Well I do remember it was the second digital CZ and replaced the CZ7 which had a problem with a slow pinpoint and using batteries while not in use. Never heard of any problems with this unit from friends or forums...As far as differences from the CZ7Apro series the CZ7A is a rodmount only and runs on 12 AA batteries under the armcup like the old 1266. Its a little heavier than the pro series but its weighting and ergonomics make it feel lighter..Has the same abilities as other digital CZ relative depth and stability and is fitted with a short cord as it can't be hipmounted. I liked it as the 12 AA batteries give 80-90 hours and as the control box is screwed on its more stable swinging.Didn't seem to sell well as everyone must want the ability to hipmount and not because its not a good CZ..
We realize condition and the like play a lot in pricing but feel #350.00 to $400.00 is more in the ballpark.
Rough guesstimate of age is probably late 90's but wouldn't worry about age as its a dependable unit and hope I have helped...
I would think the CZ7A pro manual would suffice as workwise they are the same, also with the exception of an added tone CZ70 manual would likewise work...
