Meet Captain Pete Rosko:Pete Rosko is a legendary figure in the world of sport fishing, a man whose name resonates deeply with those who share a passion for the waters. Known for his groundbreaking innovations in lure design and his unparalleled ability to teach anglers the art of fishing, Pete’s influence has left an indelible mark on the industry. His story is one of pure dedication, ingenuity, and an unwavering love for the sport. Using his expertise as a dentist, Pete is best known as a lure inventor. His innovation brought us the versatile and ever popular Sonic Baitfish lure.
Vertical jigging represents the most precise and versatile fishing technique available to anglers, offering unmatched opportunities for targeting suspended fish across both freshwater and saltwater environments. This guide combines decades of expertise from Captain Pete Rosko, inventor of the revolutionary Sonic BaitFish and distinguished master angler, with proven strategies for achieving success on the water.
Vertical jigging differs fundamentally from traditional casting or trolling techniques by placing your lure directly in front of fish with surgical precision. The technique involves dropping a weighted lure straight down beneath your boat or kayak, then working it vertically through the water column using controlled rod movements.
“This is the most versatile, precise, and effective, of all presentations in sport fishing…including trolling, casting, mooching and speed jigging,” emphasizes Captain Pete Rosko. This foundational principle explains why serious anglers across all species and environments have adopted vertical jigging as their preferred method.The technique’s effectiveness stems from its ability to target fish relating to specific depths, structures, or suspended bait schools. Unlike horizontal presentations that must cover large areas to find fish, vertical jigging allows you to work precise locations where electronics show fish activity.

Rod Selection:
The Foundation of Control Your rod choice fundamentally determines jigging effectiveness. Rosko consistently emphasizes using “a rod that has a fast action taper” with most bend occurring in “the one-third tip portion of your rod”. The butt section should remain “pretty stout” and never bend “at the handle” but rather start flexing “about three quarters of the way towards your rod tip”. This specific rod design serves multiple critical purposes:
A medium-heavy, 6-foot spinning rod with these characteristics provides the backbone necessary for effective vertical jigging while maintaining the finesse required for light presentations.
“Braided line not mono” represents one of Rosko’s cardinal rules for vertical jigging. Monofilament “stretches too much and you can’t telegraph the structure that you’re fishing”. The no-stretch properties of braided line provide superior hook sets and allow anglers to feel every nuance of bottom composition and structure. However, never attach braided line directly to your lure. “Braided line is very very soft and it’ll collapse onto your lure and on your hook and you’ll get constant hook to line fouling,” warns Rosko. Instead, use approximately “2 feet of fluorocarbon leader” which is “stiffer and lays more horizontal than the limp vertical lay of braid”.
“Without a sharp hook nothing else really matters,” declares Rosko emphatically. The hook sharpness test is straightforward: “If that hook doesn’t dig into your thumbnail it’s not sharpened. If it slides off you need to sharpen it”.
Use a fine-tooth file and “lightly remove the burrs from all three sides” by triangulating the point—one pass on each side and the top. This attention to detail becomes critical because “fish are attacking a metal jig they’re slashing at us”, making razor-sharp hooks essential for successful hookups.
The Sonic BaitFish’s revolutionary design features three attachment points that completely transform vertical jigging approaches. “This is the only lure on the market with three different attachment points for flutter and vibration,” explains Rosko.

Each attachment point produces distinct actions optimized for specific conditions:
PRO TIP: This attachment only works effectively when your line goes straight down and NOT at an angle. If you see your line angling off that’s a time to attach the snap to either your nose or to your tail simply because it’ll cut through the water a lot quicker,” advises Rosko.
The back attachment creates a “slow fall” that won’t reach target zones effectively in current or wind.

