Balzer Matze Koch UV Booster Crankbait 5cm 0.4m 4g Fire Fly

Balzer Matze Koch UV Booster Crankbait 5cm / 4g — Shallow-Water Predator Trigger in Fire Fly

A compact crankbait (hard-bodied wobbler) built for active spinning on trout, perch, and other predators in streams, ponds, and stocked trout lakes — now with a UV-active finish that adds an extra edge when light is low or water is coloured.

UV-Active Finish for More Reaction Strikes

The lure's UV-reactive coating absorbs and re-emits ultraviolet light, making the Fire Fly colour pop even in overcast conditions, at dusk, or in slightly murky water. Predators that might ignore a standard lure will often zero in on that added visual signal, turning followers into biters.

0.4 m Running Depth — Built for Shallow Zones

At 5 cm and 4 g, this crankbait runs at just 0.4 m depth, letting you work the top layer of the water column where trout and perch frequently feed. It's ideal for sweeping shallow bays, stream runs over gravel bars, and the margins of stocked lakes without constantly snagging the bottom.

Choose the Right Variant

Every variant shares the same 5 cm body, 4 g weight, and 0.4 m running depth. Colour is the only difference, so pick based on water clarity, light conditions, and target species:

• Fire Fly — UV-active warm glow; effective at dusk, dawn, and in stained water; trout & perch

• Blue Melon — cool blue-melon contrast; clear-water trout in bright conditions

• Blue Arctic — subdued cool tone; clear, cold streams and mountain lakes

• Green Fire Tiger — high-contrast tiger stripes in green; aggressive perch and stocked trout

• Orange Fire Tiger — warm high-contrast tiger stripes; perch and pike in coloured water

• Lime — bright chartreuse; low-visibility water, cloudy days

• Albino — pale, natural finish; clear water, pressured fish

• Night Crawler — dark, worm-inspired pattern; shaded streams, evening sessions

• Pike — larger predator-trigger colouring; when pike are present alongside trout

• Hot Spot — intense accent colours; coloured or deep-tinted water
