Great continuity tester
Great little continuity tester - nice load remote with a bright light - trace 2 cables at once - it tells you if polarity is reversed - can't complain for the money - even comes with a battery and case

Genius little gadget
A colleague had one of these & recommended it to me. For tracing cables, polarity etc it’s absolutely amazing. No more 2 man or backwards & forwards terminal blocking to trace continuity. Highly recommend.
