Abstract: Abstract The fishing-rod holder as per drawings and specifications, is the ultimate in utility from both a standpoint of user ease and immediacy of operation.  No other sports fishing-rod holder attempts to fix rod and reel in an immediately operable position.  This holder has virtually eliminated the need for muscle in deeper fishing practices employing increasing weights.  The unique application of tube (A1 & A2) locked on the rod, permits, co-operatively with B1, the complete restraint of the rod and reel.  Optimum utility is achieved.  The fish can even be 'played' while rod is still in holder (a boon to many a handicapped fishermen).  It can be seen this method enhances the operator's control actions during emergencies.  It also extends the operator's real capacity to use more than one rod.
