Humminbird released new updates for XX8 units. Added jigging mode. *Jigging Mode - this is a selection in the 2D Sonar Express Menu. It allows the user to select the sonar ping pattern for use while vertical jigging. When turned ON the ping pattern will be: 200 kHz, Left SI Beam, Right SI Beam, 83 kHz, repeat. With this mode turned OFF the ping pattern will be: 200 kHz, Left SI Beam, Right SI Beam, 83 kHz, Left SI Beam, Right SI Beam, repeat. Basically this feature prioritizes the 2D beam over the SI beam.. I checked my account it's available for my 898HD and 1198.
