WARNING! This device should not be used as a navigational aid to prevent collision,
grounding, boat damage, or personal injury. When the boat is moving, water depth may
change too quickly to allow time for you to react. Always operate the boat at very slow speeds
if you suspect shallow water or submerged objects.
WARNING! Disassembly and repair of this electronic unit should only be performed by
authorized service personnel. Any modification of the serial number or attempt to repair the
original equipment or accessories by unauthorized individuals will void the warranty. Handling
and/or opening this unit may result in exposure to lead, in the form of solder.
WARNING! This product contains lead, a chemical known to the state of California to cause
cancer, birth defects and other reproductive harm.
NOTE: If you have a chartplotter, the Downrigger View will not show sonar or depth. Caution
should be exercised when the CannonLink™ Downrigger Controller is used in conjunction with
a chartplotter. It is the user's responsibility to be aware of the operational depth as the
chartplotter does not report back depth as a traditional fishfinder will.
NOTE: Fishfinder may require a software upgrade to be compatible with Cannonlink™
accessory. See www.humminbird.com for more information.

How Downriggers Work
Downriggers allow you to catch fish you otherwise couldn’t even touch. By
viewing sonar, temperature at depth and clarity information on screen while
piloting the boat, you can monitor and position downriggers in real-time to the
optimal depth to vastly increase the catch. Your Humminbird® CannonLink™
Downrigger Controller makes operation of up to six Cannon™ Mag 20 DT or Mag
20 DT/HS downriggers and one optional-purchase Cannon™ Speed-N-Temp
Sensor incredibly easy.
• Automatically deploy or retrieve downriggers directly from any Fishing
System.
• Set the downrigger operation mode to Manual for complete control,
Bottom Track to maintain distance off the bottom or Cycle to
continuously move the downriggers between two depths.
• Monitor the downrigger depth and operation graphically on-screen
combined with the sonar graph.
• View temperature at depth, speed-through-water and water clarity on
the Fishing System screen when using the optional-purchase Cannon™
Speed-N-Temp Sensor.
• Simultaneously or individually control up to 6 Cannon™ Mag20 DT and
the Mag20 DT/HS downriggers.
NOTE: Your Humminbird® CannonLink™ Downrigger Controller only works with
Cannon™ Mag 20 DT or Mag 20 DT/HS downriggers or the optional-purchase Cannon™
Speed-N-Temp Sensor. Although this manual discusses all three products, only the
CannonLink™ Downrigger Controller is included with this manual.
Using the controls on your Fishing System, lower (activate) or raise (park)
downriggers, hold your downrigger a specific distance from the bottom, move
downriggers between two different depths, and adjust the Positive Ion Control to
change the electrical charge emanating from your boat. You can even see
temperature and water clarity (at depth and speed) at the downrigger ball
on your control head screen when using the optional-purchase Cannon™
Speed-N-Temp. You’ll never be shorthanded again, since you can make
adjustments from the helm, while your mate rigs the lines and brings in the fish!

Positive Ion Control (PIC)
Positive Ion Control (PIC) is a feature of the CannonLink™ Downrigger
Controller that allows you to use electricity to control this charge on your
downriggers, so that it remains constant at a specified set positive voltage. It is
important to prepare your boat's electrical condition before installing the
CannonLink™ Downrigger Controller and downriggers to make sure that the
Positive Ion Control feature will work most efficiently. The Positive Ion Control
system applies a variable .2 to 1.2 Volts to the trolling cable at all times.
NOTE: All metal parts, including the hull (if metal), motor shaft outdrives, and thru-hull
fittings, must be connected together using a bonding wire. The zinc anodes placed on
your hull, propeller and other parts of your boat protect functioning metal parts from the
natural corrosion that occurs when metals of different types that are physically or
electrically connected are immersed in seawater. If your boat and zincs are set up
correctly, the voltage on the stainless steel downrigger wire of your downrigger(s) should
be positive when submerged.
Downrigging Tips
Try the cycle mode on the CannonLink™ Downrigger Controller to create a
unique "action" in your lure. Many times this will trigger a strike.
When you have your downrigger set at the depth you want it, don't forget to set
your clutch correctly. It is designed to "slip" in case your weight hangs up in
rocks. This will avoid breaking the line and losing expensive lures or weights.
It's always a good idea to carry extra releases, weights, terminator kits and
replacement cable in the boat. That way if you break or lose something while
fishing, you can simply re-rig and not spend time out of the water.
Always keep your boat in gear when setting your downriggers. Allow the weight
to descend slowly to avoid tangles. To be sure your lure is working properly,
check its action at trolling speed.
If you notice that you're marking bottom-hugging fish, such as walleye or lake
trout, try using the Humminbird® CannonLink™ Downrigger Controller exclusive
bottom tracking feature.

Your Humminbird® CannonLink™ Downrigger Controller allows you to control up
to six Cannon™ Mag 20 DT or Mag 20 DT/HS downriggers easily, as well as one
optional-purchase Cannon™ Speed-N-Temp Sensor, using your Humminbird®
control head. The following functionality is supported by your Humminbird®
control head when it is connected to the CannonLink™ Downrigger Controller:
• Vary the strength and type of electrical charge of the boat using Positive
Ion Control (PIC);
• Setup each downrigger attached to your control head, and then change
the settings during use;
• View settings for all downriggers connected to your control head at
one time;
• Activate each downrigger separately, or all downriggers at once;
• Pull all downriggers up at the same time, or individually.

CannonLink™ Downrigger Controller Installation Overview
Before installing your CannonLink™ Downrigger Controller, you should set up
your boat for Positive Ion Control. You will then connect your CannonLink™
Downrigger Controller to your Humminbird® fishing system control head
and up to 6 CannonLink™ downriggers (plus one optional-purchase Cannon™
Speed-N-Temp). You may also connect the CannonLink™ Downrigger Controller
as part of a daisy chain of other Humminbird® accessories, by using the included
daisy chain cable.
NOTE: The CannonLink™ Downrigger Controller will only support up
to 6 CannonLink™ downriggers plus one optional-purchase Cannon™
Speed-N-Temp Sensor. Do NOT connect more than one optional-purchase
Cannon™ Speed-N-Temp Sensor, as more than one may result in
system instability.
NOTE: Only attach two downriggers to one battery. Humminbird® recommends
that the downriggers have their own separate battery, and NOT be powered off
the battery used to start the main gasoline engine of the boat. Confirm that all
batteries are fully charged prior to each use.
NOTE: Installation of the terminator plug and proper grounding are both
essential for proper operation. Confirm that each downrigger's NEG terminal is
connected to the NEG terminal(s) of the boat's main/engine battery(ies).
NOTE: In the event that the downriggers lose power during operation, you
must manually park the downriggers. You must also re-start the Humminbird(r)
control head before you can resume normal operation.
NOTE: Confirm that all power connectors are securely fastened to the batteries
and that all communications cables are securely fastened prior to each use.
