I got this for our boat and it fits nice. The handle has a nut on it that you twist to unlock and extend.Twist back the other direction to lock in place. You have 2 net heads to pick from. . The net is little over a foot deep The triangle has almost a 16 inch diameter and the circle is just over 15” in diameter.They both collaps down for easy storage . And once extended you just screw it to the end of the handle and it holds everything in place. #RankBoosterReview #Sponsored #Lureshine https://www.amazon.com/Lureshine-Collapsible-Lightweight-Telescoping-Alternative/dp/B074PKHT3D
