Review on IPG Helix 7 Chirp DI G2 / DI GPS G2 / GPS G2 Fish Finder Screen Protector: Invisible Film Guard with Lifetime Replacement Warranty - Bubble-Free by IPG by Karthikeyan Behm

I'm halfway through with this product. I bought this for my Helix 7 DI GPS to protect the screen. Removing the protective film from the surface is a big problem, especially with wet, soapy hands, as the instructions stipulate. It's impossible to align it perfectly during application, don't worry. I thought having contested water on the surface of my sonar would be a bit of a shame, but it isn't. After applying, removing, and reapplying multiple times, I finally got close, but of course I now have a bunch of dust and a hair or two between the screen protector and the screen. It's there, however, but had some fogging that's common with screen protectors, so time will tell. I have another Helix 7 that I need a protector for, but to be honest I'm not sure if I'll buy this version for it or not.
