4 Simple Steps To Seamless Wire Connections
1
Connect the Transmitter
Clip the transmitter to the circuit you want to trace. No special setup, no stripping wires, no piercing insulation.
2
Follow the Tone
Run the wand along the wire. The signal gets louder as you approach the fault. Follow the tone through insulation, behind panels, along the frame rail.
3
Pin the Exact Spot
The tone drops out precisely where the break, short, or bad ground is. Open just that section. Fix it.

Using a heat gun they provided and it was super easy to slip it on, twist the wires and slip it back on to solder and seal in one swoop is wicked cool! Very happy! Gave them
William
Verified Buyer
Work excellent! Seal AND solder wires together! I just hit them for about 15 seconds with my heat gun till shrink tube shrunk then solder melted to wire leads...boom, done!
Brad
Verified Buyer
This solder sleeve works exactly how it is described & kills two birds with one stone of soldering wire as well as sealing the connection. It is a huge time-saver.

Verified Buyer
After about 5 seconds the rubber material started to shrink. At about 9 seconds the solder started to melt & bond the wires. I gave the wires a firm tug & there were super tight.
