In larger cruises small hand held like the one i got, 2 for $120, if i remember properly (your no1), may not reach from the from to the back of a group. They usually go 3-5 kmish Line of sight. I am going to get an in car one installed with a handset. But if you really want a hand held well i dont know 120 is a big diff to 50 odd. but it does do 8km. But that may still not be enough for a big cruise. So i would look into installed ones and get the cheapo in the meantime.
