The AquaSpy sensor was viewed favourably enough to win Best New Product Award at Irrigation Australia Ltd’s biennial Exhibition in 2006 and a People’s Choice Award on the ABC’s New Inventors programme <ref>[http://www.whebventures.co.uk/news/story_14.htm WHEB Ventures web site, 2006]</ref>. Staff were employed to build sales of the units through the major retail hardware outlets. Unfortunately volume sales remained elusive.

~~====C-Probe Series 4 – AquaSpy Probe====~~

−

The Series 4 probe was designated the AquaSpy to build on the initial success of the AquaSpy turf sensor. The original unit became the AquaSpy Single Level sensor and the new unit the AquaSpy Multi Level sensor. Whilst earlier capacitance probes were built around a PCB to which brass rings were soldered, the new probe was built around a flexible plastic membrane. Copper tracks laid on the membrane carried the electronic components and formed the new sensor elements. Construction of the new PCB was contracted to Best-tech Manufacturing Company in Thailand <ref>[http://www.besttechmfg.com/Product%20Reference.htm Best-tech Manufacturing Group web site, 2007]</ref>.

Rather than the circular PVC tube employed in its predecessors, the AquaSpy utilised a “D” profile tube. The original intention was for the components on the PCB to sit against the flat edge of the D, allowing the sensors to curl out against the rounded section. A quick modification was soon carried out – adding a former to hold the PCB in the correct position with the sensor elements hard up against the inside of the tube. Like the Series 3, the Series 4 probe relies on a slurry installation into an over-sized hole.
