This week we have experienced difficulties with two different Navman products, both have failed due to moisture ingress however both the plotter and the depth sounder are IP 67 (totally watertight immersible to depth of 1m for 30 mins) has anybody else had failures due to water getting in plotter tracker 5600 fishfinder 4200 both Navman cheers gavin
I've not had any failures with my Navman marine gear but I fit IP rated switch gear etc in the industry I work in (usaully IP68) and all I can say is ...
WATER ALWAYS FINDS A WAY!
Mind you if a manufacturer states something is made to IP67 standards (used on oil rigs etc) and you have fitted it to their specifications and still you get an ingress of water then there may be a fault or inaccurate description of that product. Worth a phone call don't you think?
I agree with Jizm that water will always find a way, I have ingress problems on a Raymarine Depth sounder and a Simrad radio. Both of which I was assured were made to the highest Standards.
You can always reinforce any vulnerable areas with silkathene and wrap any in line connections in self amalgamating tape. This stuff really does do what it says on the tin!
