Well great question Monte. Ive had really good luck with all of the frequencies. If I had to go on which freqs ive made the best finds with to pick one it would be the 17.5 or we can just call it 18 cause I cant remember exactly what it is. When I say this im also talking about all my time with the deus also going way back. For me the 18 seems to be the strongest and best for just general hunting in all types of conditions. I have not tested this with air tests or setup tests to prove this. This just from my time and experience in my sites. The 18 kHz seem to be the strongest. IF ya watch a lot of Xp videos a lot of users swear by the the higher freq for iron hunting. The 26-31 kHz. My opinion on those freq is that they seem to sensitive for me and im digging to much bird shot at 4" deep and chasing bird shot round and round in a hole lol. IF your jewelry hunting it would be the way to go for sure. I usually jump back and forth between the 12 and 18 kHz are my favorite. On the ORX I like to run coin deep and change reactivity to 3 and use 12 or 18 kHz. Disc depending on site conditions. I try and keep disc as low and I can stand. Ill start at 5.5 and move it up if need to. I never go over 10.
