Used to think the price difference was just branding hype. Full disclosure, had an Ocean Reef for years and thought I was fine. Then did a triple dive day off the Jersey coast and couldn't hear my surface team on the third drop. Tried a buddy's KM 37 the next trip. That first dive where the comms were crystal clear and zero fog at 120 feet? Sold. Night and day difference especially when you're hanging on a deco line in cold water. Not cheap but neither is a missed ascent.

Wait, $200 though? Couldn't you just borrow a friend's meter for that one job lol

Messed me up too honestly. Still can't believe feathers are basically tiny prisms.