The Finesse Approach: Surgical Precision Vertical jigging with the Sonic BaitFish attached to the back requires a completely different approach than traditional jigging methods. “This is the closest thing to fishing with live bait because you’re dead sticking that lure,” explains Rosko.
The lure hangs “completely horizontal” rather than vertically like traditional metal jigs. The rod movement should be minimal and controlled. “Nice easy lift…slow lift and drop it back” represents the proper cadence.
PRO TIP: Avoid aggressive jerking motions used with conventional jigs. I don’t want you to do that with the Sonic BaitFish when it’s attached to the top of the back.
High-Speed Vertical Jigging Method
For aggressive fish or when covering water quickly, high-speed vertical jigging creates an “escaping prey” presentation. Drop the jig to bottom, then use “a rhythmic motion that creates a vertical walk-the-dog action” while continuously cranking the reel. This technique works by “whip that rod tip as you are continually cranking” creating a jig that “darting through the water column all the way back up to the surface”.
PRO TIP: This presentation is deadly effective for pelagic game fish tunas king mackerel wahoo dolphin cobia” and all jack species.
Slow-Pitch Jigging: Bottom-Focused Precision
Slow-pitch jigging targets bottom-dwelling species with methodical presentations. Use “more of a slower you’re jigging up jigging up jigging up” motion with deliberate “pull up pull up pull up” movements.
PRO TIP: This technique excels when fish are holding tight to structure or in negative feeding moods. The slower presentation gives fish more time to examine and strike the lure.
Critical Fish Finder Skills
“There are three critical things in fishing that you need to know: number one is having a quality jig, number two is having a quality electronic fish locator, and number three is taking that knowledge and applying it to the screen,” states Rosko. The objective is precise lure placement. “Place your sonic baitfish right in front or just above the fish mark”. This precision placement separates successful vertical jiggers from average anglers.
Structure Identification and Targeting
Modern fish finders reveal bottom composition, structure, and suspended fish with remarkable clarity. Learn to identify:
Position your lure at specific depths shown on electronics, working it just above marked fish for maximum effectiveness.
Weight Selection Philosophy
“When you’re fishing this kind of structure go as light as possible to reach your target,” advises Rosko. Lighter lures offer significant advantages: “If you use light lures you won’t get hung up as much” and are “easier to un-snag”. Additionally, “neutral, or negative, fish very seldom respond to a large offering. However, they will respond to a tidbit offering more times than not”. This principle becomes critical when fish are inactive or heavily pressured.
Color Selection Based on Condition
Environmental conditions dictate optimal color choices. “We’ve got an overcast day here and I’m using a silver finish which isn’t too bad. It’s great when the sun is out to reflect…better finish on a day like this would be glow white or chartreuse glow”.
Optimal Color Guidelines:
Walleye Vertical Jigging
Bass Applications
Saltwater Versatility
The Learning Mindset
“This is a continual education series both for you and both for me,” reflects Rosko. Mastering vertical jigging requires patience, practice, and continuous refinement of technique. The precision required may seem daunting initially, but the rewards justify the learning investment.

The beauty of vertical jigging lies in its universal application across species and environments. “The Sonic BaitFish was invented with two primary goals in mind: ease of use and versatility. Ease of use means that anyone—regardless of age—who can hold a rod can catch fish with the Sonic BaitFish once those fish are located,” explains Rosko. This accessibility makes vertical jigging an ideal technique for anglers of all skill levels, from beginners learning precision fishing to experts targeting specific species in challenging conditions.
Vertical jigging represents the convergence of precision, technique, and fish behavior. Master these fundamentals—sharp hooks, proper equipment, precise lure placement, and controlled rod movements—and you’ll discover why Rosko considers vertical jigging “the most precise presentation, of any fishing technique in sport fishing”. The technique’s effectiveness, combined with its conservation benefits and universal applicability, makes it an essential skill in every serious angler’s repertoire.
Whether targeting suspended salmon in Pacific waters, walleye in Great Lakes tributaries, or bottom fish along coastal structures, these time-tested principles will elevate your fishing tactics and deepen your appreciation for this angling art.
