Hey I just got the idx pro today and was testing it out in my yard and it beeps twice on every target when I swing to the left . Is this normal?
Well, let's run down a few questions first to try and get a good answer for you.
Q-1: Did you happen to get a 'modified' IDX Pro with an external Threshold and Ground Balance control? If so, make sure you have adjusted a proper Threshold audio and then adjust a very slightly positive GB in he All Metal mode. If it isn't modified then ....
Q-2: Is the Frequency Adjust control set at the Factory Preset marker (fully clockwise)? The internal GB trimmer needs to be adjusted for proper operation with the Frequency Adjust control set at the factory Preset mark. Make sure this control is at the 'Preset' and then continue ...
Q-3: Did you first check for a 'proper' Ground Balance setting? If you are relying on the internal Ground Balance preset trimmer, do the following: Hold the search coil about 6" over a bare spot of metal-free ground; flip the trigger-toggle forward into the locked All Metal mode, or pull-and-hold the trigger-toggle to select the momentary All Metal Pinpoint; Lower the search coil to the ground and listen for a change in the audio Threshold hum; it should have a slight INCREASE as it
approaches the ground to indicate a 'positive' GB.
If the Threshold audio nulls out and goes silent as the coil is lowered toward the ground, that indicates a negative Ground Balance and you will want to tweak it a little to make it slightly positive. The Classic series models need a slightly positive Ground Balance, and if negative, they will false.
Q-4: Are you using the stock 950 search coil? It is a larger-size search coil and you should make sure the coil is swept about 2" or more away from the metal target to ensure getting a single-tone response.
Q-5: Did you check a round, non-ferrous target, such as a coin, in more than one location? An elongated target, like a nail or piece of wire or similar object, can produce a 'double-beep' if you sweep across it lengthwise. Also, you might put a target on the ground to check it, but there is an unknown target just out-of-sight to the side of the placed target, and that can produce a mysterious 'second beep' on one sweep direction, especially if it is ferrous material.
Q-6: Is a one-direction double-beep 'Normal' for the detector? No, it isn't. As stated, it can be from a target too close to the search coil, or an elongated object, or an unknown target close to the sample target.
If you relocate and use a different test area, and first check the area in the All Metal mode to ensure there is no metal in the 'test site,' then place a coin flat-on-the-ground and sweep the search coil over the target maintaining at least a 2"-3" coil-to-target distance. Also, make sure the search coil is in motion. If you go too slow, it is possible to get more than one response from some targets.
