Digi-Troll IV Manual - Cannon Downriggers

OPERATING & PROGRAMMINGOperating the DigiTroll IVFeaturesThe Digi-Troll IV offers you the mostadvanced features available in a downrigger.• Variable Positive Ion Control.• Large LCD digital display for weight depthand easy programming.• User selectable Master/Slave operationallowing you to chain several Digi-Troll IVstogether for bottom following with only onetransducer.• (Optional transducer and interfacing cablerequired)• Cycling mode allows the weight to be cycledbetween two programmable depths.• Store five programmable weight depths thatcan be selected at the touch of a key.• AUTO-UP key to quickly raise the weight towater surface.• Bottom depth monitor mode allows yourdownrigger to be used as a depth finder(optional transducer required).• A permanent storage memory to retain all thesettings.• Variable speed operation• High efficiency motor• A low voltage warning system.Bottom FollowingThe Bottom-Following mode is designed tohelp you fish consistently near the bottom. Thismode of operation requires:1) A downrigger configured as a Master unit(see programming instructions)2) optional sonar transducer attached to yourMaster downrigger and mountedaccording to the instructions in thismanual.3) if you have more than one downrigger andyou wish to bottom follow with all yourdownriggers, they must be configured asSlave units and chained to the Masterunit using the optional interface cable(s).In the bottom following mode, the Digi-Troll IVmaintains the weight at a fixed distance abovethe bottom. In order to avoid continuous weightadjustments due to minor changes in bottomdepth and boat motion caused by wave action,you have the ability to adjust the responsivenessof the weight. You can also define the maximumdepth that you wish the weight to go to,regardless of the bottom depth.Caution:You must ensure that the distance above thebottom is great enough to keep the weight frombecoming tangled in the weeds, etc.CyclingUsing the Cycling mode, you can fish a depthband where fish may hover under certainconditions. An example is a band where the fishseek the most suitable temperature. Allparameters are programmable by the user.Caution:In order to keep the weight from touching thebottom, make sure that the bottom is wellbelow the band that you have selected.12
