CZ-70 Pro Evaluation
Posted by: twcook
Date: April 10, 2016 12:37PM
My hunting area is a salt water beach with black sand, sometimes in very large concentrated amounts.
I only want to hunt the dry sand, wet sand and maybe almost knee deep in the surf.
I was thinking about a CZ 21 but now I am thinking that a CZ 70 Pro may be the best value for me since I am not going to scuba or dive with it.

Thoughts, experiences? My budget suits a 70 much better and it seems to me that they use the same technology, the dual-freq. VLF at 5khz and 15khz.

Thanks,
Tim

Tim,
Yes, it's the same tech...but as Elton said, don't let it get splashed or dropped...even a little.

There's nothing remotely water proof/resistant about the 70 around salt water...and detector electronics don't respond well to salt water...even a tiny bit.
At best, it can handle a few raindrops.
:)
Good Luck, and

Hmmm, the documentation says it is rain proof / splash proof. So if you don't mind me asking; is this personal experience? Do you/have you owned one?

Thanks.

Another thing you may want to think about is that if anything ever does go wrong with them, there are no parts to repair them! You can call the Fisher service dept. and they will tell you the same thing.

Indeed it was advertised as rain proof / splash proof but should be alright as long as you have the female headphone port plugged up or a pair of headphones plugged in..
Saltwater and even air is caustic so clean with freshwater rag after every use....

Indeed. But rain/splash proof doesn't mean waterproof. It can't be dropped and dunked. Ever. Even for only a few seconds.

And I don't mind you asking, at all:
Yes, this is from personal experience.
Yes, I currently own one.
Yes, I've owned several others.
I wouldn't be telling you this if I didn't already know...I have neither the time nor the energy to make this stuff up.

Dan-Pa. used the proper term when he called Saltwater and even Saltwater ocean breezes 'Caustic'.
Even the aluminum shaft will corrode from exposure to saltwater, if not cleaned off regularly.

pine3874 gave you good info, as well, to warn you that if it gets 'borked', it can't be fixed by Fisher anymore.

You said, "I only want to hunt the dry sand, wet sand and maybe almost knee deep in the surf."

I predict the dry sand will be just fine...the wet sand also fine...knee deep in the surf may not end well.
It only takes one slip...and I don't care how fast you pull it out of the drink...and, yes again, from personal experience. :)

Thanks for the details Mike (and everyone else).
I guess I am still in the market for a CZ 21 then.

I currently use a Bounty Hunter Sharp Shooter 2 in the dry sand here and I know about salt air being caustic.
My apartment faces the beach. :-)

Always been debateable rain/splash proof .....some guys washed them off with a hose with no problems while others had problems hunting in the rain....all depends on the rubbers holding the parts together and the efficiency or lack of...have to agree if you are going to wade get the CZ21.....

Same is for CZ21. When is the need for service? Once a year, once in two years?
To be sure you have to send it in for service and they'll check the gaskets, too.

I have used CZ70 Pro's for the past 16 years and they are an awesome machine but I would not recommend hunting in the salt water with it. It is just too easy for it to get wet by a rogue wave or just simply dropping it in the water. I also used the CZ-21 for many years and it is a superb water machine. It may cost a bit more but you will be very happy you bought a machine you can just drop in the water when you get a signal. One accident with the CZ 70 in the water and any savings from buying it instead of the CZ-21 would be quickly negated. HH

The CZ70 is advertised as "splash proof" and rain proof as well. It has a water seal on the control housing :thumbup:

Yes, but also good to note, was that a large batch of CZ-70s were made with improper tolerances on the control box housing...making them somewhat less than splash proof and more than slightly 'leaky'.
Some cases don't completely close due to the double stack internal pc boards having too long of a separator 'stand-off' between them, if my memory is correct.
Unfortunately, it tends to be the 'good' serial numbers as far as performance goes.

Again, if I recall correctly, (I'd have to look at my notes) that in addition to the noticeable gap, you can tend to spot them because the front membrane switch decal tends to not line up properly, and peels on one of the front corners.
If you look closely on those models, you can actually see the gap between the upper and lower housing...visible from the front.

Otherwise, they still worked great.

Hi Mike,

I am aware of the supposedly good CZ3D (1021) serial numbers, but which serial numbers are considered "good ones" for the CZ70s. I am considering purchasing one!

Thanks,
HH
