Chumming Tips from Guys Who Actually Fish

Chumming looks simple on paper. Then you’re out there watching half your bait drift off with the current instead of pulling fish in. These are the chumming tips that actually move the needle — not theory, just what works on the water.

Bait selection

Sardines, squid, and cut bait all work, but they’re not interchangeable. Sardines put out a strong scent trail and break down fast. That’s good for building a slick quickly. Squid holds together longer. That matters if you’re chumming in current and don’t want to reload every five minutes. Cut bait from whatever you’re already catching on-site is often your best option. It matches what’s actually in the water that day. Whatever you pick, fresher bait always beats older bait sitting in a cooler.

Chumming tips: depth matters more than volume

Most anglers overcompensate by throwing more chum, when the real issue is depth. Surface chumming works for species holding high in the water column. But pelagics like tuna, wahoo, and mahi are frequently feeding 20-80 feet down, sometimes deeper. Getting your chum down to where the fish actually are is one of the biggest upgrades you can make. That beats letting it scatter at the surface. Whether that’s technique or using a dedicated chum dispenser built for depth control, depth control changes everything.

Reading your slick

A good chum slick isn’t just about what you throw — it’s current and wind working together. Watch which way your slick is actually drifting before you set up, not just which way the wind’s blowing. Current near the surface can run a different direction than current at depth. What looks right from the boat isn’t always right 40 feet down.

Species-specific notes

Tuna and mahi respond well to a steady, slow chum line rather than one big dump. Kingfish and wahoo often hold tighter to structure — wrecks, rigs, reefs. A concentrated chum drop near structure can outperform an open-water slick for those species. Bottom dwellers like snapper and grouper respond better to chum that actually reaches the bottom. Chum that disperses on the way down rarely gets there.

Common mistakes that kill a chum slick

A few things show up over and over on slow days. Chumming too fast and burning through bait before fish show up is one. Ignoring current direction and setting up on the wrong side of the boat is another. So is using chum that’s already lost its potency from sitting out too long in the heat. Fishing a slick you built ten minutes ago in different conditions is another classic mistake. Current and wind shift fast, and your slick shifts with them. Small fixes, but they add up to a lot more fish in the box.

None of this replaces time on the water. But these are the chumming tips that actually separate good trips from great ones.

What's in the Box

Every Bait Bomber ships ready to fish: saltwater-activated LED light, swivel, and 150 feet of cord, wound and ready to spool into a bucket, plus the Bait Bomber unit itself. Unscrew the plunger, place the LED light inside, and you’re set. Tie off at the length you need, load it up, and you’re ready to drop.

Care & Maintenance

A little upkeep keeps your Bait Bomber ready for the next trip. Before installing the light, add a light coat of silicone grease to the plunger threads. After each use, remove the light and let it dry before storing. When you're done for the day, keep the included spool noodle inside the unit to protect it and keep your cord tangle-free.

How It Works

Drop bait over structure and small fish show up first — they're always first to the scraps. After a little time, bigger fish move in and push the smaller ones out once they sense there's real food around. That shift is the mechanic the Bait Bomber is built around: get bait in the water and let that natural pecking order do the work of pulling bigger fish in.

How to Use

Structure / bottom fishing  - Yellowtail, Snapper, etc —Anchor over structure, drop your Bait Bomber, and let it chum steadily. Give it time. The bigger fish won't show up right away, but once they do, they'll take over.

Open-water fishing for pelagics - Tuna  — These fish often hold deep, 100–300 feet down, and won't come up on their own. Drop the Bait Bomber down near where they're holding, then work it shallower in stages to pull the school up toward the surface — instead of chumming from the surface and waiting for them to come to you.

Personal experience: Diving over roughly 1,000 feet of water with no structure nearby, they worked a small dive bag of chum — tossing a chunk every 30 seconds or so. As each piece sank, tuna rose out of the depths to meet it, chunks disappearing while spiraling up through the water column as they fed their way toward the surface."

Load, Drop, Release

Loading Bait Bomber is simple, however you’re fishing it. Using live bait? Point the open end up at the livewell, drop your bait in, and seal it shut — Brett does this straight from the boat’s tuna tube (remove the screw from the head to allow water flow), so the bait stays lively until the moment it hits the water. Chunk bait and fresh dead work just as well, and don’t need a livewell at all — load it straight in and you’re ready to go. From there, the included cord (wound in a bucket for a clean, tangle-free release) gets tied off on the boat at whatever depth you’re targeting. Toss it over the side and Bait Bomber drops nose-first, straight down, like a torpedo (approx. 10 ft/sec). The moment it hits the end of its tether, the tug flips it upside down — and the plunger does the rest, pushing your chum out exactly where you want it, not scattered on the way down.

PRO HACK - Remove screw on head, and cover with finger when deploying - helps plunger disperse the chum.

Live Bait Hack: The Bottle Scooper

Here's one we swear by: take an empty jug (a Clorox bottle works great), cut it at an angle so it looks like an upside-down shovel with a hole in the bottom. Instant bait scooper — no need to buy a specialty net. Scoop, drain, and drop straight into your BaitBomber.

You can either keep the lid on, your use your hand to keep the fish in. 

Bucket

Use any 5-gallon bucket to hold the Bait Bomber and its cord — gives you a stable, tidy platform to transport and hold everything while you prep. When ready: tie the cord to a cleat, pull the Bait Bomber out, fill it with chum, and deploy. The cord unravels smoothly to whatever depth you need.

The Built-In Light

Bait Bomber's built-in light flashes and cycles through colors underwater to make your bait stand out and draw bigger fish in from farther off, even in low-visibility water. Fish are especially responsive to true-green light, which is why it's a favorite among deep-drop and night fishing setups.
