Is this any good? its on sale at amazon and I was thinking about buying one but it only has a 1 year warranty!

The ORP meter in most of these is about useless in seawater. You will not find many meters any kind with a warranty of more than 1 year. You are better off with this pH meter which is much better than that Hanna.
