Auto shutdown ST-305

[g.romani@gruppoigr.com]

Hi,
I'm new here and I hope I'm not wrong
I've a ST-305 Transmitter, and I work for a long time away from the instrument with a SR-24. Is it possible to turn off the automatic shutdown of ST-305? If so, how?

Most you can get is 4 hours or so using low. You might be able to send it to seektech for a power control disable but if you can afford that you should just get a better unit like the 33q+ or R model. The 33 has an interface to make choices the 5 watt is just for basic locating

Thank you very much Cuda for your response and availability. Honestly I'm a little disappointed with Ridgid. I bought this tool to connect it to start point and trace the cables, but if I have to return at start point every hour or 4 hours it is useless. I will try to call seektech to disable power control. I will share their answer for information.

it is only a 6 C-Cell power source it will always run out of power you need an AC plug in power source to be able to do hours and hours of work and not return. Why is it taking so long?

Too bad they don't have an adapter that would let you connect 18v batteries externally. Wouldn't be too hard to make a retrofit kit. Build the voltage regulator into the space where the C cells were housed, give it a jack to connect a cable run to your external battery with an adapter that slips on the top of the battery like the USB adapter. It uses six C cells so 9 volts which just happens to be half of 18. Should be easy to do.

I wish I still had my ST-305 now so I could build one for it. Not for me but to sell to others. It would be possible to make it to mate up with any 18 volt battery, RIDGID, Makita, Milwaukee, DeWalt, you name it. I sold my SR-20 and the rest of the gear last Fall.

Anyone know how much power the ST-305 draws?

I'm looking to make an external battery adapter like I mentioned above.

I emailed RIDGID and asked about the ST-305. The answer was it will run about an
hour at max output or 5 watts and at that power level the ST-305 draws about 3 amps.
