Nice, accurate and simple dytter
This little device is a nice complement to my alitmeter, I set the signals to go off just below break and preferred pull altitude, as well as hard deck for reserve deployment. I often forget to turn it off during the week, but have yet to run out of batteries.
The dytter does sometimes go off during manouvers under canopy (Spectre 150), but I don't find that distracting.
The case cracked last year, and L&B replaced it to me for free. I've heard similarly great things about their customer service from many others, and if/when I feel the need for a digital hand alti, it will be an L&B.
