I haven't used on in salt (no beach around me) but from personal reviews I am getting it does VERY well. Ground balances very well and is stable. Any questions feel free to contact me. Love to help you.
All of the advertising, testing, evaluation videos and write ups I have seen are very conspicuous to say fresh water when talking about reviews. I suspect there is a reason. My personal opinion formed from test reviews is the AT Pro does well in fresh and not as well in salt water. As the weather warms we should see quite a few more testimonials on the AT Pro. I look forward to them.
