Dear GPS Speedsters,
I have recently been informed of 2 Aquapacks failing and their NAVI GPS's failing from water damage.
As an extra defence adding a tight fitting water absorbant sponge, is an extra line of defence, as well as a rubber o-ring around the toggle switch. Sometimes vaseline around other water vulnerable areas can help though this can get messy?
PS: regularly check your aquapack for leaks
Some extra points worth regularly checking...
Aquapac related:
- near the seal, the plastic-welded seam is quite thin -> due to movement stress, sometimes these welds fail (I have one that did).
- look carefully at the clamped area for stress problems.
Navi:
- the SD-card/USB cover us quite a tight fitting; after repeated opening/closing, the part of the case that the little snap/click connects with, may eventually fail (my current unit suffered this fate) - I now use some gaff tape to keep it closed.
If anyone is interested,my perspex ones still don,t leak. $30 plus post.You can also use water crystalls to absorb any moisture.
As a back up, use the small re-seal plastic sandwich pack with the NAVi inside, and then place in Aqua Pac. I unfortunately didn’t do this until after the seam failure.
(supplier replaced pac, no arguments
Very tiny amount of dry lube on the card holder catch will prolong life. If I had realised up front when this part became tough to open, I would have worked out I had let some salt water come in contact with unit, and maybe saved the first NAVi life
I thought the units them selves were were proof
I wouldn’t of thought a few droplets of water would harm them.
Unless left in the sun the moisture may get to them.
I have a theory about this, I think the top seam damage can be caused by wiping out aquapac first. Air in the pac is then compressed and blows the seam. I now squeeze all the air I can out of the pac before I seal it.
And I no longer use the foam pad, because I think it helps trap more air to compress on impact.
Aquapacs seal a lot better if you close them, I learnt this one day, to my surprise, the Garmin survived
