Sorry, but what is a stackable crab trap.
All crab pots can be stacked, because they are cubes.
A picture will help?
It is a 5 sided hand trap that the top is open and they will stack inside of each other like five gallon buckets. That take up a lot less room on a boat.
So how the hell do you catch crabs with an open top?
Tacklebox sells Foxymates. They are mass produced, but very good. Expect to modify the bait holder to your liking - the Springs are useless. Crabs can grab the bait right out of it.
So, shouldn't your forum name be "Crab Bait" ?
To be most accurate, it would have to be "Crow/Crab/Fish/Deer/Goose/etc. Bait".
