Console display for sprayer station
Spectrum Technologies now offers an after-market display unit that connects easily to existing WatchDog Sprayer Stations. It is particularly suited to sprayer rigs that do not have in-cab computer systems or other monitoring devices.


The new display enables users to view and track wind speeds and direction, air temperature, humidity, dew point and barometric pressure, while on the go, using the WatchDog Sprayer Station. Weather data can be collected and downloaded to a personal computer with Console Sync
software, which is also included.

The Sprayer Station handles adverse conditions with a UV stabilized, compact housing that is waterproof and  resistant to chemicals. Reliability is enhanced by eliminating moving parts, replacing wind vane and cups with ultrasonic transducers.

Improving control of application
Ag Leader Technology is adding new features to its DirectCommand application control system. The system now interfaces to the Raven Sidekick chemical injection pump for control of chemical injection applications. The InSight display and CAN module replace the Sidekick console, directly connecting to the injection pump. Automated prime and
calibration routines, as well as advanced sensor diagnostics are part of the new direct injection module’s functionality. It can be used for herbicide, fungicide and insecticide applications, along with N-Serve injection applications.

DirectCommand now comes with three channels of
granular product control within the spreader module,
providing operators the capacity to apply as many as three products simultaneously at varying rates. DirectCommand simplifies spreader control by controlling the conveyor and spinner speed, along with monitoring bin levels. The system reads ground speed and automatically adjusts product flow to match target application rates. The spreader control system supports PWM, motorized servo, Mark IV.2, Mark IV.4 and Mark V hydraulic control values.

Precision guidance with added touchscreen
Hemisphere GPS recently introduced its Outback S3 system, the next generation in Outback Guidance products. It combines the most popular features of the Outback S2 and the Outback 360 with the latest developments in Crescent GPS receiver technology, and has a large colour touchscreen for constant situational awareness.

The Outback S3’s 8.4in, high resolution touchscreen displays clear and easy-to-read data in real-time. There is a variety of basic guidance patterns with the ability to set
multiple guidance lines and return points in a single task. The electronically integrated Outback Steering Guide uses GPS data and specific job details to display simple heading direction and provide precision guidance. It can also set perimeters, drop flag markers, create job templates and record job specifics such as the type of crop, wind direction and temperature. Such data can then be transferred to Field Notes personal computer software via a USB thumb drive to
generate maps and reports.

Although Outback S3 is loaded with features and the latest technology, it is reported to be extremely user friendly.

The Outback S3 is also expandable to work with a variety of other Outback Guidance products and accessories. Outback eDrive TC GPS assisted steering system extends the functionality of the Outback S3 by utilizing GPS technology to aid in more uniform treatments and less waste. Combined with the Baseline HD, Outback S3 and eDrive TC can provide a higher level of accuracy, a necessity for precision applications. Outback S3 is also expandable to work with Outback Automate, an automatic boom control system that monitors and controls individual sprayer sections to help minimize overlaps and skips.
