John Eaton, Outram

"Being able to drive more accurately, and ensure the whole area has been covered, is a great advantage. It is always important, but particularly so on broken hill country."

"The need for Proof of Placement is coming. We need to be able to demonstrate a responsible attitude, and keep control over what and where we are able to apply."

"It is great to be able to demonstrate to farmers we are doing a quality job, and have the confidence that staff are doing the same."

"Being able to record wind data while working is a good for protecting against false claims for spray drift damage."


Gary Smith, Waiau, North Canterbury

“Its great. Being able to work into the evening to finish jobs, and provide my dairy clients with placement maps has made a big difference”.

GPS Options

Autonomous GPS. Many of our spraying customers use autonomous GPS, which is the standard GPS sold as part of the TracMap package. This will typically give pass to pass accuracy of under 2 metres, but (as with all autonomous GPS receivers), can occasionally be much worse than this.
This means you will need to run a foam marker as well, particularly when it is important to achieve complete coverage with minimal or no overlap.

"E-Diff" GPS. This option typically requires 10 minutes when first turned on at the start of the day to analyse the errors in its position fix and then calculate a correction. After that it will provide about 30cm accuracy on a pass to pass basis. If you are returning to a partially competed job you can correct for the position drift which occurs over time by using the "nudge" feature in the TracMap software.

Differential GPS. We also offer the ability to upgrade to the precision provided by an Omnistar correction signal. The benefit of this option is always knowing you position fix is accurate. Accuracy options include

  • sub-metre, which typically provides under 30cm accuracy on a pass to pass basis, and is good enough to allow you to dispense with a foam marker.
  • 10cm, which is a higher level of accuracy still.

Both options require a monthly (or annual) subscription to acquire the correction signal.
