Particular embodiments comprise: a buoyant main body having an axial channel with corresponding end surface openings; an retention member seat (e.g., groove, ridge, etc.) running around the main body surface; and at least one line retention member receivable and retainable by the seat, and operative with the seat to retain a line passing therebetween at two points. The retention member is displaceable from the seat by sufficient line tension, thereby disengaging the slidable strike indicator. Particular embodiments comprise two strike indicator stop members attachable at user-selectable line positions, and operative to delimit a slidable range of a disengaged slidable strike indicator. Novel methods for fishing, with a slidable reversibly detachable indicator, at a depth greater than the length of a fishing rod are presented. ## Claims ### Claim 1 A reversibly disengagable strike indicator, comprising: a buoyant main body portion having an exterior surface, first and second main body ends, and an axial closed-walled channel therebetween, the channel having a first end opening at the first main body end and a second end opening at the second main body end, the channel, sufficient, in operation, to allow slidable passage of a fishing line therethrough without permitting the line to separate from the main body;
