Looks like an excellent detector. Lightweight, clean looking screen with a nice layout of buttons and menu system.
But, like you said, waiting on smaller coil(s). Just seems like all the detectors coming out have large stock coils like they like to use overseas. Then make you buy the accessory smaller coils adding extra cost to the purchase. Leaving you with a large coil that you and many others may never have use for. Worthless to resell, as no one will want it, unless you give it away.

Due to my aging wrist and elbow, always looking for the lightweight land based detector that balances properly. Will be keeping an eye on the Apex.
