O - Ring

[GoVidGo]

Diver's lube. Use it on my AT Pro too....

seals it tight!

The O-rings don't roll and it will take up the slightest space water my pressure in.

$3 and a little goes a long way!

With a flat side and a rounded side, it is technically a D ring. These are used because it resists spiral failure. The flat side that forms the "D" shape keeps the ring from rolling, where a typical round O-Ring will start twisting or rolling under movement and will eventually fail.
In this instance, it may not matter. But I would think that the flat side (toward the detector) would help hold the ring stationary while you attach the battery pack. The rounded side would conform to the surface of the pack. I'll drop Minelab an email and find out for sure. HH Randy

Randy,

As usual you provide a very clear picture/explanation of the issue. The term "spiral failure" did it for me. I doubt Minelab will have much more to offer, but I would
still like to hear their take on it. If, in your "mind's eye", you visualize a cross-section of the channel and "D-ring", it seems obvious, at least to me, which way it should
mate up. Thanks for the major contribution you make to this forum.

Totally agree, but how many out there know about the actual shape of the "seal", until this post I never noticed and wouldn't have known.... again, I learn so much from everyone here and have so much more to learn on the CTX.... It will be nice to see if Minelab can give any further input on this... and IF it does make a difference.

just as I anticipated. The message I received back from one of the Engineers at Minelab is....... "By design the seal should have the flat face on the inside of the groove. However we did extensive testing before release and confirmed that it actually does not matter which way it goes in."

Thanks Digger! It probably would be smart to seat the ring as suggest, regardless if it "does not matter"

On another forum it seems that practically every person that has even had their CTX within close proximity of water is saying that it has leaked into the battery compartment... I am glad we don't seem to be experiencing the same problem and I just wonder why. Isn't there quite a few water hunters on here? Shouldn't we be hearing the same complaints?

Thanks Digger, appreciate you looking into this.... So from now on, I'll try to remember to put it in round side up.

I water hunt a lot and have never leaked!!!!
