TerryinHawaii Posted February 19, 2015 Share Posted February 19, 2015 I would like to know the weight of the 14x13" Super D Search Coil with a Coil Cover? Has any one tried the GPZ 7000 for hunting wet sand at one of the California beaches? Link to comment Share on other sites More sharing options...
Steve Herschbach Posted February 19, 2015 Share Posted February 19, 2015 I will weigh the production coil in a couple days and get back to you on it. I myself am curious about salt water and whether the unit can ground balance into the wet salt range. Link to comment Share on other sites More sharing options...
Steve Herschbach Posted February 21, 2015 Share Posted February 21, 2015 OK, an indirect report from JP at http://golddetecting.4umer.net/t20896-silly-ml#201830 which would indicate that the GPZ may not be the best solution for extreme salt situations at this time. Probably OK on drier beach sands but still an open question. Will have weight info tomorrow. Link to comment Share on other sites More sharing options...
Steve Herschbach Posted February 23, 2015 Share Posted February 23, 2015 OK, here you go. Minelab GPZ 14 Coil with Lower Rod The Minelab GPZ 14 coil comes complete with lower rod attached. I assume of you buy one new it will also come with a scuff cover like all Minelab coils but I do not know this for sure. A scuff cover does come on the coil when you purchase the GPZ 7000. The coil assembly with scuff cover and lower rod weighs exactly 3.0 lbs as weighed on my digital postal scale. The lower rod assembly with nuts and washers weighs 4.8 ounces. The scuff cover weighs 4.3 ounces. The coil alone without rod and scuff cover is 2 lbs 6.9 oz. Compare this to the stock 11" DD coil on the Minelab CTX 3030 at 1 lb 6.2 oz with scuff cover and you can begin to see why the GPZ 7000 weighs what it does. To get proper balance for that 3 lb coil there has to be offsetting weight behind the handle. Even the 17" coil for the CTX 3030 only weighs 1 lb 15.8 oz.

Reno Chris Posted February 23, 2015 Share Posted February 23, 2015 Although you'd have to tear it it apart to confirm (and that's not going to happen), I'd bet a lot of that extra weight is the increased copper wire in the GPZ coil. Link to comment Share on other sites More sharing options...
Steve Herschbach Posted February 23, 2015 Share Posted February 23, 2015 Interesting tidbit. Yes, the longer rod assembly from the GPZ 7000 will plug into the CTX 3030. The CTX 3030 rod is 32" and the combined two piece GPZ rod is 38" GPZ Coil & Rod Assembly Plugged Into CTX 3030 However, the wide yoke could be difficult to mate properly to a CTX coil as the mounts are nothing alike. I am sure it could be done, but given the likely cost of this lower rod assembly plus need to "make it fit" this probably is not a viable option for most people wanting a longer lower rod for the CTX 3030.

No doubt about it. Link to comment Share on other sites More sharing options...
