Dear Coral-Listers,
Can anyone recommend an easy to use, durable, handheld GPS unit?
The units are carried in the water while snorkeling. We use a  
combination of waterproof cases and bags to protect them, but there is  
occasional leakage. We use the units to mark our research sites out on  
the water, so we just need to be able to see the coordinates of our  
locations, no maps or fancy features necessary.
We need something that can handle some water contact and that has a  
TRULY watertight battery compartment- the compartments in our newer  
units corroded despite being 'water tight'. We also need the unit to  
withstand normal wear and tear of frequent battery changes and  
button-pressing, which our newer units did not either. I have a single  
unit that is about 12 years old; it has held up great and has outlived  
the newer ones we tried (Garmin 72H). We would appreciate any  
recommendations on waterproof bags or hard cases as well.
