Does anyone weigh down their doors of metal cage traps, keep them from swaying open in current, if so how much weight?
Cheers

I weight down each of mine just to make sure no movement from a light current.

Thanks sea shark, how much weight do you attach?

I put about 2oz of lead on the danielson doors, but the promars I do not use any weight.

Thanks for the info
Im going to hit up hmb this week.
After I drop the pots I'm going to try some sand dab and sardine fishing?! I saw some big schools of bait the other day out there.
happy new year

No weights on the doors (yet) but I use 3 pieces of rebar wired to the bottom of the cage for weight.

I put about 2# and I do have the weighted doors for my Danialson trap.

I put about 2oz of lead on the danielson doors, but the promars I do not use any weight.

ditto....few wraps of pencil lead on each door works great
