This is a battery-powered electric knotter used for connecting PE lines and shock leaders. It is especially recommended for those who find it difficult to tie PE lines and leaders, those who find it time-consuming and troublesome, and those who tend to have variations in the knot strength. It allows for easy and consistent knotting in a short amount of time! In the past, nylon was the main fishing line, with few other options, but in recent years, more and more people are using PE lines, which are sensitive, strong, and thin. It seems that PE lines are used in many fishing situations, from lures to bait fishing, such as for sea bass, amberjack and other blue-water fish, rockfish, bass, trout in streams and managed fishing areas, and for ajing and mebaring. It is recommended for beginners and those who have never used PE lines even if they have been fishing for a long time. For those who have been recommended PE lines by shop staff or people around them and want to try them, but have given up on PE lines because they find it difficult to connect them to leaders! It allows you to easily and quickly create a line system with FG knot strength, and it supports everything from light games to offshore jigging. 【Product Specifications】 Body size: Length 11cm Width 6cm Thickness 2cm Product weight: 86 g Compatible lines: PE line: 0.6 to 3 Nylon, Fluorocarbon line: 1.5 to 12 Compatible leader: 6 to 40lb *Power supply: Uses 2 AAA batteries (sold separately) 【Product Contents】 Line tying machine body Spool clip Instruction manual (not in Japanese) Even if you don't understand the language of the instruction manual, there are many videos explaining how to use it, so search for "line tying machine" or "line twister" on YouTube, etc. ⚠To reduce shipping costs and sell at a lower price, the main unit will be taken out of its original box, wrapped in cushioning material, and placed in a Yu-Packet Post mini envelope for shipping.
