hmmm......
Have you ever wished your shot timer had a headphone jack? Well... just made it happen. I added an aux out on my Competition Electronics Pocket Pro Timer II (CEI001) that switches off the main speaker when headphones or an aux cable are plugged in. Now I can route beeps from the timer directly into my ear protection. 90% of you probably won't care...but if you do... here you go.
