The DSR (Draw String Retention) system is an innovative, short term solution to retaining your catch safely straight after landing. Simply net your fish, slide the toggle up the integrated draw string until it pulls the net closed and your finished. Now you have time to get your camera and scales ready without fear of the fish escaping the net or having to stress the fish out by moving it to a seperate sack retainer. The Defender Nets are great value 42" nets with optional 1 or 2 piece carbon composite handles and perfectly placed rubber shrink grips.
