The debate surrounding live sonar in musky fishing has reached a rolling boil, drawing sharp lines between tech-focused anglers and traditionalists who vow never to use it. Many users ignore potential impacts on fisheries, while critics warn of imminent population crashes. However, the reality of extended live sonar use is far more nuanced than either side typically acknowledges.

A major misconception is that using live sonar strictly means "sharpshooting"—scanning open water to target individual fish at ranges up to 200 feet using multiple specialized transducers. While extreme setups exist, most anglers utilize the technology far more moderately. Many turn on live sonar only when seasonal movements draw muskies into open basins. Others use it for precise boat control along structure, to fine-tune lure actions, or to detect deep-following fish that remain invisible to the naked eye. In every case, live sonar serves as a tool to accelerate pattern learning. Traditionalists who reject it outright simply deny themselves valuable opportunities to better understand musky behavior.

Predictably, widespread live sonar use has impacted musky fisheries—just not in the catastrophic way critics feared. Muskies possess a remarkable capacity to adapt to angling pressure, and live sonar is no exception. While evidence that muskies can directly feel sonar waves remains anecdotal, they unequivocally recognize when they are being hunted.

Pressure in open basins has driven many muskies to relocate to unexpected positions. Those that remain in open water have grown increasingly boat-shy and wary of standard presentations. Anglers frequently exacerbate this by repeatedly casting at non-responsive fish, effectively teaching them what not to bite. As a result, the feared population crash has not materialized; instead, these fish have simply become far harder to catch.

Ultimately, live sonar has not ruined musky fishing; it has merely accelerated the evolutionary chess match between angler and prey. The initial era of easily fooled basin muskies has closed, replaced by a dynamic where the fish adapt almost as fast as our electronics advance. The true value of live sonar lies not in turning fishing into a point-and-click game, but in sharpening our understanding of how fish react to pressure. As the technology continues to evolve, the anglers who succeed won't just be those with the newest screens, but those who use that feedback to refine their approach and respect the adaptability of the fish.

September has a reputation for change. Cool nights return, daylight disappears earlier every evening, and the first yellow leaves appear along the shoreline, prompting musky anglers on Canadian Shield lakes to start thinking about fall. However, one of the biggest mistakes an angler can make during early September is fishing for a season that has not actually arrived.

Above the surface, early September signals autumn. Below the water, conditions often remain surprisingly familiar. Until a meaningful cold front or a major drop in water temperature occurs, muskies continue using many of the same areas, structures, and feeding opportunities they relied on through late August. The lake simply moves at its own biological pace, regardless of what the calendar says.

Musky fishing has always rewarded confidence, but using short-term outcomes to judge your strategy can be dangerous. You can make an excellent decision and catch nothing, or make a poor decision and land a 50-inch fish. Anglers naturally crave immediate feedback, but muskies rarely provide it on demand. Your real job is simply to improve the quality of the opportunities you create. Focus on the variables within your control—boat positioning, casting angles, lure depth, retrieval speed, and execution—rather than whether a fish decides to strike. Instead of asking if a spot produced, ask whether it was still the right water to fish.

By late August, Shield fisheries settle into predictable positioning around established bait, islands, rock complexes, and weed edges. When September arrives, anglers often abandon this rich history overnight to throw massive lures or hunt deep "fall spots" simply because the month changed. Until water temperatures make a substantial downward move, sticking with your strongest late-summer data is far more effective. Return to structures that held bait consistently, check the depths where you recently contacted fish, and pay attention to repeatable elements like wind direction and rock type. Early September is rarely the start of a brand-new pattern; it is usually the continuation of your best summer strategy.

Keeping track of your history also helps distinguish random events from actual patterns. Catching one musky on a rock point might be luck, but encountering three fish across similar points or structural edges signals actionable information. Once a pattern emerges, your goal is to reproduce those specific structural and environmental conditions across the lake to reduce randomness and shift the odds in your favor.

Eventually, the lake will shift. A sustained temperature drop driven by cold nights and strong winds removes accumulated summer heat, altering the character of the water. Only when these environmental changes occur should you adjust your tactics. Watch for shifts in forage locations, inspect vegetation for signs of deterioration that push fish off shallow edges, and notice if muskies move from shallow reef crowns to deeper breaks.

Experience never guarantees control over muskies, but it allows you to identify and refine the variables you can influence. Take your summer information into September, make adjustments only when the water temperature truly demands it, and let the fish show you what comes next.

New for last year from Kramer Brothers tackle was their 875 Crank (so named for its 8.75-inch length) and this year has seen the arrival of a smaller model, the aptly named 625 Crank. Our experience has been exclusively with the 875 Crank, so our focus will remain with that version.

The 875 weighs in at a hefty 3.8 ounces, producing slow, head-down rise when paused. Its typical running depth is around 5 feet. The bait is constructed of a strong ABS polymer that holds up well to impact and abrasion. The diving lip is molded into the body rather than attached during construction for outstanding toughness. The bait has very loud rattles as well for added musky-attracted capability.

There is no mistaking that this lure was modeled after the Storm Flatstick (which is sadly out of production). However, the 875 Crank incorporates subtle changes in shape, weighting, and construction compared to its predecessor that give it a slightly different action and better durability. While the 875 Crank is highly effective when it is retrieved straight, musky crankbait experts can bring the bait to life in many ways. The slow, head-down rise gives the anglers supreme control of the bait’s action. Slack-line twitches allow the bait to walk in place from side to side. Ripping upward on the 875 will bring out the most erratic action, with the bait skittering to either side or cutting up or down in the water column, depending on the timing of each rip. This technique can be incredibly useful when triggering a muskie that is near the boat, but not yet at boat side. In the figure eight, the 875 Crank corners like it is on rails, refusing to roll over on its side in the turns (unlike many other popular flat-sided crank baits).

The best use of this bait is probably over rocks and other non-vegetated cover. The durability of the lip allows the bait to shrug off all but the most violent contact with rocks. In the weeds, the slow rise and strong side-to-side action of the bait increases the tendency of the bait to become fouled, but with a subtle hand and careful attention the 875 Crank can be worked over weeds (if not easily through them).

Don’t mistake follows for action. Muskies are often hyped up this time of year. If you’re getting follows but not strikes, it probably means your timing is off or your presentation isn’t quite right.
