Just sharing this in case it helps someone new to the Legend. What made the biggest difference for me was slowing my swing down and doing a quick ground balance when the machine starts getting chatty. Also playing with recovery speed depending on if I’m in trash or cleaner ground helped a lot. Nothing crazy just small adjustments that made it easier to understand what the machine is telling me.
Happy hunting out there.
With the Legend and these more recent simultaneous multi frequency detectors, swinging really fast while trying to discover a deep target makes zero sense. Swinging really fast with very short swings while actually investigating a possible deep target after discovering it is a good idea.
Swinging the Legend's LG28, LG30 or LG35 coils really fast during full discovery sweeps is crazy. Those coils are just too big and there is no way to control them and keep them parallel to the ground during full 4 to 6' sweeps swinging them too fast. Swinging a bit faster with the LG24 coil is doable.
So swinging much faster to get more depth using any coil on the Legend while scouting or gridding an area is not something I would do. I know Paystreak does that but he is usually swinging really fast with shorter length controlled swings in really trashy areas with high mineralization using a smaller coil where maximum depth of detection is not important to him. He is much more concerned with ground handling and EMI mitigation than with getting an 8 to 10" deep coin sized target with a 6" wide DD coil.
Adjusting the frequency shift to get more depth on coin sized targets........That sounds dubious to me. I would just switch between M1, M2 or M3. Frequency shift within M1, M2 and M3 is going to be a minimal amount of change in the frequency like less than .5 kHz per shift. When I am hunting for really small targets that are less than 0.5 grams all the way down to 0.05 grams, yeah I might put M2 on its highest (13) frequency shift setting.
Adjusting recovery speed a bit lower to get more depth on coin sized targets or to avoid higher EMI levels makes sense if the site isn't too trashy. Adjusting the recovery speed a bit higher to handle more mineralized ground or higher target density sites makes good sense as long as you don't raise it too high so that the Legend can't get a good look at a possible good target and it's audio is too abbreviated.
If you hunt in areas where great targets are in the first 6" or so of the ground, your ground is not very mineralized and it isn't too trashy, well you are hunting in conditions that I have never experienced.
All of the older targets where I detect start at 6" depth and go deeper from there and the ground here at best is moderately mineralized with magnetite which VLF detectors struggle with.
