# Berkley Lab Series Minnow: the layered soft bait built for strolling > A coating that turns to slime, an internal air chamber, a forked tail — what the Lab Series Minnow actually does and how to rig it on forward-facing sonar. - Source : https://carnafish.com/en/leurres/berkley-lab-series-minnow/ - Language : en-US - Updated : 2026-09-23 ## Spec sheet - Brand : Berkley - Model : Lab Series Minnow - Type : Forked tail soft minnow (soft jerkbait) - Target species : Bass, Zander - Size : not published by the manufacturer in its product description - Weight : not published by the manufacturer — the bait is sold bare, so the weight comes from your head - Running depth : mid-water, with depth set by the weight you add and your speed - Retrieve speed : slow to medium, trolled slowly behind the boat or on a steady straight retrieve - Action : a natural body roll plus a fast quiver of the forked tail, posture held by an internal air chamber - Rigging : a light weighted hook nose-rigged for strolling, or a fine jighead; a thin-wire Texas hook over clean bottom - Colors : translucent chartreuse-green heavy with gold and silver flake in clear to lightly stained water, pearl white in cold water, a dark tone in low light February, water at seven degrees, fish sitting mid-column over a hole and refusing anything that moves fast. You drop a small soft bait to their level, move at walking pace, and watch the arch rise towards it on the screen. That style of fishing — the very slow troll, strolling — asks for a very specific soft bait: light enough to hang in the column, stable enough never to tip over, scented enough to convince a fish with all the time in the world to think it over. That is precisely the brief behind the Lab Series Minnow. ## A bait poured in layers, and what that means Berkley does not pour this bait from a single material. It is made in small batches, in successive layers, each with its own job. At the core, a PowerBait taste layer — the one that makes a fish hold on a second longer. Over that, a MaxScent layer whose role is to extend scent release over time. On the outside, a powder coating that converts to slime the moment it hits water. That coating is the real novelty. On the splashdown it releases a concentrated burst of scent — Berkley quotes twenty to thirty minutes of active dispersal — and once that film has gone, the MaxScent and PowerBait layers beneath take over for the rest of the bait's life. In other words: a peak of attraction up front, then a quieter but lasting upkeep. That behaviour has a practical consequence worth keeping in mind. Leave the bait sitting in the water for ten minutes without working it, then pull it out, and you have spent part of your peak without using it. The Lab Series Minnow gets rigged just before you fish the zone, not half an hour earlier. ## The internal air chamber, the detail that holds posture The body carries an air chamber that keeps the bait on an even keel through the retrieve. That is not a gimmick: a long, slim soft bait has an unfortunate habit of rolling onto its side or flipping onto its back as soon as the weight is not perfectly centred, and a bait that fishes crooked triggers nothing. Here the localised buoyancy offsets that flaw and steadies the profile. The result in the water is a slow roll of the body on its axis combined with a fast quiver of the forked tail — two signals running at different speeds, which give the bait a credible life even at a crawl. A [Zman Scented Jerk ShadZ](https://carnafish.com/en/leurres/zman-scented-jerk-shadz/) chases the same thing by another route: the Zman holds its shape through the stiffness of its elastomer, the Berkley through internal buoyancy. ## Strolling, the technique it was drawn for Berkley presents this bait as particularly suited to strolling with forward-facing sonar — a very slow troll where you follow the bait on screen and adjust its depth in real time. It is a style that spread fast and that demands precise tackle. ### Nose rig A light weighted hook, nose-hooked, point exposed. This is the rig that leaves body and tail the most freedom. The bait tracks straight behind the line without forcing, and every micro-acceleration of the boat turns into a tail beat. It is also the rig that hooks best on a fish inhaling from behind. ### Fine jighead For a more vertical presentation, or on a straight retrieve from the bank, a slim 2 to 7 g jighead gives better depth control. Pick a head whose collar does not crush the body: the outer coating marks easily, and a deformed body loses its keel. ### The classic mistake Fishing it too