# Megabass Deep-X 300: three metres from a very small body > How a compact crankbait reaches 3 to 4 m, why its tight vibration gets past educated fish, and how to fish it in contact with the bottom without snagging. - Source : https://carnafish.com/en/leurres/megabass-deep-x-300/ - Language : en-US - Updated : 2026-09-26 ## Spec sheet - Brand : Megabass - Model : Deep-X 300 - Type : Compact deep diving crankbait - Target species : Bass, Zander - Size : around 7 cm - Weight : in the region of 18 to 21 g - Running depth : 3 to 4 m depending on line and casting distance - Retrieve speed : medium and constant, no twitching - Action : tight high-frequency roll, sharp deflection off obstacles - Rigging : straight to 0.20-0.25 mm fluorocarbon, rod with a progressive action - Colors : natural and ghost patterns in clear water, dark back or chartreuse as soon as visibility drops On a heavily fished water, the fish in the three-to-four-metre band have seen the same thing all season: a big American crankbait, wide body, broad roll, ten centimetres of silhouette. It is an excellent lure, and that is precisely the problem — it is no longer a surprise to anyone. The usual alternative is to drop into finesse, therefore soft plastics, therefore slow. You go from searching to point-by-point fishing, and you lose the ability to cover a whole plateau in an hour. The Deep-X 300 fills the missing slot: seven centimetres of body, three to four metres of running depth, and a vibration nothing like that of the big divers. You keep the crankbait's searching speed with a signal those fish have not heard. ## The depth-to-volume ratio Making a crankbait dive to four metres is easy: all it takes is a big lip and a big body to carry it. That is why deep crankbaits are almost all bulky — body size is not an aesthetic choice, it is a mechanical consequence. Getting to the same depth with a seven-centimetre body means compensating elsewhere: a long, narrow lip rather than a wide one, a high body density, and very precise balance so the whole thing does not spin out under the pull. That is exactly what this model does. Three practical consequences: - **You present a 7 cm silhouette at 3.5 m**, which barely exists anywhere else in the box. - **The resistance on the retrieve is much lower** than that of a big deep crank. You fish longer without wearing yourself out, on lighter tackle. - **The zone of influence is narrower**: the lure attracts from less distance. You have to pass close to the fish, so you need to read the plateau properly. ## Tight vibration, not a wide roll A big deep crankbait produces a wide, low-frequency roll: a heavy vibration that carries far, perfect in stained water or to call scattered fish. The Deep-X 300 does the opposite, with a short, fast movement closer to a shiver than a sway. That high-frequency signal has two specific advantages. **It looks more like a stressed baitfish than an object cutting through the water**, which counts in clear water. And above all, **it is not in the repertoire of lures the fish in that zone are used to refusing.** On a water where the big crank is the norm, changing frequency is often worth more than changing colour or depth. On zander, this point is decisive. A zander sitting on a three-metre plateau reacts very well to a lure that passes fast and vibrates tightly right next to it, where a big roll tends to lift it off without committing it. ## The retrieve: look for contact 1. **Cast long.** The depth reached depends directly on the length of the retrieve: on a short cast, you do not have the distance to get down. 2. **Rod low, tip towards the water or even in it** if you want the last few centimetres. 3. **Retrieve steadily, with no twitching**, until you feel the first contact with the bottom or an obstacle. 4. **On contact, keep turning without speeding up.** The lure will deflect violently to the side: that deflection is the main trigger, not the steady swim. 5. **After a clean deflection, pause for a second.** The lure floats and rises slightly, often unhooking itself from the obstacle — and that is almost always when the bite comes. > On the water: if you are not touching anything with a deep crankbait, it is almost never because it is too deep. It is because it is not touching anything. A crankbait that travels through three metres of open water without ever hitting the bottom, a stump or a rock only catches active fish. Choose a lure depth slightly greater than the bottom you are fishing, and accept that you will scrape. ## Actually reaching the stated depth | Parameter | Effect | Advice | |---|---|---| | 0.20 mm fluorocarbon | Maximum depth | Open zones, clear water | | 0.30 mm fluorocarbon | 40 to 60 cm shallower | Snaggy zones, safety margin | | 40 m cast | Nominal depth reached | Reference setting | | 15 m cast | About 1 m less | Margin fishing, no interest here | | Rod held high | 30 to 50 cm shallower | To be avoided, except to clear an obstacle | Line diameter is the most effective and most often overlooked parameter: going from 0.30 to 0.20 mm gains more depth than any amount of speed correction. ## The tackle it does not demand This is one of its real arguments. A big deep crankbait forces you onto a long, powerful rod and an exhausting retrieve. The Deep-X 300 pulls far less. A rod of 2 m to 2.10 m, medium power, progressive action, is plenty. The progressive action matters more than the power: with trebles and a fish fighting at three metres, a rod that is too stiff loses fish. A medium-ratio reel, around 6, helps you hold a constant speed without forcing it. ## Against the big deep crankbaits The [Strike King 5XD](https://carnafish.com/en/leurres/strike-king-5xd/) covers the same depth band with a far bulkier body, a wide roll and a signal that carries. In stained water, on scattered fish or when you need to find them fast, it is still ahead: it calls, the Deep-X 300 does not. The [Strike King 10XD](https://carnafish.com/en/leurres/strike-king-10xd/) plays somewhere else again, at six or seven metres, in a band the Deep-X does not claim to reach. So the question to ask yourself is simple: are you trying to find fish, or to persuade one you have already located and which is refusing? In the first case, take the big crank. In the second, a seven-centimetre body vibrating tightly at three and a half metres is a proposition very few anglers make on these waters. Our [beginner's guide to zander fishing with lures](https://carnafish.com/en/blog/peche-sandre-leurre-debutant/) explains how to find these plateaus. And if you are unsure which crankbait depth to tie on in front of an unknown zone, [CarnaFish](https://carnafish.com/en/) analyses a photo of the spot and answers. ## Key takeaways - 7 cm of body for 3 to 4 m of depth: a rare combination, outside the usual repertoire. - Tight, high-frequency vibration instead of the wide roll of big deep cranks. - Deflection off the bottom or an obstacle is what triggers, not the steady swim. Look for contact. - Line diameter sets the depth more effectively than speed; 0.20 mm to get down as far as possible. - It does not call from a distance: it is a lure to convince, not to find. ## FAQ ### How deep does the Deep-X 300 really run? Between 3 and 4 m on a long cast with fine fluorocarbon. On a short cast or with 0.30 mm line, count on 50 cm to 1 m less. A crankbait's depth depends as much on the length of the retrieve as on the lip. ### Why choose a compact crankbait over a big one? For the signal. A small body vibrating tightly at three metres presents a silhouette and a frequency that fish on busy waters are not used to seeing, whereas the big wide-rolling crankbait is used there all year. ### Does it work on zander? Yes, on plateaus and drop-offs between two and four metres. Zander respond well to a fast, vibrating pass right next to them, provided the lure touches bottom regularly. ### What line should I use? Fluorocarbon of 0.20 to 0.25 mm. The 0.20 gets you to maximum depth, the 0.25 gives a safety margin in snaggy zones. Avoid braid straight through, which makes the hookset too violent on trebles. ### Do I need a dedicated crankbait rod? Not essential with this model, unlike the big divers. A rod of around 2 m, medium, with a progressive action does the job: the progressive action stops you losing fish hooked on trebles at three metres. ### What if it snags too often? Go up a line diameter to lift it a few tens of centimetres, and raise the rod slightly as you approach the cluttered zone. On contact with an obstacle, do not pull: give it a second of slack and the lure floats up and usually frees itself. --- 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.
