TR45 OPERATIONS: Submerged unit with microcomputer, batteries, and replaceable link for timed release
Programmed pre-deployment underwater via electrical contact with programmer (TRP-45C)
Release accuracy: +/-2 minutes/month; after time's up, erosion-based release takes 10-20 mins (LK-40) or 15-30 mins (LK-80)
Ocean/bay water effective due to electrolytic erosion, not suitable for freshwater
Release triggered by erosion, various link options, up to 170-day release, 0-600 ft depth, 4-year battery life
TR45 POPUP: Submerged release unit with microcomputer, batteries, and replaceable link
Programmed underwater via electrical contact with programmer (TRP-45C)
Accurate release timing (+/-2 minutes/month), erosion-based release process
Suited for ocean/bay water, integrated float/line spool, selectable line length, up to 170-day release time, 0-60 ft depth, 4-year battery life
TR4RT: Innovative ropeless fishing for single-trap, near-shore fisheries up to 500 ft depth
