Nytt isfiskekonsept. Mormyskafiske med attraktor. Blinken er laget av plast og er vektløs i vann. Forsiktig fisk kan dermed dra avgårde med kroken uten å merke motstand. Blinken festes til snøret med duppstoppere og kan flyttes opp og ned på snøret etter behov.

Blinken kan også brukes som attraktor på ulike måter ved sommerfiske. Read more
