The Squall Binder 3700 Tackle Bag / Bait Binder Combo is a new level of flexibility and utility. We have beefed up the size of our 3700 tackle bag and added a built-in tackle binder to the top. The bag comes with four 3700-size trays and a tackle binder loaded with pages for all of your tackle. Instead of carrying two bags with you, now you can combine all of your tackle needs into one.
