Has anyone tried getting a SunRay FZ-12 coil installed on a CZ-20?

Good evening vernt, saw your post, you must use your cz20 on land also. With the 10 1/2 inch coil its yes areal challange to pinpoint. Would you share any helpful info for land hunting? Thank you very much. jr

Hello jr,
I don't know what helpful tips I can impart. I hunt mainly on the wet and dry beach sand,not on land, and a little in the surf. 99.99% of the time I hunt in the all-metals mode, so I try to hunt relatively clean beaches. If finds start drying up though,I'll consider using my Sovereign GT, but I like to hunt faster than the GT likes. Anyway, when I detect something in the surf with the CZ I'll turn discrimination to 1, to help ensure I won't be spending my time digging iron. I don't, haven't ever, used my pinpointing button. Have heard too many stories of how this feature on the CZ20 is the first to malfuntion. So I just wiggle my coil to and fro, and left and right for the strongest signal. Sometimes lifting the coil up higher and wiggling helps too.

Good afternoon vernt, thank you very much,never heard that one on the pinpoint, seems tough to use anyway. thanks again, jr

Would probably have to be replaced by the factory to insure its water integrity being a underwater unit and Fisher sure is not going to install a Sunaray coil on a Fisher unit...I have used it on land machines and works quite well and pinpoints just as well as the stock Fisher coil.

You're right Dan. Fisher wont't do it. Although they will work on a unit after it already has had an after market coil installed on it, I'm sure there are some strict limitations on what work they will do and liabilities they will assume. So it would be up to me (or whomever) to to do an exceptionally good sealing job. I was just curious if anyone had tried this.

They have and may still make in line connectors. Of course matching up the correct wires could be a headache as you have two different companies and the color coded wires may not match up. I would think a learned individual could match up a land CZ with the wiring but then again do they use the same color combo's for both. Perhaps a friendly Fisher tech could help...

I have taken my 8" off my CZ20 and put on the 10.5" coil opening the detector and closeing it was not a problem. There is only 4 screws inside the battery houseing. When putting the screws back in just make sure you dont over tighten them. But they do need to be pretty tight. I then put silicone on the screw hds. to make sure they dont vibrate lose. I dont like to mess with the circuit board, so I cut the old cable about 4" away from the board. Then soldered the new cable to the old instead of the board. I used a 10.5" from a CZ5, and the wire colors all matched up. I have heard if you put the FZ12 on your CZ20 that you can get the best performance if you tune the board to the coil. Some of the boys in South FL. are useing this setup. They have someone in their area who does all the tuneing for them. Talked to one man down there, he says the FZ12 is 3" deeper than the stock 10.5" coil. Kevin Reilly of Reillys Treasured Gold might be able to put you in contact with the man who does this modification. Hope this helps, Mark

Good evening, gentlemen, talked to Jerry the repair tec at fisher this week, he said there are water proof connectors avaiable nowdays that were not when fisher designed the cz20. I did not ask where. The coil wire is a 4 wire configeration, Mark in your modification, is any of the 4 shielded? If not , couldn't the cut be made on the exterior? Then the waterproof connector be installed on both, control box and coil, making for easy future swap. Also couldn't the coil wire be simply cut near the control box, {if it is not shielded} and the replacement coil wire also be cut, soldered, and sealed with silicone, yea not as proffesional, but useable. What do ya think? jr
