A maniacally well-knotted knot does not weaken the resistance of the thread on the junctions, the problem is that sometimes unfortunately not all knots are well made .... You think that to make a fishing trip sometimes you make hundreds of kilometers and then still many miles of navigation to reach the ideal spots, you spend thousands of euros in sophisticated equipment such as echo sounders, reels, fishing rods and expensive small parts of all kinds, without thinking about the cost of the boat and the fuel needed, then in the most nice .... Our thread gives way to a knot hurt and maybe that was the only fish that has taken us all day!
Of course it is also useful for testing the shock leader in surfcasting, I have any other knots or junctions, in addition testing the actual breaking load of the line and its relative elasticity.
The thread is wound a few turns around these 2 rings, made of soft material and it is not stressed. I have damaged it, the test is done to recover its shape.
TEST NODO WIND ON
AT THE MOMENT THE ELECTRONIC BALANCE IS EXCLUDED TO BE SUPPLIED SEPARATELY WITH OVERPRINT TO AGREE, EVEN BECAUSE MANY OF YOU ALREADY POSSESS IT.
This is the link of the mounted scale with capacity up to 300 Lbs
These others also have the PEAK function, ie they automatically store the maximum value detected, comfortable but not essential for testing the mechanical resistance of the wires before they are stuck.
One that weighs up to 150 KG. and another up to 50 Kg. with a resolution of 50 grams.
It is made of aluminum, naylon and stainless steel, the sliding couplings are in hardened steel and ball recirculating guides that do not make any friction, 100% reliability of the measurement.
