Doc's Treasure Screamer

Has anyone tried Doc's Treasure Screamer Amp with their E-Trac? Would like to hear about your results good or bad and the ugly. Wondering how the amp would work on the wet sand at the beach.



Thanks

Old Beechnut swears by Doc's amp on his Excall. He has some videos comparing the differences. I would think it would work great on an E-Trac. You might post your question on the Excallibur and Scuba Diving forums so he will see it. I would like to hear his reply also. HH :minelab:
 
Thanks for the reply.

I speak with Joe quite often and we have discussed what the amp would do on the E-Trac. I was just curious if anyone has used one on their E-Trac with any good results.

Don't need any more volume, I have excellent hearing. I know for a fact that Doc's amp allows the Excalibur to achieve more depth by sounding off on targets that it otherwise would not make a peep on without it.

Not sure if an E-Trac would achieve the same results. From what I understand if the amp is adjusted properly to allow a target to pop through the threshold, the machine will sound off on a target deeper than what it would without the amplifier.

Been talking with Doc about the amp. It may present the appearance of increased depth by allowing deep targets to sound off above your threshold that you would not normally hear.

The Signal Enhancer lets you lower the threshold lower than you would normally be able to hear it, yet the Treasure Screamer amplifies the barely audible threshhold so you you still have a point of reference. You lower it so much that faint targets are not masked by the threshold and when the amp senses a target it locks onto it and amplifies it even more.

Sounds very interesting!---Are you going to try one on the Etrac & perhaps give us a report on it?
 
Kinda like what deep on is suppose to do.I have dug some ultra deep silver that did not give a high tone in multi tone conductive, just a hollow whisper but was repeatable so I investigated. Especially after getting that nice small "round" signal/response with pinpoint mode.
 
I would like to try one and see how it would work on my E-Trac. I have another forum member that has an Amp he purchased and set up to use on his Excalibur. He is going to conduct some air tests today with his E-Trac and see what kind of results he gets. I don't know what kind of results air testing will prove.

The Amp does not increase the depth performance of the machine. It allows targets the machine sees to pop through the threshold hum of the machine that are detected but too weak to ring through with an audible report.

I have noticed this on my GTI 2500 and my E-Trac before. I have gotten a TID response on the screen but no audible report, the amp locks on to those and boosts the signal above your threshold so you can hear it. In a sense I guess you could say it gives the appearance of more depth. Your machine may be able to see the target just not produce a tone above the threshold with out the amp.

If this works on an E-Trac it might prove to be a good tool. I just have not spoke with anyone that has any real world results with an E-Trac. Oldbeechnut has several videos on youtube with the Doc's Treasure Screamer Amp attached. He is able to get a signal on deep targets that the machine is unable to report on with it turned off.

If it works the same on the E-Trac it would be great. The E-Trac has a lot more adjustments that we can manipulate compared to the Excalibur, deep on and boosting the gain etc. The amp may produced some great results attached to an E-Trac. I have yet to find someone that has hands on experience.
