did you have the origonal F75??

there isnt a heck of a lot of difference between the F75 and the LTD, aside from the boost processes. When in the regular modes, the LTD behaves exactly like my origonal F75's.
The LTD, when in BP mode enhances the responses of the targets, ESPECIALLY if you have to hunt over heavy overburden in the woods, or high weeds in the fields. Its been My experience, ay least in My soil that the LTD wont get much (if any) deeper "in the dirt" than the F75 will BUT, it will make the responses louder and easier to hear. The LTD seems to be a bit quieter and stabler as well, but marginally. DONT expect it to be a totally different animal.
I just returned from the NE on a long detecting binge, and used the BP mode almost exclusively. We hunted a lot in corn stubble, and the LTD was a BIG boon in those conditions. I could still get the same depth targets swinging OVER the stubble in BP as I could scrubbing in DE or JE. it made it a lot easier to detect!
Also, I have recovered a number of targets in the woods I almost certainly would have missed in DE or JE, due to the overburden. On "most' of those targets, I could still hear them in DE, BUT..only after scraping the overburden off with my foot so I could get the coil low and tight, and even then they were faint and hard to hear. I tend to do a LOT of experimenting when I'm out in the field, and always try to come up with a combination thats not only productive, but fairly easy on the brain as well.

All the basic things that apply to the F75 still apply to the LTD. Low disc = better depth and separation. High sens =better audio resolution. The only downside is the the BP mode not only enhances the response of the good targets, but the iron responses as well. You CAN hunt through it.......but in REAL busy sites it can take it toll on your sanity. We hunted a lot of iron rich sites, and after a bit of time you learn to recognize what to respond to, and what to ignore, but it WILL slow you down a bit. In sites where there isnt a ton of iron , its a dream machine! We also found that the wider louder responses of BP, ESPECIALLY in real busy of iron infested sites tended to mask smallish good targets like tiny flat buttons. You REALLY had to watch your sweep speed to get maximum separation. When the stuff got real think, DE or JE was a little better choice.
I consider the Boost modes just another tool to round out my machine. It isnt for EVERY site, but its real handy when you need and can use it. Overall, I think I'm able to use BP mode probably 70% of the time in my sites, and either DE of JE the remainder of the time. One of the big pluses of BP is, you can utilize a slower sweep speed in BP VS DE or JE, and still get great depth. Slower sweep speeds =better separation! in fact, a bit of a slower sweep in BP is almost mandatory.. Streak!
