Having extensively researched the Protrek and G-Shock lines I decided this was the best fit for me.  The number of features and the amount of information packed on the main display screen is just awesome.  It isn't very heavy and feels smaller on the wrist than it looks.  Nearly as tough as a G-Shock and with more functionality than everything except the new Gulfmaster, which is twice the cost, I enthusiastically recommend this watch.
