iPad's compatible with Jolt:
Second Generation iPads or newer are compatible with Jolt.
However we recommend any Third Generation iPads or higher. Any generation of iPad Airs, Pros, and iPad Minis are third generation so they are compatible with Jolt.
First Generation iPad's are not compatible with Jolt because they are no longer supported by Apple.
*Note: If you are looking to use the Probe you must have a Third Generation iPad or newer. The Probe uses low energy BlueTooth and the Second Generation iPads will not work with this.
