Just in case you were wondering how many times your traps have been triggered, Goodnature has made the Digital Strike Counter. Packed into a tiny enclosure, the Strike Counter slides onto the CO2 canister, is easy to check and reset, and spends most of its day asleep. It is sparked into life when the trap is set off recording the action from the first kill up to 99. Because it sleeps so much, you'll get a few years between battery changes, even if you check it weekly.
