Whites BHID 300

[automodeler]

I bought a BHID 300 for freshwater lake hunting.

I properly ground balanced it, had to back off the sensitivity a bit because of a lot of falsing, but then went into deeper water and started finding targets.

My problem is: everything the BHID picks up registers as a ring, except clad quarters. It also produces a beautiful, crisp tone... on rocks. I dug several of the rocks up after realizing there were no coins there, moved them to shallow water and confirmed the tone. Also, the coil is abyssmal at pinpointing. It registers more on the edge of the inner coil than in the middle, and henceforth, pinpointing, even in all metal (where it does the same thing) is a nightmare. Couple that with the fact that the lakes are rocky, and this becomes a fools errand.

Now, most of the targets I am finding in this particular lake (which will remain unnamed because of the HUGE amounts of old targets I've successfully uncovered so far with my Minelab Explorer II) are within 4 inches of the surface. I know from experience in digging deeper holes that the bottom is clay at about 6 inches. Should I be backing off the sensitivity even further so I can pinpoint effectively, or just waterproof my Minelab and get back to real hunting?

You should sell your BHID and waterproof your Minelab. Since the BHID is so crappy it shouldn't be worth much so why not sell it to me. I'd like to update my BHID 950. Please give me first choice.

Yes, you can turn down the sensitivity quite a bit and still get 6 inches in depth........you would probably get better pinpointing as well. Having the sensitivity set high often causes more troubles and sometimes reduces your depth....... the high beams in the fog theory.

I have a mnth old BH300 with the beast 12inch coil. and I run the pi$$ out of it. I run in All metal mode and run my sensitivity as high as I can. Learn the tones. Air testing and tones are key with this machine. It wont lie to you to often. Red is obviously a No dig . yellow and green dig away.

Tones. especially tabs and bobby pins. You will learn quickly.

learn your machine. run it as often as you can. I can also say this. it makes a damn good all terain unit. 1 unit that does it all.

Oh and FYI. the mxt has the same circ, board. just not waterproofed.

The BHID is dual frequency machine, 3 and 15 KHz. I think you might have meant to say DFX?

I suppose I'll try a few more times with the sensitivity greatly reduced and see if pinpointing improves. I'm going to fill a tube with water to sink the coil and then hit the lake with my pocket full of targets.

Regarding tones: I have really only heard two tones, one that is lower for the gold I am testing it on (corresponds to the yellow light) and a higher tone for coins (on both yellow and green lights).

Are the tones extremely close together in tone, or are they as different as the gold and coins I have tested?

Also, anyone have any help on why common rocks are sounding off?

Because they are very hot.........Its one of the benefits you get with detecting

I give up. Bought a Minelab Excalibur.

For Sale: BHID 300. An expensive floating machine that thinks rocks are rings.
