Nash Slap Head Indicators feature an integrated, self tensioning line gate. The smooth rounded head ensures snag-free operation. These Slap Head Indicators are manufactured from solid PTFE. The body of the indicator screws apart to expose 4 isotope slots (so the indicator can be seen at night from any angle). Available in 6grm (FC-SLAP-6), 9grm (FC-SLAP-9), 12grm (FC-SLAP-12) & 18grm (FC-SLAP-18).
