In our latest CTX 3030 video, Nenad Lonic explains the waterproof features of the CTX 3030 and provides some tips about how to prepare the detector for use in water.
This video should answer a lot of questions and discussions on the forums about the CTX 3030 and its waterproof features.
The CTX 3030 can be fully submersed in water up to a depth of three metres in both fresh and salt water. Waterproof headphones are available as an optional accessory as well as two waterproof smart coils; CTX 06 (6-inch coil) and CTX 17 (17 x 13-inch coil).
As an extra note, while the WM 10 wireless module is not waterproof, you can still make use of it when detecting in water, as long as you keep it dry. Note, the Wi-Stream radio signal from the CTX 3030 is trasmitted from the LCD module, not the main control box under the armrest, so if the LCD becomes submerged the radio signal will be blocked by the water. This will result in the audio signal becoming broken every time the LCD goes under water. Therefore if you’re planning on wading out deeper than the height of the LCD then you should consider using the waterproof accessory headphones.
An interesting tip from BarnacleBill on Find's Treasure Forums (http://www.findmall.com/read.php?86,1704518) suggests using a tether to ensure the detector doesn’t float way if you let it go to recover targets. There are two convenient tether points at the base of the handle that you can use to attach a tether.

Two of our resident expert TT bloggers, Gary Drayton and Tony Diana are avid beach hunters and will be providing plenty of tips for treasure detecting with the CTX 3030, both on land and in the water.

Now, sit back, relax and enjoy this short video that was filmed on a perfect autumn (fall) day. I was there and I have never seen anyone so disappointed to have to go back to work as Nenad was that day!
Thanks again, Ned
Now with the CTX 3030, I have all the great features I loved about the E-TRAC (and more!), and being waterproof means that I can wade in to waist height or more, still detect quite comfortably, and not have to worry about the detector getting wet! And with the WM 10 wireless module, I can mount that up on my shoulder and use my preferred headphones. That really is the beauty of the CTX 3030, you can hunt how you want to hunt, and take it anywhere you want to go!
I ran your question past the head of our mechanical engineering team. Here’s his answer:
“Keep the o-ring and the sealing edge on the battery clean, dry and free from damage. Any grease will only attract and keep dust, dirt and grit (beach sand) at the joint and potentially cause a leak. precisely the opposite of what you would think.”
