Review on Lisle 65150 Flexible Back Probe by James Small

Probably the thinnest rear sensors on the market. They slide between core insulation and seal without causing damage. A variety of angle probes allow you to select the one that best suits your specific task before resorting to wire punching. The universal socket end connector mates with the standard DMM banana plug for protection against short circuits. Or you can use the supplied plastic-insulated crocodile clips. They arrived earlier than expected. My experience with Lisle is that they aim for practicality, not quirkiness.
