iTroll G3 Max Throttle and Secondary Cruising Speed functions

Max throttle elevates throttle in case you need to avoid an obstacle or clear a shallow spot that you encounter (raising speed raises your baits).
iTroll has secondary cruising speed that allows you to raise and then maintain your throttle at a level higher than where the dial is set to. You can release this speed and drop to the speed at which your dial is set. You did not disturb the dial at all!
If you sped your boat up with the dial or pushbuttons, you would have lost your trolling speed.
