What owners report

Most praised
  • Owners say crankbaits come out of a damp boat locker looking the way they went in, hooks included
  • The clear lid gets credit for ending the habit of opening three boxes to find one lure
  • Anglers who label their boxes say the label slot finally makes a full stack readable from the side
Common complaints
  • Some owners find the lid seal stiff to close until the O-ring settles after a few trips
  • Tall lures that fit a plain deep box do not always fit this standard depth, which surprises buyers who skipped the depth check
  • A few owners wish the box came with more dividers for very small terminal tackle

What owners report

Most praised
  • Owners say the extra depth finally lets them close the lid over taller crankbaits without forcing it
  • Bag anglers like that the 3600 size leaves room in the bag for a second box and a spool of line
  • The latch gets mentioned by owners whose old boxes popped open in transit
Common complaints
  • Some owners buy it expecting 3700 capacity and find the smaller footprint limiting
  • A few report small hooks migrating under dividers when the box rides loose in a bag
  • Owners who fish in heavy rain note this is not the sealed box for an open deck

Our recommendation

Buy the EDGE 3700 Standard if your lures are worth protecting from damp and spray, and your bag or locker takes 3700 boxes. Buy the 3600 Deep if you run a 3600 bag system, need depth for taller lures, and want a capable box for far less money. The EDGE is the better box; the 3600 Deep is the better buy for a 3600 system, because a great 3700 box that does not fit the bag is no use at all.

Seal and rust protection

This is the real gap. The EDGE seals with a Dri-Loc O-ring, guards rust with Rustrictor in the base, and manages trapped moisture with a WaterWick divider. The 3600 Deep latches firmly with ProLatch, but it is not a sealed box and it has no built in rust system. On a wet boat deck, the EDGE protects tackle that the 3600 Deep merely contains.

Size and system fit

The EDGE is a 3700 box at 14 by 9 inches, while the 3600 Deep is smaller at 11 by 7.25 inches, but deeper at 2.75 inches against the EDGE standard depth of 1.88 inches. That means the smaller box actually fits some taller lures the standard EDGE cannot close over, while the EDGE holds a wider spread in one layer. System fit decides this one: buy the size your bag takes, then choose depth within it.

Price and role

The 3600 Deep is a budget box that can be bought several at a time for a full spread. The EDGE is a premium box bought for the lures that matter most. Many anglers end up with both ideas in one system: EDGE boxes for expensive hard baits, and cheaper deep boxes for terminal tackle and everyday lures.

Choose Plano EDGE 3700 Standard Utility Box if…

  • Your bag, rack or locker takes 3700 boxes
  • Your lures are expensive hard baits stored in damp places
  • You want a sealed box with rust protection built in

Choose Plano ProLatch 3600 Deep StowAway if…

  • Your system is built around 3600 trays
  • You need depth for taller lures at a budget price
  • You want several boxes for a full spread without a premium bill

Questions, answered

Can I mix 3700 and 3600 boxes in one bag?

Only if the bag has slots or space for both sizes. Most bags are built for one tray family, so a mixed set leaves gaps or crowding. Pick one family for the bag, and use the other size only where it has its own home.

Which box is better for a boat locker?

The EDGE, because a boat locker is damp, and the seal plus Rustrictor protection directly address that. The 3600 Deep suits a bag that lives indoors and travels to the boat for the day.
