As Gord identified... making a waterproof "case" for a Sov would be quite an effort if you still wanted control over all the dials and switches. It appears akbell dismantled his Sov and reassembled it into his own case design. A beautiful job... but probably a bigger job than most people have the talent for.
That said... not only is my Sov waterproof... I can take my Sovereign 30 feet deep "including the meter"
Heck... I even use it with my S1 Sunray probe and I can still manipulate the controls!
Clarification: Although I can take it to 30 feet... I don't! If I wanted a detector for snorkeling or diving I would buy the Excalibur! My Sov waterproofing technique was strictly to protect my Sov against the waves when I find myself in waist deep water or if should I accidentally drop it in the surf
).
Obviously if I can take it to 30ft it must be 100% waterproof. It is...
First... let me clarify I only had to spend $20 bucks to make my Sov waterproof as I already had the main component. Here's the deal. I have an older video camera that I used to take scuba diving. The waterproof housing for the video camera was perfect for the Sov. :?: Say what? How can an underwater video camera housing be adapted to the Sov? The secret is... it's not a rigid case! Actually its "very" simple and anybody can do it. The question will be how much do you want to spend.
Think flexible! A line of flexible underwater camera housings made by Ewa-Marine. (Also read as: "The Worlds Most Expensive ZipLoc baggie!)

FYI: Be aware there will be a "bunch" of skeptics after looking at this solution! Skeptics that will say; "Holy Crap... its nothing more than a $200 dollar ZipLock baggie!"
Yep... I guess that's what it is... but... there's no getting around the fact that "IT WORKS!"
And "Yes"... because its initial purpose was to house a camera... the camera bag/housing has a camera lens mounted on it. And yes... the lens will serve no purpose in relation to using it with a Sovereign. Big deal. I saw it as the lesser of two evils. (i.e., Having a lens port that I don't use... or having my Sov ruined by a salt water dunking)
Also true, the bag solution is no where as cool looking as akbell's solution. Nothing about the bag looks professional! But it works!
Okay... the $64,000 dollar question. How do you handle the coil and headphone cables and still maintain the waterproof integrity of the bag? The solution is also available via Eva-Marie via their cable outlet adapter (it can handle up to up to 4 cables)
Actually you don't need the fancy bulkhead fitting... a small hole and a PVC bulkhead fitting (or maybe even some silicone adhesive) would seal the hole enough for the occasional wave.
There are other companies that make waterproof bags for other purposes so you can avoid the lens issue. I only used a camera bag because I already had it.
