Interesting setup 
1. Why such a small coil ? You need max coverage on the beach and in the water. The competition will eat you for breakfast, I think. 6" coil =
2. What are the two black toggle switches for either side of the hand grip? Do they have a secret purpose.
3. I think those boxes will leak, not enough strength in the latches. They are for your lunch to stay fresh, I think. Good spot for a cold Bud
4. You will have a hard time keeping the box underwater. It is much too big for the detector.
5. A big wave will snap the box off, maybe?
I don't mean to sound too negative but that setup will cause you trouble. Much better ones if you look on the internet, I think.
Maybe version 2 ?
Don't forget to seek advice if you need help with your project. Some of the guys here are experienced and very friendly.

Methinks Captainkirk isn't aware of the benefits of that harmless looking 6" coil.
I'm curious to know if the metal pole is a bad idea or not. Any flex in the pole will in theory trigger a response from the coil.
The container might possibly hold too much air which will cause more pressure on the seals as the detectorist descends.
Should be perfect for short depths and beaches.
Nice job though and it looks like he thought hard about the best way to mount the system.
Bravo!

All efforts made to waterproof a detector are commendable but any design weakness will show itself very quickly. Those food fresh containers will leak underwater, I am 100% certain on that. They are not designed to be submerged underwater for any length of time. The latches close with minimal effort and open again very easily. I'd hate to see a good detector ruined by 1 drop of saltwater.
Nothing wrong with a 6" coil but I have never seen one used in the beach or water....8" is even rare. No need unless it's trash infested, rivers or lakes maybe.
How does it perform ???? We need feedback on this design. The two toggle switches serve what purpose?
Good, honest and polite constructive criticism will be to the benefit of everyone, designer included. There are many good underwater designs on the internet, I just feel that the above is not one of the better ones....lets see Version 1.1

PS I have been detecting for many years but only recently joined and posted. I read a lot on the forums but rarely make posts unless I feel that I can make a contribution somehow.
PPS You could have done without the headphones for this design. You have a TID. Lose the headphones and the hassle of them washing off. Now you gotta admit that's a good idea of mine

Finding a suitable waterproof case for a stock land unit requires a great deal of planning and preparation.
I think carpenter's have a saying of measure twice and cut once. Well for making the final decision on a waterproof case, it's more like measure 10 times and drill once (or in my case then twice).
Generally, the simpler designs work best. If you can avoid any unnecessary holes in the case then so much the better. The above setup was submerged in freshwater for several hours with regular but gentle tugging of cables and robust handling in order to replicate real outdoor use. This procedure was then carried out a further 3 times. 100% dry. The latch has a very strong and even pressure across the blue rubber liner. Detector is turned on, controls set and forget, snap it shut and then ALWAYS a freshwater rinse before opening the case to turn off. Agreed, the GQSS is very easily incorporated into the Pelican case due to it's low profile and rectangular shape.
