They help a bunch...nice to hold an object with both hands while looking at it..
Great pin pointer from Garrett and Metal Detecting Stuff is my #1 source for products. Excellent service
If you are afraid of hooking up your motor or ESC backwards after installing black (or any single color) wires, Reedy?s shrink tubing kit is your answer. Identify each wire with the appropriate color to prevent mishaps while maintaining the pro look. The kit contains three pieces each of black, red, blue, orange, and yellow shrink tubing.
