Had a great day on Sunday at Point Henry Geelong with a few spills - see Vic forum. however when I got off the water noticed that my Aqua Pac was full of water. Lucky for me I had the GPS in a plastic bag and at this stage no damage evident. I have a soft pack and have discovered a small pin hole in the clear panel on the front. Has anyone tried repairing this? Silicon, melting? or is it chuck away and get another?
Silicone is no good... I've had some success with SupaGlue - the trick with SG is to only use a small amount -> you cant squeeze excess like you would any other glue.
By *some*, more like just barely, but watertight. Once the glue dries, fill it with water to make sure no other holes exist.
Edit: I have also tried "welding" using a soldering iron - but no dice.
Try this.. James Hardie joint sealant,will stick to most stuff or see me for an almost bullet proof perspex gps case 
Mine just slowly fell apart over the course of a year. Lost my car keys and destroyed my so called waterproof gps. I suggest replace it for piece of mind.
I repaired one with the clear sticker method. Held well then the seam went.
I replaced it with a paqua midi $30 and so far have been more than satisfied.

Salty,
You're not meant to wear them diving 
I just put grey plumbers tape over holes although it can be difficult to read display depending on location. Sometimes I will fill Pacqua / aquapac up with water and see if there's any leaks (cleans out any residual salt as well)
