New HRM watch/Fitbit style recommendations.

DaSavedSinner

first off I currently using a Polar FT7 but my wife insists that I get a new one since mine has been acting up. I would like to get something like the FitBit Surge but I have heard mixed reviews about plus I would rather something waterproof. So the main thing is it must has a built in (not strap) constant HRM like the surge. Notifications are a perk but not needed. Gps not a big deal to me. Also has anyone used an Polar H7? It is compatible with my FT7, waterproof, & only like $

So what have you used?
