SeaCure is a customizable mouth piece that replaces the current mouthpiece on a regulator. When you are scuba diving your jaw may get tired, which can become very uncomfortable. SeaCure is a great solution to try out, giving your jaw a much more comfortable experience while diving. You are able to mold your mouthpiece to YOUR mouth. The difference is more than noticeable.
"SeaCure Custom Mouthpiece, being moldable, cannot only perfectly fit every individual mouth but can actually enter the mouth all the way to the rear of the jaw employing all of the diver's teeth. The result is that the large rear teeth and tremendous mechanical advantage of the back of the jaw can now be employed to retain the mouthpiece/regulator unit during diving, greatly reducing the required muscle effort. In addition, because SeaCure has to fit only one mouth, it can be constructed in a much more sturdy design allowing transfer of the regulator/hose load to the rear of the jaw. Because if is not as flexible as conventional mouthpieces, SeaCure greatly reduces gum abrasion."
