I had a SurgeGuard 50 amp unit and it fried itself, and I thought the pedestal too, due to water intrusion. The unit simply wasn't sealed well enough to keep all the water out. It was never immersed in water, but it spent a lot of time outside in the elements.
I think the Progressive unit has a better design and seems less likely to suffer from the ailment that killed my SurgeGuard. And the Progressive has a limited lifetime warranty, and the SurgeGuard only had a 1 year warranty. I believe the new SurgeGuard has a limited lifetime warranty also, but could not swear to it.
