I spent last week detecting in Destin with the Manticore and Deus 2 both in the water and out of the water. The Manticore performed very well in the water however once I came home I got the manticore out for a little park hunt. Once I turned it on the external speaker had little to no sound. Tried factory resetting a few times to no avail. I did a search and found a blurb about pressure and the speaker however I never had the unit more than a foot under water. The solution was to remove the pod and pull the battery cap/bung to release the internal pressure. Removing the pod I noticed there was a large amount of water in the cap as I had the pod upside down in order to remove the screws. I would have thought this water would have drained out over the last few days but it did not. After drying the cap I removed it and wa-la we had speaker but at only half volume. I thought maybe water got in. I put the cap/bung back in and heard a pop at the speaker area and the speaker kinda worked a bit louder but the sound was off. I tried removing and re-installing the cap/bung slowly even rocking back and forth to try to release any pressure as it slid into place. Each time I had a different result i.e. no sound, muffled sound, full sound. Eventually I got it seated with better speaker audio but not great. I waited a few min and the sound finally went back to normal with full volume. I reached out to Minelab and asked about what I had experienced. They said this is normal as the popping at the speaker area of the cap/bung going in was proof the waterproofing was working. So if you have an issue with the speaker not functioning after water hunting then the battery cap/bung removal and reinstall is the solution but seems odd to me not to have some sort of pressure relief built in. One other note is the water not draining from the area of the cap and stem mount. I guess I will have to loosen the screws enough to split the joint so the water will drain or just remove the pod and flush out the salt water.
Curious what others have experienced.
