Since my old go-to Stratologgers are unobtainium these days, I'm looking at Eggtimer. I'm wondering if anyone who's used any of the Classic, Quark, or Quantum models could give me an idea on how the beeper volume compares to a Stratologger? Is the beeper any different between models or the same? I have located rockets hiding in brush by ear more than once so for a difference of $20 I'd probably prefer whichever is loudest, if any.
