OK, here it is . . . . . and to be honest, some of the past gudiance had me totally confused and that was after having made the antenna myself for water hunting and had been using it for a while . . . .
The Deus when running in the 18kHz mode is about as hot as you will find a detector for shallow water hunting when it comes to gold which is why most of us are in the water anyway. The only water detector that even comes close to the Deus on the
small gold is the Tesoro Tiger Shark. I've used the Deus in the water for the past 9 months or so and have found more than 2 dozen rings including 3 petite engagement rings with diamonds as well as several gold chains and earring backs. Don't worry - it hits larger gold items as well . . . again, had someone ask me if it only hit small gold
To make the mod a lot simpler, you need to realize that the only thing you are doing is providing a pathway for the signal being transmitted from the coil to the control unit . . . that's it. Sometimes we tend to make things way more complicated than they really are and some of the posts here and eslewhere on this mod did just that.
To sart with, you need a cable to provide the pathway. There are lots of cables out there but the one that I have found to work the best is
RG6 Coaxial Cable. It is readily available and you can get a roll of 50' or even 100' for under $20 so if you have some friends, you can have plenty to go around (if someone needs some, I have some extra laying around that I can send for postage costs). It comes in white or black - I opted for the white as it lets me see it underwater in all but the murkiest of water.
If you are going to leave the control unit on the shaft and only hunt in say knee deep water or less, you will need about 4' of cable. If you are going to put the unit in a case, figure on about 6' to 7'.
Strip about 1" of the outer jacket and the inner braided shielding from
both ends. Do
NOT cut the plastic core or the copper wire in the center!
Next, attach the stripped end of the cable over (on) the transmitter hump on the coil (located just outside of the charging connection). Use
plastic wire ties (had to say plastic as I had one person complain it did not work and found out he was using metal ties

). You can buy some that are reusable and can be released with a tab whcih makes it nice to put the mod on and take it off. One guy I shared this with uses
velcro strips which is another inexpensive option that is also reusable.
Run the cable up the shaft and attach it using velcro straps or tie wraps.
The other end of the cable needs to be placed on or very close to the receiver humps on the top of the control unit. The signal will then be sent up the inner conductor from the coil to the control unit. This addresses the problem where the communication link is lost once the coil is under a few inches of water.
There are a few options for wading deeper but this addresses the antenna mod which seemed to as elusive as Moby Dick at times.
Hope this helps . . . if anyone has any other questions, let me know . . . . . there's a section in the new book that covers this as well.
