HOW TO USE C-MAP ELECTRONIC CHARTS TO CATCH MORE FISH – TIPS FROM THE PROS

With today's cutting-edge GPS/Chart Plotters and detailed electronic cartography, you can easily chart a course to the most productive fishing areas in any selected region. These advanced electronic tools help you navigate to specific hot-spots, mark them, and plot strategic drifts. Here's how some experienced fishing pros use their advanced chart plotters and CMAP electronic chart cards significantly increase their fishing success:

Finding and Fishing Key West Patch Reefs
By Capt. Robert “RT” Trossett
Boat: 36 Yellowfin center console

The sandy sea bottom around Key West, Florida is scattered with small coral outcroppings – known as “patch reefs” -- that are natural fish magnets. A variety of fun-to-catch fish like various snappers, groupers, barracuda, African Pompano, cero mackerel and even king mackerel can be found in and around these reefs, making them a reliable destination for private boat anglers.

“I love the patch reefs, because of the variety of fish and the fact there’s usually always something biting,” said Robert “RT” Trosset, a world-famous guide with about 150 current and pending I.G.F.A. world records to his credit. RT offers this trip of tips for anglers on using C-MAP electronic charts:

Set up with Pinpoint Accuracy: Proper boat positioning is key to fishing all reefs, wrecks and structure. Anchor too far away – your chum won’t reach the reef and have the desired effect. Too close — you’ll overshoot the reef, or get broken off by bigger fish. With a highly accurate GPS and C-MAP charts, you can always be set up no matter what the wind or current is doing.

Check Your Perimeter: Look for predatory gamefish like barracuda, jacks or mackerel to be attracted to the activity your chum as created. They will frequently stay around the outside edges of the reef, so try trolling around the outskirts if you want to target them.

Record Your Success: A GPS/chart plotter C-MAP electronic charts lets you store data like an electronic fishing log, with dates, times and what you caught. You’ll quickly figure out patterns as to which areas produce best during certain conditions.

Catch Kings Like a Pro
By Capt. Bob Clement
Boat: Fountain 34 CC

Bob heads up the eight-boat professional Southern Kingfish Association (SKA) 401K Fishing Team. He hits more than 12 tournaments a year up and down the Gulf of Mexico -- including the prestigious SKA National Championships – honing his talents for finding and catching this fast predatory gamefish.

Together with his wife and team partner Capt. Julie Clement, Bob offers these tips on how using your chart plotter and C-MAP electronic charts can help novices and experienced weekend warriors catch more king mackerel on every trip.

Plan With Your Plotter: Our whole team sits down the evening before to plan the next day using our chart plotters. We pinpoint the locations we want to fish, enter the numbers, and when morning comes, we just put the pointer on the first spot and hit go. With a lot of water to cover and a set weigh-in time, you have to make the best use of every minute.

Troll More Effectively: My C-MAP charts show me the bottom structure I’m looking for – roll downs, ledges, and drop-offs -- so I can pick out the contours I want to fish. You want to troll right on a contour line where the fish are going to be. By using your chart plotter, you won’t waste time veering off course or duplicating unproductive trolling patterns.

Mark Every Strike: As soon as we get a strike, we hit “event” on our plotter. Then we go right back to that area. Kings usually run in pairs or small schools and are attracted to an area by bait. By immediately hitting the same water you can usually pick of another one. By returning immediately to the same zone, you narrow down your search and spend more time fishing where the fish are.

Northeast Striper Tips
Capt. Jennifer Clarke
Boat Contender 31 CC

This Martha’s Vineyard, Massachusetts resident is not your typical lady angler – or for that matter, your typical striped bass pro. Her idea of a great time is “being in my boat, running in bad water, hunting big stripers by myself.” Among this seasoned pro’s numerous tournament wins and angling achievements was topping a field of prestigious professional anglers as the American Striper Association’s 2001 Angler of the Year.

Because she likes to hunt stripers all by herself in challenging weather and water conditions, Clarke relies heavily on her Simrad CA-42 combo unit and detailed C-MAP electronic charts. She offers these tips that striper anglers of all kinds can use to fish more effectively.

Pinpoint Critical Structure: In areas without a lot of bottom structure, it’s important to find what structure there is and fish tight to it. For example, the Chesapeake Bay doesn’t have much structure, which makes finding and following the underwater river channel critical to success. Your chart plotter and C-MAP charts will help you find these areas and fish right along the edge.

Work the Rips: Everybody knows to find striped bass along the “rips” created by strong tidal flow. Your chart plotter and C-MAP electronic charts can help you fish these areas far more effectively. Stripers won’t be evenly distributed across these areas; they’ll be stacked up in key ambush areas. Whether you’re drifting or trolling, mark every strike or hookup on your plotter and you’ll soon have a graphic pattern, of where the fish are. Then narrow down your hunt to these fishy areas.

Find the Sandy Shoals. If I see a sandy, finger like shoal on my C-MAP charts in 15 to 40 feet of water, I’ll often troll the area with wire line. Stripers might stack up on top of the shoal or along the edges of the drop off, and by using my fishfinder and electronic charts together I’m able to target the fish zone exactly. You don’t want to have to change the depth of your troll, and you definitely don’t want to drag your lures or umbrella rigs on the bottom.

Catching Wallhanger Walleye
Perry Good
Boat: 2025 Lund

Angler Perry Good works hard to stay on the top of his game – and his game is catching big walleyes. That’s why he is consistently a top finisher on both the PWT and RCL Professional Walleye tours, and is among the nation’s top all-time money winners. Life on the road is hard, the fish are tough and the competition is even tougher. Good counts on his Raymarine chart plotter and C-MAP’s detailed bottom contour charts of the nation’s most popular lakes and inland waters to give him the edge. He offers this advice to help you catch more fish, too.

Focus on River Channels. In many reservoirs, walleye will often be located along old river channels. The detail of C-MAP’s Super Lakes electronic charts will help find these channels and position your boat over them. By referencing your depthsounder you can search for where the walleye are holding and present your baits or lures in the best way.

Repeat Suspenders. In big waters like the Great Lakes, walleye can be suspended anywhere there’s food. You won’t always find them near structure, so you need to stay on the fish once you find them. My Raymarine and C-MAP charts help me follow the schools of fish by saving the location of each strike. When I troll through the same area again, it’s not unusual to pick up another fish or two in the same spot.

Practice Makes Perfect: In tournaments, you practice fish before the event and save all he data about where you fished and where you caught fish. When the money’s on the line, you’ve got a good idea of the patterns and the C-MAP charts put it right in front of you. Recreational anglers can do the same thing by building a database of trips to their home waters and marking where fish were holding and where they were caught. Whether you’re a pro or an amateur, it’s all about learning from what you’ve done before.
