# Bizz Baits Big Thump: the single Colorado spinnerbait built for night > Oversized Colorado blade, 5/0 Mustad hook, low-frequency pulse — how to fish the Big Thump after dark and in dirty water, and what it simply won't do. - Source : https://carnafish.com/en/leurres/bizz-baits-big-thump-single-colorado-spinnerbaits/ - Language : en-US - Updated : 2026-09-08 ## Spec sheet - Brand : Bizz Baits - Model : Big Thump Single Colorado Spinnerbait - Type : Single Colorado blade spinnerbait - Target species : Bass, Pike - Size : overall length not stated by the manufacturer - Weight : not stated by the manufacturer - Running depth : surface down to roughly 3 m / 10 ft depending on sink time and speed - Retrieve speed : slow to very slow, just fast enough to feel the blade turning in the rod tip - Action : a single oversized Colorado blade turning wide and slow, throwing a low-frequency pulse a fish can home in on without seeing it - Rigging : snap or direct knot on the wire arm eye, factory-fitted 5/0 Mustad Ultra Point hook, soft trailer locked in place by the molded barb keeper - Colors : black and blue at night or in dark water, chartreuse and white in stained water by day, all black on a moonless night At night, a bass stops hunting with its eyes. It hunts with its lateral line, and what it picks up from a lure three metres away is not a colour but a wave. The Bizz Baits Big Thump is built around that single fact: one Colorado blade, deliberately oversized, turning slowly and pushing enough water to be located in total darkness. Everything else on the bait exists so it doesn't spoil that signal. ## Why one blade, and why such a big one A Colorado blade is round, wide, almost teardrop-shaped. It meets a lot of water resistance, so it turns slowly and far off the wire axis, and every revolution sends out a heavy, low-frequency pulse. That is the exact opposite of a willow blade, narrow and fast, which trades on flash rather than on displacement. Running a single blade instead of two concentrates all that resistance on one point. You feel it immediately through the rod: the Big Thump thumps, with a dull, regular beat you can count. Two blades would split the energy and produce a finer, choppier buzz — excellent in clear water by day, far less readable for a fish working on pressure sensors alone. That big blade comes with two consequences you have to accept. First, it brakes the bait: the Big Thump climbs in the water column the moment you speed up, so you slow down to keep it deep. Second, it costs casting distance, because it catches wind and air. This is not a long-range search bait, it's a lure for precise passes along a structure you've already identified. ## Night fishing, its real home The Big Thump earns its place as light fades and forage shoals push toward the margins. Bass hunting after dark sit on hard edges — rip-rap, dock pilings, sharp drop-offs, reed lines — structure they can follow without seeing it. Your lure has to swim within reach of those spots, not through open water. Cast parallel to the bank rather than straight out. A parallel cast keeps the bait in the productive band for the whole retrieve, where a perpendicular cast only crosses the feeding zone for a couple of metres. That rule applies to every spinnerbait, but it becomes decisive at night, when you can't correct your line of travel by sight. ### The rhythm that works Retrieve at the slowest speed that still lets you feel the blade turn. The moment the vibration drops out of the rod tip, you're too slow; the moment the bait climbs toward the surface, you're too fast. Between those two there's a narrow window, and the whole craft of night spinnerbaiting is staying inside it blind. One variation triggers a lot of bites: briefly stop reeling as the bait tracks past a structure. The blade stalls, the lure tips over and drops a foot or so, then starts again. That short break imitates prey losing its footing, and the strike usually comes in the second after you pick the retrieve back up. > At night, count your handle turns. When a bite comes, you know how many turns after the cast landed — so how far from the bank and how deep. Three fish later you've mapped the active layer without ever switching on your headlamp. ## Dirty water in daylight, the second job The same logic applies when your water body is coloured after heavy rain, a drawdown or a wind that has stirred the bottom. Twenty centimetres of visibility makes most subtle-swimming lures useless: the fish doesn't detect them early enough to commit. The Big Thump solves that with the sheer volume of water it moves. In that exact situation it's also a credible pike bait in Europe, on backwaters and silty pond tails in spring. Pike readily hunt by vibration in low-visibility water, and a single Colorado blade gives them precisely the signal they know how to follow. Run a wire or heavy fluorocarbon leader then: the single hook of a spinnerbait ends up deep in the jaw very quickly. ## Rigging, hook and hardware The Big Thump carries a 5/0 Mustad Ultra Point single hook, which places it squarely among the big spinnerbaits rather than the finesse models. The head is powder coated, with molded