Is this a tech dive trip or a recreational dive trip? If it was recreational I prefer to pack light. 1 mask, 1 primary light, 1 computer, etc… If my mask breaks I’ll stop by and buy one from the many shops.
To me it’s not worth the Hassle to bring a ton of spare/redundant equipment.
Technical diving trip… You’re gonna need more gear 😉
Maybe we can get Woody Harrelson, he can talk about Rampart.
