There isn't really the need to have units in WA for testing, tho there has been units sold to folk over there and the feedback was exactly what we thought would happen on the typical goldfields from Kal to Leinster . Overload due to too higher gain, until lowered enough to achieve a GB. Lowering the gain on these models is not quite the same as other VLFs, these models still have usable gain to still find targets due to the way the gain setup works.
The GMT works well in most WA soil, however due to its gain and volume control being the same pot....lowering the gain meant lowering the volume...however it still works and thats the main thing even tho its running a high frequency. The FG+ and RACER Gold will have little problems due to having more control. Especially the RACER gold as its gain setup has much more refinement/resolution due to the higher frequency employed.
These units are being refined more in the Disc department for better abilities rather than the usual AM mode....while the AM mode still gives you a visual target ID, its the Disc side of things where the magic is wanted. Ya gotta face facts....the gold doesnt grow back, so you need to target the locations your VLF will shine....and there are plenty of locations for this to take place.
At the end of the day, these are VLF detectors, and are not meant to be compared with PIs. So some grace needs to be added when thinking your going to outperform a PI machine....its not going to happen. Target the trashy locations where PIs fail due to the amount of trash and you will be surprised.
If i can do it using a GMT, MXT, V3i in WA.....im sure there wont be a problem with these newer refinement VLFs in WA.
