A good entry level radar detector for users in Western Australia on a budget. This unit is fairly sensitive to LASER making it our second choice for price & performance in WA. We highly recommend choosing the V1 as our number one choice, however we also sell this product as a second option.

The Whistler Pro-78GXi has front and rear laser sensors and also features the unique ability to isolate specific laser pulse rates to eliminate any laser false alerts from laser cruise control and laser collision avoidance systems through its selectable menu system. The Whistler Pro78GXi features an excellent all-new ergonomic and user-friendly design that provides a new level of operating convenience. The Whistler Pro-78GXi is an excellent high performance unit.

Latest high performance design with KA-MAX, KA Signature ID and Laser Signature ID...New 44mm (1.45”) OLED display provides better contrast and brightness; alerts detected include signal strength, and indicates engaged modes of operation.
