"The Auto-Hover Control system allows much more accurate control of the sub, in all directions. I can put it exactly where I want it and then I can release the controls and it just sits there. It makes piloting a SportSub a breeze!"

The new Auto-Hover Control system uses 4 fixed position thrusters instead of the 2 variable position thrusters of standard subs. All 4 thrusters are computer controlled by a single joystick. There are three available modes of operation:

  • Manual Mode
  • Auto Hover Mode **
  • Auto Target Depth Mode **
    ** Includes Auto Ascent/Descent Rate Control

    With Auto Hold engaged, whenever the vertical thrusters are not being operated manually, the computer takes control of the thrusters and uses them to hold the sub at its current depth. When the pilot wants to change depth, the thumb switch is used to ascend or descend. Once you have reached the depth you want, the pilot releases the thumb switch, and the computer again takes over and will maintain the new depth. Auto Rate Control is operational in this mode.

    With Auto Target engaged, the pilot uses the thumb switch to scroll to a target depth as indicated on a digital readout, then releases control. The sub will ascend or descend (as required, to attain the target depth) and will hold at the target depth once it is reached. Auto Rate Control is operational in this mode.

    The Auto Rate Control function or 'automatic ascent rate control and descent rate control', helps prevent the sub from ascending or descending too quickly (faster than 1 foot per second). This is a significant safety feature.

    This is a basic overview of the Auto-Hover Control System.

    The Auto-Hover Control System is standard equipment on the ResortSub and SurveillanceSub. Auto-Target Depth Mode is an optional add-on. Auto-Hover is available as an option on other models.

    Existing SportSubs can be refit with the Auto-Hover Control system. Prices will vary depending on what equipment your sub has currently.