gill plates and oversized 3D eyes, and carries a molded barb keeper that holds a soft trailer without glue. The skirt is wire-tied rather than banded, so it won't spin around the head after a few fish. The wire arm plays a role people underrate: it's stiff enough to hold a big fish without deforming, yet flexible enough to transmit and amplify the blade's vibration. Too rigid and it would smother the signal, too soft and it would collapse onto the hook on the first fight. If it bends after a fish, straighten it by hand so the blade sits back in line with the hook, otherwise the bait tracks sideways. For the connection, a quick snap or a knot through the arm eye work equally well — unlike a lipped crankbait, a spinnerbait isn't hurt by a tight knot. Do plan on 30 to 40 lb class fluorocarbon or equivalent, though: night fishing happens in contact with hard structure and abrasion is constant. ### The classic mistake Fishing the Big Thump like a bladed jig, at speed and in open water. A big Colorado blade lifts the bait as soon as you accelerate, and it loses the point entirely: it ends up swimming a foot under the surface, well away from the fish. The other common mistake is skipping the trailer. A small shad or a twin-tail behind the skirt slows the fall further, widens the profile and steadies the bait — that's what the molded keeper is for. ## Colour by water and light - **Night, dark water**: black and blue, exactly the pattern in the photo. The silhouette reads against whatever light is left in the sky, and that is all you ask of a night colour. - **Stained water by day**: chartreuse and white, the classic pairing that stays visible in coloured water without looking artificial when clarity improves. - **Moonless night, very dark water**: all black, blade included. Counter-intuitive, but it gives the cleanest silhouette seen from below. ## Where it sits in the box The Big Thump doesn't replace an all-round daytime spinnerbait like the [Booyah Blade Double Willow](https://carnafish.com/en/leurres/booyah-blade-double-willow-spinnerbaits/), which trades on the flash of two willow blades and handles a fast retrieve. The two are complementary: one covers clear water, the other grinds along in the dark. Against a [Z-Man ChatterBait JackHammer](https://carnafish.com/en/leurres/zman-chatterbait-jackhammer/), the difference is frequency: the bladed jig vibrates fast and hard, the Big Thump thumps slow and low. If the first draws nothing in dirty water, try the second before you move spots. A [Booyah Covert Spinnerbait](https://carnafish.com/en/leurres/booyah-covert-spinnerbait/) fills the compact middle ground. Picking the right vibration is wasted if you miss the structure actually holding fish. That's exactly what [CarnaFish](https://carnafish.com/en/) makes easier: a photo of the spot, and the app suggests the zone to attack and a presentation suited to the day's conditions. To lay the groundwork before a first night session, our [beginner's guide to bass fishing](https://carnafish.com/en/blog/peche-black-bass-debutant/) covers the structure to read first. ## Key takeaways - A single oversized Colorado blade produces a low-frequency pulse a fish can locate without ever seeing the lure. - The retrieve has to stay slow: speed up and the bait climbs out of the productive layer. - A 5/0 Mustad Ultra Point hook and a molded keeper: this is a big bait, designed to carry a soft trailer. - Neither length nor weight is published by the manufacturer — check the retailer listing before ordering. ## FAQ ### Is the Big Thump only for night fishing? No, but that's where it makes the most sense. It also works well in daylight as soon as the water colours up and visibility drops below half a metre. In clear water under bright sun, a willow-bladed spinnerbait is the better call. ### How much does this spinnerbait weigh? The manufacturer publishes neither a weight chart nor a length for this model. Trust the retailer listing when you order rather than an estimate: an eighth of an ounce changes the running depth. ### Should I add a soft trailer? Strongly recommended. The head has a molded barb keeper designed to hold a soft plastic, which widens the profile, slows the fall and steadies the swim. A 3 to 4 in shad body is enough. ### Can you catch pike on this lure? Yes, in stained water across Europe it's a sound choice: pike follow a low-frequency vibration very well. Use a wire leader, as the single hook often ends up deep in the mouth. ### How fast should I retrieve it? At the slowest speed that still lets you feel the blade turning in the rod tip. Any faster and the bait climbs toward the surface and loses most of its point. ### My spinnerbait tracks sideways, what now? The wire arm has most likely bent during a fight or a snag. Straighten it by hand until the blade sits exactly in line with the hook: the wire is meant to be re-tuned. --- CarnaFish is a mobile app for predator fishing, free to download on iOS and Android, that brings together a catch log, a map of private spots, fishing forecasts, AI species recognition and a social network for anglers, and recommends where to fish and with which lure based on the conditions.
