Spectre Top Down

Massive Size Samples Straight Off The Truck

In response to demand from high volume producers and packhouses, Hectre has developed Spectre Top Down.

With Spectre Top Down, sample sizes in the thousands are collected in seconds via a fixed camera placed at receiving. As flatbed trucks pull into receiving they pass under the Spectre Top Down camera and Hectre's technology detects and sizes fruit from the top layer of bins, delivering huge size samples.

Join industry leaders and transform your size sampling process:

  • Fill orders with confidence
  • Improve fruit storage decisions
  • Reduce unnecessary packline stoppages
  • Sustain and enhance your reputation
