Looking at Uber expensive detectors. As we all know White's is on the way out and the V3i will not be available long. This may be the last chance to get hands on a factory new unit. In light of that it has crossed my mind to get one as a historical investment. Now with all that out of the way, we know it is heavy and that it loves batteries but can use Ni-MH batteries in the pack. Weight, nothing we can do about that. My mind is more about the longevity of the V3i, is it a very durable detector? I know all about the multitude of settings, and that is one thing that draws me to it. A Tinkerer's dream, more like a computer than a detector. Bottom line, is it worth the price?
XP Deus. Had an ORX a while and loved the weight and ease of use. Hated the wireless headphones and they dug into my ear but I tell ya when it is hot weather that would sure be better on you. The ORX was somewhat crippled compared in settings, only giving 3 tone audio. It also had higher frequencies than the X35 coils do. The model I am looking at is the one with WS4 headphones and 9" round X35 coil.
Between those 2, which is worth the bucks??

I see that the coil itself has a battery, in it ? question how hard is it to replace one , or is it even possible ?

Here are three detectors that offer three different ways to do multi-frequency.
First up, the detector on the right, the XP DEUS. This detector allows you to choose from one of four different frequencies, and run any single one at a time. You can choose from 4, 8, 12, or 18 kHz.
Second, we have the detector on the far left, the Minelab CTX 3030. This detector looks at a range of frequencies and analyzes several at once. Transmitted frequencies is a bit of marketing magic; all that matters is what a detector processes. The CTX 3030 processes two or three frequencies simultaneously, comparing the results with advanced algorithms to deliver target information. There is no option to process single frequencies.
Finally, the detector in the middle, the White's V3i. This detector employs three frequencies, and is unique in that it can process and compare results from all three simultaneously, or run any one single frequency. The choices are 2.5, 7.5, and 22.5 kHz.
In a nutshell low frequencies are less reactive to ground minerals and produce cleaner signals on coin size high conductive targets. Low frequencies also better discern ferrous from non-ferrous items. High frequencies are more reactive to ground mineralization and have more issues identifying ferrous trash, but respond better to small low conductive items. Frequencies under 10 kHz tend to be "coin frequencies", 10 kHz to 15 kHz is a good "all around frequency range", and over 15 kHz tends to be the realm of prospecting detectors, though higher frequencies are seeing more use now with others attempting to pull small non-ferrous items out of ferrous trash. European hunters looking for small coins and relic hunters looking for bullets and other items are leaning higher frequency these days.
Usually choosing a single frequency will deliver the most power and depth. That is why you do not see multi-frequency nugget detectors, and why out of the three detectors discussed here the Deus with its 18 kHz mode and V3i with its 22.5 kHz mode offer better potential as prospecting units than the CTX 3030. Detectors that process multiple frequencies have a clear edge when running on mineralized salt water beaches. A single frequency can handle the mineralization, or the salt effect, but not both at once. Multi-frequency detectors are the preferred solution for salt water beach applications (not counting PI detectors), and so the CTX 3030 and V3i have a clear edge over the Deus in this regard.
Multiple frequency analysis can offer superb discrimination capabilities. When people talk about depth on multi-frequency detectors what they are really talking about is accurate target identification at depth. Many detectors will detect deeper than the multi-frequency units, but not while delivering accurate target id results. The Minelab Explorers and CTX are generally acknowledged as being on the forefront in this regard, no doubt due to the highly secret algorithms they employ to deliver target id results.
Anyway, the three detectors here have three different ways of handling the options. In theory the V3i offers the best of both worlds - the ability to run any one frequency or three at once. In practice the V3i is so complex few people ever fully master its capabilities but I do think they have the right idea. A much requested idea for the XP Deus, which is updateable via software, is the ability to run multiple frequencies. On salt water beaches at least this offers an indisputable advantage. Presumably an update to the CTX could offer the ability to run a single frequency, but so far Minelab has shown no interest in such options. It does appear that is where we are heading though - detectors that through proper design and software can become most anything the operator desires.
