    I go away for the weekend and all the jokers come out...lol. Good stuff. I needed a laugh.

    To put the questions to rest... yes, I want to make sure it doesn't leak. I'm "worried" because I'm lazy and don't want to deal with a dead detector. I guess worried wasn't the appropriate word. Thank you everyone for the informative and entertaining answers.

    You can use the speaker submerged but your head has to be continuously underwater too to do that. There may be situations where just the control head is submerged continuously, in that case you need to use the headphones.

    Since the ones that come with the 800 are not waterproof and and you need wired to hear under water, is there a jack slot to plug in a set of head phones on the 800?

    How do they keep it waterproof?
    There is a jack on the back of the control head. It has a plastic dust cover that screws into the headphone jack cavity but that alone is not designed to keep water out completely at depth. The headphone jack has threads and ideally mates with a metallic waterproof headphone connector to keep moisture out of the jack cavity, but you can still submerge the detector without anything (including the dust cover) screwed into the jack because the back of the headphone jack is sealed with o-rings to keep water from leaking into the control head itself. Regardless, especially if you use the detector in salt water, it is best to use the waterproof headphone connector to minimize salt water intrusion into the jack. If you think salt or dirty water got into the jack cavity, then flushing the jack with freshwater is a good idea to keep the metallic contacts of the headphone jack clean of debris and from corroding over time.

    Owassokie, I agree with you (and others) Submerge the thing, even in a controlled environment. It's supposed to be able to take it. Otherwise, how will you ever know. Better to find out now than wondering in the field when you may want to use it as such. And yeah, it's winter, best time to get it repaired if it does leak (I'm pretty sure it won't) Fear not

    You need to get it down a little deeper to get to where the pressure will impact the detector, water pressure is the problem that is why minicab says 10 ft. max

    True but if you are only going into waist deep water, you just need to make sure it can take an inadvertent dunking. If the housing seal is not made up properly due to a manufacturing defect that will become apparent by simply completely submerging the unit. Otherwise, I wouldn't want to challenge the o-ring seals at depth unless I was planning to definitely use the detector at max spec depth which I presume is a small number of users. Every depth pressure excursion cycle probably weakens the seals over time. If I was definitely planning to take it down there, though, then I would definitely test it at max depth to be sure because you are right about pressure on the seals being the proof of the pudding.

    Vferrari once told me to it's hard to swing it in the water around 32 degrees so swing it soon as possible....I did mine the second day it was fine....
