Depuis la première version, l’app permettait de faire les calculs pour la ligne plombée, mais nous n’avions jamais ajouté la possibilité de faire les calculs pour la ligne de cuivre. La démarche actuelle étant de proposer la plus grande diversité de plongeurs possible, nous avons ajouté les deux lignes les plus courantes 30 livres et 45 livres.
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.
These 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.
