The GTR can efficiently be used for float and bait release for both shallow and deep water trapping.
Float release for shallow water trapping
By making a loop in your trap line and attaching the GTR across the mouth of the loop, the line is shortened and the float pulled beneath the surface of the sea. After a predetermined duration, the GTR will corrode through… the loop releases and the float will pop to the surface.
Float release for deep water trapping
A basket is used to contain the floats and rope to prevent the rope from fouling as it unravels. When the GTR releases, the markers and rope will shoot to the surface at the predetermined time.
Some floats are compressible and will lose their flotation if pulled too deep underwater. Low density foam floats should therefore not be used in deep water.
When a float is placed underwater it will lighten the trap by a few kilograms. Extra weights on the traps may be necessary when using GTR technology.
Bait release
Recent investigations indicate a need to conserve bait between the time of baiting a trap to nightfall when fish and crays commence feeding. The release of a fresh bait 8 to 10 hours after the trap is set, to present an attractive bait at prime feeding times, is a simple arrangement using the appropriate GTR.
Alternatively, if you are trapping over a longer period, for example 2 weeks, the release of a second fresh bait from a canister using the appropriate GTR may increase the yield from each trap.
