you are comparing apples to oranges. the whites spectrum is a $800 detector with 29 different adjustments and has a long learning curve. the deleon is about a $480 detector, that has three knobs and one mode switch. i guess i would ask myself how much detecting do i plan on doing. also what type of detecting will i be doing the most of. once you answer these questions then you will be able to better decide on what detector will best suit you. in the tesoro line, the detector that i would recommend would be the vaquero, its not a TID detector. but it for the price is a great little detector. you could buy it brand new one probably cheaper than you can buy the used whites and have a life time warranty. dont let it fool you it may look like a toy but does not work like one. they also have a learning curve, because it doesnt do the thinking for you, you are the one still doing that it just gives you the information. but its all about what would work best for you, if you know somebody that has a detector see if you can use it first to get a better ideal of what you want. sometimes dealer have display units that you use alittle in their yard to get more of a feel. my advice would be take your time and do your homework and get the one thats made for you. read these forums there are allot of people on them that have many, many years experience and are willing to help. i am a little bias, i think bang for buck tesoro is the best, but that may not be the case for you. like i say the worlds best detector is between your ears, and the detector in your hand is just a tool. good luck, keep us posted.
