Just can't decide Cz 1280X or cz 20 if I go with a underwater unit. It really would be used just for waters edge most of the time.Could someone tell me why or if the cz 20 is worth the extra $$$? If I decide on a land unit is the cz 70 a good unit? Surf is never high here in Maine. Was also thinking about the cz 70. Help me decide what one to get. My thinking out loud, it would be nice to take in into the water no more then 8 to 10 feet down, and I know I can't do that with a cz 70 but I'm not a water person so in reality I don't think i will be taking it under water. 99% of the time would be spent on shaw maybe in a light rain. What would be a better unit for finding jewelry rigs and coins? Ease of use is key as this is for the wife. All opinions welcome so keep then coming it will help me decide.I would like Fisher do to the warranty. I'll post what I decide on. Thanks! George
