Introduction to downriggers

Introduction to Controlled Depth Fishing

Undoubtedly there are many fishermen familiar with the methods and use of controlled depth fishing. During the mid 1960's the state of Michigan introduced Pacific salmon into the Great lakes in an attempt to revitalize its sport fishing industry. From this successful transplant, new fishing techniques and equipment were developed. One such method was controlled depth fishing which enabled fishermen to place a lure at a desired depth by utilizing downriggers. Because of the varying factors (water temperature, thermocline, weather, tides, time of day, or time of year) it is necessary for successful fishing to maintain specific water depths that coincide with fish movements and feeding patterns.

One essential feature of the downrigger is the depth meter or gauge that indicates lure depth. This allows the angler to control as well as return to specific depths where fish have been caught. Due to the success of controlled depth fishing, downriggers are now being used throughout the world to catch a wide variety of species in both fresh and salt water. Whether fishing for blues off Rhode Island, walleyes in Lake Erie, sailfish off the coast of Florida, or stripers in Tennessee, the use of downriggers will make your fishing more successful and more enjoyable.

Mag 20 DT New Features

Magnum Power

The Mag 20 DT/HS and Mag 20 DT/TS feature improved tolling weight capacity, retrieval rate, and quality. The Mag 20 DTs can now accommodate trolling weights up to 20lbs. The newly improved Mag 20 DTs also feature a high retrieval rate up to 250 feet per minute.

Mag 20 DT/TS Features

The Mag 20 DT/TS (Tournament Series) has an improved appearance featuring a sleek metallicwhite finish. An extremely durable stainless steel spool allows for you to outfit your downrigger with monofilament or “super line”, eliminating the fishspooking vibration and harmonics of conventional downrigger cables. With a heavy-duty, brushed stainless steel telescopic boom, adjustable rod holder, and an Off-Shore Release included, the Mag 20 DT/TS is designed specifically for tournament level fishing.

Battery Alarm

The Mag 20 DT will now beep every two seconds if the battery voltage drops below 9 volts.

Remote Operation with CannonLink

Your Mag 20 DT has the ability to be operated remotely. Utilizing Humminbird Fishing systems featuring CannonLink, you can control up to 6 Mag 20 DT/HSs and/or Mag 20 DT/TSs simultaneously. CannonLink gives you the ability to cycle downriggers up and down, bottom track, change depth, monitor speed and temp* (with Cannon Speed & Temp Sensor), and adjust Positive Ion Control from your Humminbird Fishing System (Matrix™, 700, and 900 Series).

CannonLink Details

The Mag 20DTs connect to the Humminbird unit with the #019095 Mag 20 Master Cable. This cable has an eight-pin plug on one end and a fivepin plug on the other. The eight-pin plugs into the fish finder communication port. Additional Mag 20 DTs are connected to each other in a chain with the #019634 Mag 20 Remote Cable. The last downrigger in the chain must be terminated with the #609198 Endcap plug that comes with the Mag 20 Master Cable. This plug completes the loop allowing the fish finder to get depth and mode information from the Mag 20 DTs. Additional information can be found with the Humminbird fish finder.

The details of CannonLink are described in full in your Humminbird owner’s manual. Any one or all Mag 20 DTs can perform these features with CannonLink only from Cannon:

• Set PIC voltage in 1/10ths of volts

• Go to depth (feet or meters)

• Adjustable descent and retrieve speeds

• Cycle mode; includes upper depth, lower

depth and time at depth

• Bottom-contour following mode, includes wave

height, distance above the bottom

• All up (brings all the weights to the surface

immediately)

• Park height (allows you to set individual

heights to park the ball above the water)

• Disconnect alarm sounds if the remote cable

is accidentally unplugged

The Mag 20DTs communicate through an optically isolated NMEA 0183 standard interface. Each unit is both a listener and a talker to the next unit in the chain. The endcap plug sends the last talker’s broadcast back to the first listener/talker, which is usually the fish finder. Only two sentence headers are used: the standard NMEA ‘$SDDBT’ (SONAR Data Depth Below Transducer) for bottom following, and ‘$PCMAG’ (Proprietary Cannon MAG) for system control. Several features have been included in the remote interface that would allow the electromechanical system to be used for other types of applications

NEW FEATURES

*Note: The CannonLink system outputs data from only one single Speed & Temp Sensor Fish.

MOUNTING & SETUP

Downrigger Mounting on Boats

A downrigger should be mounted where ever it is easy to operate and observe. You want to be able to see your fishing rod and to react quickly. So, choosing a good spot to mount your downrigger on your boat is 99% of the job. Due to the great variety of boats available, mounting your downrigger can be a dilemma. Having proper mounting accessories is essential. Cannon has a complete line of mounting accessories to conveniently mount your downriggers on any boat.

Arrows Indicate Mounting Locations

Mounting Accessories

Deck Plates are necessary when extra strength must be added to the base material of the boat and for attaching the downrigger to other mounting accessories. Gimbal Mounts are designed to fit mediumsized flush mounted rod holders built into the gunwale of many larger fishing boats and cruisers. Only sturdy, high quality rod holders should be used for this temporary mounting system. Gimbal mounts are available in 9” or 12” post lengths.

Clamp Mounts can be mounted at the junction of two rail sections with the aid of two ¼” pieces of plywood. They will protect your rail from any marks from the clamp and provide a non-slip surface.

Side Rail Mounting

Side/Rail mounts can be mounted to a welded T section. They can also be used at the two rail section butt joint. In both installations it is recommended to use a non-slip material, such as rubber or a thin wood sheet, between metal surfaces.

You can also use these for mounting to a very narrow side gunwale. There is a plate provided for back-up with bolts and washers. If the gunwale compartment is foamed in, then wellnuts should be used. It is also recommended to install two additional flat head screws through the top plate for stabilization (you will need to drill and countersink).

NOTE: In no case should this mount be used on fiberglass ¼" thick or less unless it is foamed in.

Pedestal Mounting

Pedestals are used wherever additional height is needed for ease of operation or to clear obstructions, such as handrails.

Caution: When using a pedestal mount or side/rail mount, do not extend the telescopic boom on your Mag 20 DT. The increased leverage will cause excessive strain and possible failure of the mount.

MOUNTING & SETUP

Installing the Base on Your Boat

Decks up to 7/16" thick

Where access to the underside of the deck is not available, the mounting base can be mounted using wellnuts. Use the base as a template to mark locations and drill four 1/2" holes. Mount the base using four 1/4-20 x 4" truss head screws and four wellnuts. Tighten the screws so the wellnuts are firmly compressed as pictured.

Decks thicker than 7/16"

For decks thicker than 7/16", or where the underside of the deck is accessible, mount the base with screws, nuts, and washers. Use the base as a template to mark the locations and drill four 9/32" holes. Use four 1/4-20 x 4" truss head screws and four each flat washers, lock washers, and nuts. Fasten the base to the deck as pictured. NOTE: Wellnuts cannot be used on decks thicker than 7/16".

Decks thinner than 1/4"

Use a Cannon deck plate to prevent deflection and add stability to decks thinner than 1/4". Use the deck plate as a template to mark the hole locations.
