Good points - I too am a little underwhelmed, but as far as small coils are concerned, I really like the Deus elliptical coil. The width makes for great confined space swinging while retaining the depth and coverage of the round coil in a slightly lighter package (basically, why DD elliptical coils are so great). I think it has even better separation in some cases (if you run it at its highest frequency which at close to 80 kuz is almost 2 times higher than the Equinox max frequency of 40khz) than the 6" Equinox coil, but need to sit down and see Calabash's head to head tests to come to my own conclusion. Really wish ML comes out with a small elliptical for the Equinox. But I digress, this is about the Deus.
As far as the new software is concerned 5.X does not bring a lot to the table for the users of the HF coil and the legacy LF coils. One thing it does bring is the ability to adjust more user parameters if you are just using the headphones and not the control box. This is geared more towards the Deus lite users and the European users who typically only use the remote for programming the coils. They don't look at TIDs and are just basically digging all non-ferrous targets. They have very little non-ferrous trash in the farm fields of the UK, that if it rings up as something other than ferrous, they dig. So since they leave the remote in the car or whatever, having the ability to adjust more of the user settings like iron volume, audio response, reactivity, and frequency offset are helpful to the UK hunters and Deus lite users. The wireless pinpointer has been notoriously fickle on connectivity with the coil and so 5.X fixes that even more than what was done in version 4.1.
The main thing with version 5.X is the new hardware - namely the new LF coils which will replace the legacy LF coils which will be phased out of production by this fall. The new X35 LF coils have some great features including addition of a higher frequency (27.7 khz max) and a lower low frequency of 3.8 khz with 3 other base frequencies in between. No longer will frequency shift result in locking of Tx power at 3 so this allows a lot of frequency adjustment without TX power penalty. This is especially welcome news for the 4 KHZ low frequency band. Now this coil can be used for deep silver penetration in highly mineralized soils since you can now back off on Tx power which does not work well at high settings in mineralized soil. In addition, XP has added TX power BOOST at these lower frequencies which may further increase silver detection depth in mild soils vs. what can be achieved today with the legacy LF coils. So if you are a deep silver seeker the new coils may be a great addition. If I could have just 2 XP coils - I would probably choose the 9.5" elliptical HF and the 11" round X35. If I could pick one more coil, it would be the 9" round HF.
Was really hoping for something to help in wet salt sand, I do not see these new offerings bringing anything to the table there, so I am sticking with the Equinox at the beach.
