Hey all. I live in FL and mostly surf hunt.I sold my CZ70,to help pay for a CZ21 and an Impulse. I still relic hunt in VA,at least once a year.I also coin/relic hunt a little in fl. I have been detecting for 15 years,and hands down the best machine I ever used was the CZ70.(I owned two) The CZ70 can salt water beach hunt,shallow water hunt(chest mounted),relic/coin hunt.The tone ID,and notching are very user friendly.Here's my question.. should I stick to another CZ70,or give an F5 a try for my next relic/coin machine? Thanks.
