There are differences, some subtle, some obvious...It comes down to how particular you are and what environment you plan on using it in...Look at DSS's web site, then look at some of the others, like Golem....If you can, try other diver's plates, including different harness set-ups....When you've come to a decision look at the SB classifieds...People are always selling plates....They are pretty indestructible.....Also take into consideration your wing selection....Most wings/plates are compatible, but not all.......
