AC/DC Clamp on ammeter

While trying to untangle the battery wiring on our new boat I decided a clamp on DC ammeter would be a great help. Found one at Sears and it is one of the best tool purchases I ever made. It measures DC current and also gives the direction of current flow. By checking the current at one of a cable and then doing the measurement at what may or may not be the other end you can easily determine if the cable is the same.

The unit does not just do current measurements but also measures frequency so you can check the genset to see if it is really outputting 60Hz. Of course it also measures AC/DC voltage, resistance, capacitance and has a temperature probe.

Price was about $60-70.

Just for clarification, I have no connection with Sears, just that I have found this to be a really useful tool.
