Have always used xlt preset coin and jewelry mode with very good success but would like to start hunting in Relic mode. My question is why are the tones different as in real low target tones compared to the coin and jewelry or the coin mode. I noticed the tone frequency is preset to 226 compared to 231 which is for the other preset modes. Is there a reason for the change? since I am used to hearing the same audio from the other presets, the extremely low tones are hard to get used to. I am interested in lowering the discrimination by trying the relic mode. I have seen alot of post where this is the best program for really learning the xlt. Any input would be appreciated.
