UltraFire® C15S 365nm UV Blood Tracking Light

ZWB2 Filtered 365nm UV | Blood Trail Tracking | USB-C Rechargeable
After the shot, the hard part begins. The UltraFire® C15S pairs a 365nm UV source with a ZWB2 filter that blocks much of the visible violet light, keeping the beam clean so blood drops show up darker and higher in contrast against leaves, grass and soil.

Simulation for illustration. Real results vary with terrain, how old the blood is, and ambient light.

Why the trail looks clearer

  • Less purple glare

    Standard 395nm lights throw visible purple light that washes out the ground. The ZWB2 filter on the C15S blocks it, so the blood stands out and you aren't squinting through a purple haze.

  • More ground in every sweep

    A 16W 365nm emitter lights a wider patch at once. You cover more leaves per pass and miss fewer drops.

  • Reach without crowding

    A deep reflector throws the beam out ahead, so you can scan from a safe distance instead of hovering over every leaf.

  • Steady through a long search

    Constant-current delivery holds output steady, so the light you have at the end of the night is the one you started with.

Wherever the trail goes

  • Timber and leaf litter

    Blood on oak leaves and duff is easy to walk past. Sweep low and the marks stand out against the ground.

  • Creek banks and rocks

    Wet rock and gravel hide drops and smears. Check the boulders, logs, and banks the animal brushed past.

  • Field edges and stubble

    Follow the trail out of cover and along the edge, where drops thin out and get easy to lose.

  • After dark

    Most recoveries run past sundown. Use the C15S to find the sign and your white light to walk the line.

Working a blood trail with the C15S

  1. Start at the last sign

    Go back to the last blood you're sure of, or to where the animal stood when you shot, and begin there.

  2. Sweep low and wide

    Hold the light low and sweep side to side, working ahead of the last mark in the direction the animal ran.

  3. Mark every drop

    Flag or tape each spot. The line of marks shows where the animal is headed and gives you a place to back up to.

  4. Switch lights to move

    When you know the direction, use your white light to walk the line. Go back to the C15S when the drops get sparse.
