Increasing gain on Tesoro

[AUDuke]

Does anyone know if it possible to increase the gain in the all metal mode on a tesoro vaquero . Thanx, D

You didn't get and answers on this one. That's too bad. You might try this, if you're desperate. What kind of batts do you use? If "AA"s you're probably dead on this one. If 9v, I've found the range on 9 volters varies greatly. Anywhere from 9 to almost 10 volts. Thats almost 2 + volts, if they are in series. I brought this up a while back here. The battery that came with my new Garrett Pro-pointer was 9.9 volts. The battery is an Eveready. It is black with silver lettering and print. There is a red oval near the top with a black cat in it and a white "9". Providing (that's a big IF) there's no voltage regulator on the loop oscillator, I don't know why there would be) you could see a 10% power increase to that circuit, P=EI Where as the E would apply here. Maybe a tad more depth . You'd have to try it and see.
Hey thats all I got. At least this is a "no mod" mod. Good luck.

All experiments could ruin your detector but.........................You might want to get the schematic and isolate the TX circuit. Find out what tranistors power the TX and switch them out with ones that handle more power. Then give the circuit more power by cutting back on resitors that are in between the transistors and the power supply. You can try switching out the regulator if it has one with one of a highr voltage output and then see if you smell smoke.

Mod a Tesoro and factory tech's will not repair...so kiss your lifetime warranty ((good bye))...Would imagine unless you have mild ground unit would be unstable with higher gain...Don't fix what aint broke ought to cover it..

Ime a u.k laser2 user which is a u.s vaquero the u.k repair firm PENTECHNIC that does the warranty work for TESORO LASER also do upgrades on the laser2 they will increase the power from 14Khtz to 18Khtz or a or a switch which gives choice of either

@beatmachine and How to increase power. I am new to this, but am an electronics engineer. I can give you and anyone all the power they want. I wonder about this power thing I see on all the forums. One can put all the power you want in the unit via FETs and then carry all the batteries needed to deliver it. Has there been any unit to do this and is this why people are paying $thousands for these units. Maybe I am missing something, but I'm getting a very inexpensive unit and if it needs more power, it shall be provided.

Yer wasting your time, the tx power is not the issue. Its basically the magnitude of the returned signal thats the issue and more power won't necessarily improve it.
