Yes, if the CHIRP signal encompasses 455 or 800 kHz the xducer will likely work with a Humminbird. It will probably work pretty well with a Humminbird even if the resonance frequencies are a bit lower or higher than the ideal levels. Since a CHIRP system works with a frequency range the manufacturer may refrain from presenting frequency data. If this happens, we have to test the xducer ourselves and see what happens.
