F70 Boost Question

[rob]

I went back 6 months to see if the question has been asked previously but I would like to know if the F70 has a "disc boost" setting like the F75 & T2. I think the slow process is the deepest but is there a disc range that will put the machine in overdrive?

Thanks for you're opinions in advance...

I don't own one but I'm pretty sure the F70 doesn't have the boost.

From what I have been reading from rocket Tom and others, Dave Johnson has stated that SL was indeed a precursor to the boost on the other models mentioned.
Also, if yo set your disc below 4 and if I remember correctly after 20, there is a slightly different method of discrimination the F70 switches to, and the result is a slight increase in sensitivity.

I have read a couple of posts by owners of both that on test gardens the F70 in SL using the F75 DD coil can match the F75 and maybe the T2 in boost, but I have never tested this myself.

In my experience the SL mode vs the DE mode is deeper, but I haven't used it much, only when I loose a signal into a hole down deep or I get a really faint signal do I switch to SL mode. My experience shows me it's around 2 inches deeper depending on the soil, but the SL mode is less stable than the DE mode, perhaps you need to ground ballance in the SL mode, and/or adjust the sens and thres to settle it down, then you could loose the added depth that you just gained by having to turn the machine down to stabilize it. Again, I haven't fooled with it much, though and shouldn't be considered an expert on its capabilities.

Good decision.
Using the F75 coil on my F70 in my good soil I just acquired and dug a target that the F70 ID'd pretty much right on...at 14" in depth.
This was using DE, not SL.

I can handle a lot of noise but some sites SL is just too noisy even for me.
At areas where I can use it SL works well.
Not all that concerned if DE can get me depth like this.

i also had heard the SL on f70 was a precursor to the boost in the other later machines. The SL mode really surprised me at times, especially when i had an iffy but deep signal, i switched on the SL and it certainly gave me a more definitive signal, and therby affected my did or no dig decisions. Found some deep silvers that way. Im used to the 75ltd , but would be ok using the 70 again, found a lot of good things with it, CO

Its Like the Boost,
Its the precursor to Boost,
Its near what Boost is,

But! its not Boost like the F75.
What I understand about the Boost mode on the F75 is its not really designed to go deeper in the ground, though it does, but its better used it area where the grass or stubble keep you from getting the search coil close to the ground, or to say if your hunting in tall thick grass and your search coil is well above average ground height then the Boost process really helps to overcome this.
