1. A device for collecting a sample of one or more substrates, comprising:
a collection tube having a first end and a second end;
a cap pivotable about the first end;
a footplate pivotable about the second end;
a releasable fastener, the releasable fastener configured to releasably attach to the cap and the footplate;
a pole configured to be controlled by a user of the device for submerging the collection tube into the one or more substrates and for raising the collection tube;
a trigger line coupled to the releasable fastener and configured to be pulled by the user of the device independent of the user controlling the pole to submerge and raise the collection tube;
a trigger line guide configured to position the trigger line to activate the releasable fastener;
wherein the cap and the footplate are configured to be biased closed so that a watertight compartment is established inside the collection tube when the cap and the footplate are closed; and
wherein the cap and the footplate are releasably attached to the releasable fastener while the cap and the footplate are forced open, and further wherein the trigger line guide allows for a force which is applied to the trigger line to transfer to a component of the releasable fastener, so that the cap and the footplate are released into respective closed positions.
