We had Leadcore Line and we added new functions recently to it, but we never had Copper Line. In Dipsy Troller, Version 3, assuming you want to have all solutions at your fingertips, we decided to add the two most used Copper lines 30# and 45#.
Also, these lines are not as abrasion resistant as steel wires nor their surface is hard as steel wires – don’t go shark fishing with copper fishing lines – they are harder than nylon mono lines, but … Also, kink resistance of copper wires could be better 🙂
Due to copper’s density of 8.96g/cm3, copper fishing lines sink much more than ordinary lines – for example, Blood Run Tackle Copper Fishing Line dive depths are around:
– 20 pound copper fishing line – 8 feet of depth for every 50 feet of line released at 2.5 mph (2.43m of depth for every 15.3m of line released at 4km/h or 2.2 knots),
– 32 pound copper fishing line – 8 feet of depth for every 50 feet of line released at 2.5 mph,
– 45 pound copper fishing line – 9 (2.75m) feet of depth for every 50 feet of line released at 2.5 mph,
– 60 pound copper fishing line – 11 (3.35m) feet of depth for every 50 feet of line released at 2.5 mph.
blood-run-tackle-copper-fishing-line-1mThese values are for buoyancy neutral lures.
Of course, actual lure or bait depth depends on many factors like:
– speed and direction of underwater currents,
– lure and bait buoyancy and drag resistance,
– trolling speed,
etc.
Recommended usage: use copper fishing line as the main line and good fluoro line as the line leader – few feet (not more than 20 feet) is more than enough. Leader line length, of course, depends on fishing depth, trolling speed, how clear is the water, daylight conditions etc.
