High Quality Training

Quick & Reliable Evaluation

Visualization and Signature Technology (VAST) is a handheld detector training system that increases trainer efficiency while reducing the training burden. VAST provides visual feedback on the key elements of handheld detector swing technique including the swing speed, swing path and coverage, and the detector search head height and angle relative to the ground. The visual display allows for a detailed analysis of a detector operator’s performance that can be used to enhance instruction and after-action review.

              and a tablet

How It Works

VAST Training provides visual feedback on detector swing by tracking the 3D position, speed and tilt angle of a detector search head. The system includes a small transmitter module that is attached to the shaft of any handheld detector and contains ultrasonic transmitters, an ultrasonic height sensor and a miniature inertial measurement unit. The transmitter emits ultrasonic pulses and communicates wirelessly with two tracking belts that contain ultrasonic receivers, which are placed on the edges of the training lane. The belts communicate over Bluetooth with an Android tablet that processes and visualizes detector trajectory information to the trainer.

1. Visualize Errors

The system paints the area covered by the search head and plots markers if the operator exceeds acceptable parameters for detector height, speed and tilt angle.

				errors that are detected using VAST. Examples include gapping, sweeping too fast and height violations.

2. Archive Training Data

The VAST application allows users to add trainees and link visual feedback to a specific trainee for archival purposes.

3. Expert Templates For Instruction

Create and save templates of expert sweep search technique to use as visual aids to teach correct technique to novice operators.

4. Portable

VAST Training fits in a single handheld military case and can be packed/unpacked in a few minutes.

5. Battery Powered

Each system component, excluding the tablet, is powered using disposable AA batteries.

Frequently Asked Questions

Is the U.S. Department of Defense involved in the development of VAST Training?
Yes, VAST Training is a joint R&D effort between Red Lotus Technologies and the U.S. Army Research Laboratory.

Does VAST Training track the detector search head?
Yes, it tracks the position of the detector search head.

Can VAST Training be used indoors?
Yes, the system can be used both indoors and outdoors.

Can one Android tablet monitor feedback from multiple systems?
Currently, the VAST Training Android application can only display feedback from a single VAST Training system.

Can VAST Training track more than one detector on a training lane?
The current version only supports one detector per training lane.

Can I use VAST Training with a tablet that I already own?
VAST is optimized for the tablet device included with the system. However, for sufficiently large orders, we can port the Android application to an Android tablet model of the customer's choosing (e.g. "ruggedized" Android tablet). Please contact us for further details.

What is the Android tablet that is included with the system?
We include a commercial off-the-shelf tablet with each VAST Training system. Therefore, the exact model included in an order will depend on the product release cycles of the major Android tablet manufacturers.
