This unit has been extensively tested in Australia, Europe and the USA. Monitoring of these tests has allowed Minelab to tailor the scanner to provide optimum performance and sensitivity under all operating conditions. Aimed at the Security Professional the MF1 Security Scanner is a highly sensitive detector that has been designed and built to meet the toughest standards for efficiency and operating conditions. The MF1 scanner is the only detector to have automatic recalibration ensuring maximum set sensitivity from the moment the unit is switched on. The auto recalibrate function makes the MF1 Security Scanner one of the worlds easiest scanners to operate whilst maintaining maximum operating performance without drift due to temperature or other environmental conditions. The MF1 has very low battery drain giving extended battery life and making it highly efficient in the field. In developing the MF1 hand held security detector Minelab paid particular attention to the qualities and sensitivity of competitor models. We believe the MF1 outperforms competitor brands for both general performance and sensitivity to metal objects.
