Question - LF Coil To X35 Coil ?

[E-Trac-Ohio]

Hi Guy's - A quick question ...

I've read what XP has to say about their own Coils but ...

What differences / improvements did you notice yourself when you went from a LF Coil to a X35 Coil ?

Thanks & Good Hunting !

I don't think the X35 coils will be much different from the LF coil unless you change sizes. Size for size they perform about the same. If you want something different then the change from LF to HF coil is a bigger difference.

The biggest advantage of the X35 coils is the addition of the 25 khz frequency mode. That is a game changer for relics and jewelry/gold hunting. The other advantages are more subtle - The lowest frequency., 4 khz, is now adjustable both in frequency offset and in transmit power. This enables you to boost power into the ground at the lowest frequency to provide maximum depth performance, especially for high conductors like silver. Speaking of frequency offsets, on the LF coil, if you used frequency offset, then your Tx power was locked. Now you can use frequency offsets if needed to reduce EMI without losing your ability to adjust transmit power. In high mineralized conditions, LOWERING transmit power can be advantageous to improve overall stability and performance. There are more in the weeds improvements in terms of coil manufacture and a battery upgrade. But the changes I mentioned up front are BIG DEALS and have really obsoleted the LF coils. At this point, since the X35 coils have been out nearly 2 years and the LF coil manufacturing stopped about the same time, any LF coils you might purchase used at this point have probably already used up their battery warranty. So at this point considering the comparably limited performance of the LF coils vs. the X35 coils, means I would forego the LF coils and opt for an X35 if purchasing a coil at this point. Otherwise, use your existing LF coil until it drops dead because the resale value is practically nil. HTH.

Vferrari covered it very well. My only addition to his differences/improvements is that overall the X-35 coils are quieter than the LF coils running at the same frequencies. They handle EMI better right out of the box and they handle mineralized ground better too as in much less noise at higher sensitivity. I did not get a chance to try them at a saltwater beach yet......

Thanks for your replies on the X35 coils !

Good Hunting !

Expanding upon what vferrari said about the addition of 25 kHz; if you set ID Norm to off, TIDs of high conductors such as most US coins will be pushed into the 90’s. This is ideal for coin shooting, in my opinion, as even the wheat penny will display a TID of 93. I use a 25 kHz coin shooting program for those quick after work hunts when I need to cherry pick because I don’t have hours upon hours to dig everything.
