Water hunters ...... this may be of some help

A post by one of our members here, and he has a very good point. This might explain why some users are having water leakage in their CTX's.

Can an Admin please make this a sticky !

Thanks.

The battery compartment is plastic as is the battery holder - which has little dynamic for transferring (conducting) heat. The inside of the battery compartment would likely be warm after removing from a hot car. Placing the detector in cold water would slowly cause the air inside the comparment to cool - which decreases the volume occupied by the air, which could bring outside water inside (theoretically) - if (big if) the seal allowed the moisture through.

I use silicone grease along the seal and joining surface (just a thin coat). I've taken a fairly hot detector into the water often enough, but never had a leak. It is possible that under the right circumstances the compartment's cooling air (which causes a pressure drop within the battery compartment) could draw a small amount of water through whatever weak area is present (especially if the user is near the depth limit) - wherein the deeper in the water the comparment is lowered the greater the pressure differential across the seal, the greater the chance for leakeage.

So, good tip.

I never thought of the heat issue either, in fact I haven't even taken my CtX in the water yet, but have really been wanting to and needing to as I have a very nice set of waterproof headphones I need to test! I've been kind of afraid to test it out though after all the stories I've read. I'd only be taking it in fresh water rivers and lakes, at this point anyway. I think I read something else posted about using the AA Battery backup unit instead of the Lithium battery when I go in the water. Sounds like a good idea to me, I believe it was posted by someone in answer to another post about a battery that got water in it some how.

I want to take every precaution possible when i take mine in the water, and if it means keeping my detector internals dry, I don't mind overkill. Putting some silicon grease along the seal like Johnnyanglo mentioned sounds good to me, but do you only put a little tiny bit just along the edge of the seal only where it mates with the inside of the battery or on both sides and how much is too much, knowing me, I'll over do it, maybe I should just not try it LOL. Thanks for all the info posted on using the CTX in the water!

I took my time going into the water at Cape Cod waters this week, everything went well. I always use a little silicone grease just in case. but I don't rush into the water and submerse the ctx 3030 into the water and I use a silicone band around clamps. Don Coco Tyler Merrimack,NH
