image quality assessment.

Scout is a fully synchronised system delivering precision still imaging, laser profiling and video. With a specification list matching that of the Hunter AUV system, it also offers the additional functionality of a forward-looking video camera with lighting. This operates independently of the stills and laser cameras through time synchronisation. Producing high-quality video without the need to ‘stop and look’, inspection time is considerably reduced. To provide extra flexibility, Scout can be supplied on a frame or integrated directly into the vehicle.

Pathfinder is a fully integrated, laser and imaging system with co-registered laser, stills and video. Consisting of two Scout stills and laser configurations on a large work class frame, alongside a single video camera, the system is designed to enable slower, large vehicles to collect dense dual data sets with millimetre precision. To offset the reduction in speed when compared with lighter observation class ROVs, this system gathers twice the density of data in each single transit. Featuring forward-looking synchronised video for when high-speed piloting is possible, Pathfinder can achieve double-swath data collection at speeds of up to 5 knots.

PROWLER I: Designed for sled and towed vehicles, Prowler I is a drop camera imaging system for use in environmental, habitat and species mapping surveys when extremely detailed seabed images and mosaics are required.This high-resolution still imaging system can deliver resolving powers greater than 0.4 millimetres at 2 metre ranges and includes optional HD video output. Featuring integrated, automatic laser range calculation with precision calibration, Prowler I enables the shape and size of underwater life and debris to be assessed easily and objectively. PROWLER II: As with Prowler I, Prowler II is developed for use with sled and towed vehicles in the acquisition of highly detailed seabed images and mosaics. Unlike its counterpart, however, Prowler II incorporates dual-mode laser and still imaging capabilities from a single camera and does not offer video functionality.
