A 125 mm Troll float is used as a subsurface float

Lift by the rope only and keep vertical
Rest the trap on the side of the boat on the bottom plate
Puncture the parcel-tape patch to spill excess water
If sediment above the patch, catch the water and sediment in the 5-litre jug and transfer to a 2-litre bottle and label

The bottom trap will have more sediment than the top !
Traps @ 1, 2, 6, and 7 are likely to have large amounts of sediment
There are 2 traps at the top and two at the bottom = 4 traps per line
= total of 40 traps
