## Questions & Answers

**Q: The beeps on the one I just bought are audible but just barely.  Wondering if that is normal or whether I should return for a replacement?**
A: It’s not loud enough in a keelboat cockpit

**Q: can i set it up as a 3-2-1-0 minute timer?**
A: Yes, but the timer is awkward to use.  I use and really like the Gil timer which is much better.

**Q: How long does the battery last?**
A: Our battery has lasted years with lots of use

**Q: Is the watch water proof and to what depth**
A: I don't recall exactly, but if you roll your dinghy or go for a swim it'd be fine. If you're planning on using it as a dive watch, I think you should buy a dive watch.
