The 2017 IonX is compatible with the ultralight bit.

Thank you for the reply’s! I directly contacted Ardisam in Cumberland WI and I qualified for a replacement bit. They sent me the Ultralight bit free of charge. Great fast online customer service. I’ve drilled around 50 holes with around four inches of ice very well as expected. I’ll see how she does below 0° in February.
