Here's what the review says, under features and functions.
The Jackaroo has pretty much every mode we’ve seen on mods these days. You have Power mode (watts), Voltage Mode, Watt Curve Mode, Temp Curve Mode, Bypass Mode, and Temp control mode for Ni200, Ti, and SS. No TCR mode, but the TCR is adjustable in each of the preset modes. The only thing I would consider missing is a pre-heat option in power mode, but you can use watt curve mode for that anyway.
@Shawn Hoefer, does your Jackaroo not have these options/modes?
If not may well be worth contacting Vandy Vape and asking what's the latest version firmware.