fast. Past a certain speed the forked tail vibrates so hard it saturates the signal, the body stops rolling and you are left with a generic soft bait. It peaks somewhere between the pace of a slow current and that of an electric-motor troll — which is to say slower than your instinct suggests. > Keep the clamshell. Berkley lays these baits flat, one by one, precisely so they do not bend or take on moisture — and it is justified: a Lab Series Minnow stored folded in a bag keeps the crease and will never swim straight again. An opened bait goes back in its slot, not loose in the box. ## The dimensions the manufacturer does not give Let us be plain: the technical description for this bait publishes neither length nor weight, unlike most of the brand's hard baits. We know it is a slim, elongated baitfish profile with a forked tail, offered in several references, but exact dimensions are not stated in the available documentation. If size is a deciding factor for your use, check it on the packaging rather than trusting an approximate figure. ## Colours by water - **Clear to lightly stained water**: the tone in the photo, a translucent chartreuse-green heavy with gold and silver flake, working through light refraction rather than solid colour. - **Cold water and grey skies**: pearl white, readable without aggressive contrast, matching the time of year when the forage fish itself is pale. - **Dirty water or low light**: a dark tone, for a clean silhouette against the light when flake no longer does anything. ## A specialist's bait, not a Swiss army knife The Lab Series Minnow is a slow, controlled-presentation bait. It does not replace a paddle tail when you need to cover water fast, nor a [YUM Money Minnow](https://carnafish.com/en/leurres/yum-money-minnow/) when you need more bulk for a big fish. Its ground is the visible, suspended fish that refuses everything else — and in that precise role, the stack of scented layers makes a real difference to how long the fish holds on. You still have to know where those suspended fish sit, which is rarely obvious from the bank. That is the kind of reading [CarnaFish](https://carnafish.com/en/) simplifies: a photo of the spot, and the AI suggests a zone, a depth and a presentation suited to conditions. And to build the box around it without spending a salary, our [budget predator tackle guide](https://carnafish.com/en/blog/materiel-peche-carnassier-budget/) lays out the trade-offs. ## What to remember - Three stacked layers: PowerBait taste at the core, MaxScent for duration, an outer coating that becomes slime and disperses hard for twenty to thirty minutes. - An internal air chamber holds the bait's keel, letting it roll cleanly instead of tipping over. - Designed for strolling on forward-facing sonar: it peaks at very slow speed and saturates if you speed up. - Neither length nor weight published by the manufacturer — check the size on the packaging before buying. ## FAQ ### What exactly does the outer coating do? It is a powder that converts to slime on contact with water and immediately releases a concentrated burst of scent, active for twenty to thirty minutes according to Berkley. Once it has dissipated, the MaxScent and PowerBait layers underneath take over for the life of the bait. ### How long is the Lab Series Minnow? The manufacturer publishes no length in its technical description. It is a slim, elongated baitfish profile with a forked tail, offered in several references: the exact figure is on the packaging, and checking beats estimating. ### Do I need forward-facing sonar to use it? No, but that is the use Berkley advertises and where it performs best. Without sonar it remains excellent on a slow straight retrieve over a breakline or along a weed edge, provided you keep the pace moderate. ### Why keep it in the clamshell? Because it is packed flat, one by one, so it neither bends nor absorbs moisture. A bait stored folded in a bag keeps the crease and no longer tracks straight. Put it back in its slot between sessions. ### Does it stand up to repeated bites? It is a layered soft bait, so it marks and tears faster than an elastomer. Count on one bait for a few fish, and check the keel after every bite: a body that has slipped on the head fishes crooked before it is even damaged. ### Can it be fished Texas rigged? Yes, over clean bottom, with a thin-wire hook so you do not crush the body. But the weighted nose rig stays the most consistent with what this bait does: it leaves the forked tail free, and that tail is most of its signal. --- 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.
