Rating: Not for Scuba - snorkle diving only
Reviewer: Eric S.
I like this watch - it is large and comfortable to wear. The functions all work as expected. It is a little cluttered making it difficult to read - the night glo does not last as long as hoped. This watch is advertised as a divers watch but once you read the fine print it is only rated for snorkle or skin diving - the WR 100/200 (10/20 atmospheres) designation means very little.

  • Yesenia:

    bafo bf-7030 usb 2.0 to irda-wireless adapteri dont remember where i got it. i dont rellay use it much with my macs (it does work though), because my decompression software (gap) is pc only. so, instead of using my macbook pro for logging dives and my netbook for deco planning, i just use the netbook for everything. i much prefer the mac, but at least the netbook is small and cheap both good characteristics for taking to dive sites.
