Tx Boost

[pulltabMiner]

I don't hear of too many people who use Tx Boost to hunt. I used it for the first time this morning at the park and WOW! For the first time since I began using the V3i, I saw the number 13 on the spectragraph. I actually dug up a small (1/2 inch) strip of copper from a hole that was easily 12 inches to 13 inches deep (I used the 9'' Propointer as a gauge to estimate the depth). I was using the C&J program with Rx=10,AM=75,Disc=92. 7.5kHz band. Recovery delay = 45. All else default.

I never tried Tx Boost before as I read that it would increase noise as well. On that account, yes, noise went up a bit but not enough to distract me or annoy me. I can't wait to try this out at my deep park where I know a carpet of silver coins awaits me at 11''-12'' (its no sin to be an optimist ). --short battery life notwithstanding...

Please be aware that using Transmit Boost quickly drains your battery pack. What I have done on really deep targets that the VDI is jumpy is use it only to help stablilize the VDI for a momentary reading, then turning it back off. I have it set on my 'Live Controls' for easy access. Some others may use it in areas where they had turned RX gain very low due to EMI, trash, whatever to help boost their signals.

If you can use it, Go for it.

I use it 90 percent of the time i also take 3 battery packs with me so far. I've only needed to use 2 of them I see a big difference in deep targets.

I went to my deep park at lunch and hunted for 30 minutes. I found a 1943D Mercury dime in a spot where I've hunted before both with the V3i and the AT Pro. The V3i said 9 inches when I pinpointed I dug up a 7 inch plug and the signal was on the side of the hole. I carefully began to extract it with the digger when I saw the thing was straight up on edge.

Now, I want to credit Tx Boost with giving me the very nice and clear 80 VDI on this coin but it also may have been my new 45 Recovery Delay that did it. At any rate, I obviously missed this guy before.

It could be all of the above or even your angle of approach would effect your signal, especially if it is on edge and deep. Good to hear you plucked another Merc from the ground!

The extra power is there is you can use it. My ground is too mineralized.

 

[jtalley007]

I always use it as well because we have good ground. I have been doing great at one of my old time pounded relic sites.

I know the boost has a lot to do with my success since I have taken two other detectors in there with that have low transmit power but are good machines and finds are scarce.

Even the V3i without boost just does ok. Turn boost on and I am finding things here that I have never found in 25 years like a NY coat button, just found a decorative spur 12" deep on my last trip and a dropped spencer bullet about a foot down with most of the shell intact.

Years ago and with other machines all I ever found was shot bullets and thought pre V3i that only shot bullets were to be found.

Not only finding better, deeper targets but averaging 10-12 bullets per 2- 2 1/2 hours of hunting which was as good as we did in numbers over 20 years ago.

I have repeated this in almost every place I have hunted that has been pounded. We have good ground so I can't speak of how one would do in minerals but conventional wisdom says it would not work at all.

Hope this helps, way back I posted a few hunts finds and need to post my last time out but have not had time.

I use TX boost a lot and love it...Be sure to carry extra batteries....

I've found boost to be very interestng. I tested it today using the 6 x 10 on my buried quarters at 6" and 8". Boost on, Rx as low as even 1, Disc at 93 and I could pick up the 6" quarter. RX of 2 was more solid. The 8" quarter demanded gain bumped to 7 for consistent hit of any kind(Boost on.) With boost off, the 8" quarter needs gain set to 15.

Has anyone done a study to know the trade-off in run time when using boost and lowering your Rx gain? Mine does detect th 6" depth very well at gain set to 2 while using boost. There might me a beneficial advantage to low Rx and boost, if running as low as 2 in Rx balances the power drain issue of boost. martin

Forget to mention...the V3i gets very quiet with that low gain setting. Quick GBing and non-falsing are nice by-products.

I would rather crank up RX to around 10 and leave it off. I can still get a quarter at 8 inches no problem.

 

[Larry (IL)]

What you should gain by using lower RX with Boost is less ground noise and EMI amplification. I other words, quieter operation at the expense of more battery drain.

 

[5900_XL-1]

Probably my soil, or the particular V3i machine I have, but my hitting an 8" quarter with my 6x10DD coil, simply won't hit solid at Rx 10. It takes 15, and even 15 is many times intermittent on any given day. Boost added in really helps me. My 10"D2 works at those levels though. martin

 

[burlbark]

It really comes down to soil types and what you can get away with.

I have posted some shots of the civil war bullets I am pulling out of a place that was hunted back to the early 70's and I am averaging 12 bullets every 2 1/2 hrs still after 7-10 hunts there.

It is mild ground and last Saturday got one at 14" and 15" with the leaves. What I am finding every time is the boost lights up the deep stuff and bullets that are smashed and turned on the side I am still getting at close to a foot.

The only explanation that there is so many left is they were not seen by past hunters including myself. I have been detecting since 1972 with almost every machine made and pound for pound, coil for coil in VLF machines this is the deepest especially with the target ID.

I would have to use a 15" coil on a Nautilus DMC 2-B to equal the V3i, bullets over a foot blare out in the mixed mode all metal portion to alert you then go back and use audio and target ID to determine if to dig or not.

Those super deep ones may require some ground scalping to say dig or not but that is how it is here in VA where there are 10,000 detectors in 20 square miles and some of the best relic hunters around.

I found a three ringer? in a park locally. It was down a solid 14" with trash all around it. I could not believe there was a target still in the whole after digging down a foot and my buddy came over to see what I was digging. I thought for sure there was a nail or something off to the side but 14" down came the bullet and no other target in the hole.
