OPERATION OF THE SUPER THIRTY 11 IN VERY SHALLOW WATER
The Humminbird Super Thirty II will operate in the same manner as our Super 60 except the unit with its wide graduations is ideally suited for shallow water applications. This unit measures to 30 feet on the first revolution and will operate satisfactorily in water depths of 100 feet or more. Since the unit is designed for shallow water, we recommend that it be mounted forward and in conjunction with a trolling motor mount. In certain areas of the country, such as Florida, where many bodies of water rarely exceed 30 feet in depth, the Super Thirty II can be successfully used as a console mount. When operating the Super Thirty II in water deeper than 30 feet, simply move the selector switch to the 60 foot setting. The range on the first revolution will then be up to 60 feet as shown on the inner dial.
The slightest change in depth can readily be detected with the Super Thirty II. We recommend you start with a minimum amount of gain, and increase it as needed.
If the depth continues past 60 feet, the bottom signal will continue past zero and you will continue to get an accurate depth reading by adding the additional depth to 60 feet.
