Shimano Metanium DC vs Antares DC is a comparison between two electronically controlled casting reels with different priorities. Metanium DC is the compact, lighter all-round platform built around a 34 mm spool and externally adjustable I-DC5. Antares DC uses a larger 37 mm spool, greater line capacity, and 4x8 DC control aimed at broader long-cast tuning.
The short answer: choose 24 Metanium DC when low weight, compact palming, short-to-long casting versatility, and fast external adjustment matter most. Choose 21 Antares DC when the larger spool, deeper line reserve, and dedicated extreme-distance mode better fit open-water casting.
34 mm Compact DC vs 37 mm Long-Cast DC
Metanium DC uses a 34 mm by 19 mm (1.34 by 0.75 in) MGL Spool III. The standard and high-speed models weigh 175 g (6.2 oz); XG models weigh 180 g (6.3 oz). Shimano positions the diameter as a balance between easy startup, low-trajectory short casts, and full-cast extension.
Antares DC uses a 37 mm by 19 mm (1.46 by 0.75 in) MGL Spool III. Standard and HG models weigh 220 g (7.8 oz), while XG models weigh 225 g (7.9 oz). The larger diameter retrieves more line at similar ratios and carries more nylon in every listed line class.

I-DC5 vs 4x8 DC
Metanium DC combines three line modes with five brake settings, giving 15 externally accessible combinations. Its firmware monitors spool-speed change and applies automatic braking around the selected line profile and setting. The control layout is designed for quick field changes without opening the side plate.

Antares DC provides four modes—fluorocarbon, braid, nylon, and extreme long cast—with eight external dial positions. That 4x8 layout offers a wider matrix and a mode specifically intended for maximum casting range. It also asks the user to make a more deliberate choice around line and casting goal.

Body, Gearing, and Feel Under Load
Both reels use magnesium Hagane bodies, MicroModule gearing, X-Ship pinion support, MGL Spool III, SilentTune, S3D machining, and corrosion-resistant SA-RB bearings. Metanium DC adds Shimano’s CoreSolid Body layout, integrating the level-wind protector with the metal frame to combine compact palming with rigidity.
Metanium DC uses a lightweight duralumin drive gear. Antares DC uses a high-strength brass drive gear. Material alone does not rank durability or smoothness because gear diameter, tooth geometry, support, lubrication, load, and service history also matter, but it helps explain the different mass and handling priorities.
Ratio and Retrieve Choices
Metanium DC spans 6.2:1, 7.1:1, and 8.1:1 ratios, retrieving 66, 76, or 86 cm (26.0, 29.9, or 33.9 in) per turn. Antares DC spans 5.6:1, 7.4:1, and 7.8:1, retrieving 65, 86, or 91 cm (25.6, 33.9, or 35.8 in).
The standard models are nearly identical in pickup despite their different ratios because of spool diameter. Antares HG matches Metanium XG at 86 cm (33.9 in), while Antares XG is the fastest option in this comparison.
Line Capacity
Metanium DC lists 12 lb at 100 m (109 yd), 14 lb at 90 m (98 yd), 16 lb at 80 m (87 yd), and 20 lb at 65 m (71 yd). That capacity suits a compact 70-size platform and avoids carrying unnecessary line on many bass and inshore casting setups.
Antares DC lists 12 lb at 130 m (142 yd), 14 lb at 110 m (120 yd), 16 lb at 100 m (109 yd), and 20 lb at 80 m (87 yd). The extra reserve better supports long casts, repeated reties, and heavier-line use. Actual fill changes with diameter, packing tension, and backing.
Which Reel Fits Your Casting?
-
Frequent short and medium casts: Metanium DC is 45–50 g (1.6–1.8 oz) lighter and easier to keep compact in hand.
-
Open-water maximum-range work: Antares DC combines a 37 mm spool, more capacity, and an extreme-distance brake mode.
-
Fast field adjustments: Metanium’s 15 externally accessible combinations keep the decision tree concise.
-
More brake combinations: Antares DC provides four modes and eight dial positions.
-
Highest pickup: Antares DC XG retrieves 91 cm (35.8 in) per turn.
-
Same listed drag: every model here lists 5 kg (11.0 lb), so drag does not separate the families.

What Specifications Cannot Decide
No brake system guarantees distance or prevents every overrun. Rod loading, lure aerodynamics, line type, spool fill, wind, casting stroke, dial setting, and thumb control remain decisive. A larger spool can preserve speed during a long cast, while a smaller spool can feel quicker in technical casting; neither is automatically better for every setup.
Bottom Line
Metanium DC is the better fit for anglers who want high-end DC control in a lighter, compact reel that moves easily between short, medium, and long casts. Antares DC is the more distance-focused system, with a larger spool, more line reserve, and a wider 4x8 brake matrix. Choose around casting environment and line volume, then select the ratio by retrieve speed rather than model hierarchy.
