After June 30, 2022, Defiant will no longer continue support for the FROG-4000.

Note that this does not apply to the newer FROG-5000 model, only the FROG-4000.


After June 30, 2022, Defiant Technologies will continue to make efforts to assist users to repair their own FROG-4000 units, but parts availability is not guaranteed. Due to the increasing scarcity of replacement parts for this instrument, even simple repairs may involve very costly upgrades to hardware and electronics, especially on older FROG-4000s, if the repair is even possible at all. Additionally, no Annual Service Contracts for FROG-4000 will be available after this date.

If you have any questions about this transition, or if you would like to contact us about upgrade options or for a quote on a new unit, don’t hesitate to reach out to us.
