The Plano 3730 tackle box is the big brother of the standard Plano 3700 tackle box. The 3730 is 50% deeper and will divide into as many sections but give you more storage options because it is deeper. Use the 3730 for oversized swimbaits and crankbaits, for storing LOTS of soft plastic, or for a toolbox for on the water repairs. This box features the Pro Latch, which means the latch is not molded with the box so it won't break off like the original design. The Plano 3730 tackle box will fit in the footprint of the 3700 box and will fit most soft-sided tackle bags designed for the 3700. If you've got BIG stuff to carry around, get the big box.
