Coil Weights Table

Recommended Posts

A piece of information I value and often can't find (or can find, but sometimes unreliably) are coil weights.  I'm attaching a list I've assembled.  These weights include the cable and the coil cover (unless noted).  The uncertainty of the measurements is estimated at about 2 grams.

Coils that are made with the same name and nominal dimensions, but for different detectors, will likely have some difference in weight due to the number of windings and possibly other discrete components (e.g. resistors) inside.  But you can still get an idea of a weight if you find a coil you're interested in but it's listed for a different detector.  An example here is the Detech Ultimate which came in at 532 g for the Fisher F75 and 549 g (as measured by Phrunt) for the Fisher Gold Bug.  A more extreme case here is the "Digger" coil for the X-Terra series at 481 g and the same housing, cable, etc. of a prototype Gold Bug coil weight of 437 g.

Good post GB!

Steve should add a coil weights section to the forum where you can add coils and their weight, could turn into quite a handy database.

Here is a few for your collection, I'll add more when I can be bothered removing them from the detectors they're on ?

Nel Sharpshooter 9.5x5.5" Gold Bug Pro - 424g

Nel Snake 6.5x3.5" Gold Bug Pro - 355g

Nel Tornado Garrett Ace Series 12x13" - 666g ( the devils coil ? )

Gold Monster 1000 10x5" - 472g

GP Series 11" DD GPX - 832g

Commander 11" GPX Mono - 813g

Commander 15x12" GPX DD = 1123g

T2 15" - 1081g

T2 5" - 341g

X-Coil 12x6" GPX - 848g

All had coil covers on.

I'll add those in tomorrow, thanks.  I also need to correct the size of the NF coil from 7x11 to 7x14.  Noticed a typo there.

Update:  File modification complete (see initial post in this thread).

You could use the bathroom scales to weigh the GPZ19" 'Dog'. Anyone know what it weighs?

Almost 2 KG Reg, 1830 grams, and I thought the T2 15" and Commander 15x12" were heavy.  It wasn't that long ago and my dog weighed 2kg, so it would be like swinging him on a stick.. he doesn't weigh much more than that now :laugh:

Heaviest coil i ever swung was the Coiltek 24" DD which weighed 1,840 grams. Even with the hipstick it got pretty uncomfortable after a few hours. According to Dave the 20" X-coil that i now have weighs 1670 grams. Will find out next week if its a back breaker.

A lot of people struggle with heavy coils and if you're swinging all day everyday it's nice to have a good light coil.

The weight shown may prevent you wasting your money and time and maybe letting you maybe get more gold. A fool will put up with a too big ("weighty, bulky, massive, cumbersome, unwieldy, ponderous, huge and overweight") coil to prove how strong he is and will lose concentration on the task in hand finding plenty of Au79 tiny atoms.

      Interesting reading if it works .....:
      Use Google translate for those not fluent in Russian I saw a similar post years back with Deus coils on GEOTECH it MAY be the reason why you can buy some electronic units only in Russia I am well tempted to build another nox for cheap....................

      Someday I hope to wake up in a world where I can order the detector directly from the manufacture with the coil I want. Right now White's and Teknetics are selling factory direct. OK, so where is my advantage? It's the factory. Let me order the detector and coil I want and stick it in the box and ship it to me. I can understand dealers not wanting to open already boxed units but the factory should not care. Keep some units unboxed and waiting for my order and ship me what I want.
      It is only a matter of time before somebody gets gutsy enough to do this and more. When I sold Ski-Doo snowmobiles you used to get what you got. Now you can pre-order machines and have them shipped from the factory with all kinds of custom options. Like custom decal sets... another good idea that detector companies could steal. It would be a blast to have a website where I could go, pick a detector, have a couple rod and handle options to choose from (S rod, straight rod, tall man rods, fat handles and skinny handles), different color and/or decal options, and of course whatever coils I want. Build it and see it built online and then order and ship. If this means I wait a little longer or pay a few more bucks, that's fine.
      Want to see it in action? Go online here and build your own Ski-Doo. It gets real fun when you get to the accessory page and you can see your model change as you add and subtract options. 
      Where is the company that will break the mold and think out of the box when it comes not just to building detectors, but marketing and selling them in new and creative ways?

      I recently broke my stock dd and replaced it with the 9x12 concentric. For the life of me I could not ground balance the machine in snow, just an inch or 2 it would false out like crazy. I did repair my dd but it is slightly out.
      Sent the 2 coils to Garrett along with the AT Pro and they repaired the machine, put in new firmware and confirmed the dd was out of wack. Went to use the machine over the weekend and still can't gb it with the concentric.
      Does anyone have a 9x12 concentric on an AT Pro and can confirm the issue? Not sure if it is the snow or the machine is marginal and sensitive to the cold or not.
      Thanks
