Jim,
My questions are: Am I gaining much, if anything in the depth department?
No. It's a dirty little secret of the metal detecting industry that (regardless of marketing ads) maximum VLF detection depth hasn't made any real improvement for 20 years now. It's just physics.
The improvements we're seeing today, have to do more with adjacent target separation...the ability to hunt in/through iron...TID at depth...better ergonomics...more efficient smaller coils...lower power requirements, etc.
Are both brands comparable in recovery speed?
A qualified "no".
Qualified because of your implied/real question, which is more properly stated "How does the CZ do in trash?".
The CZ is actually a very fast machine, but it tends to err on the side of 'dig me'...especially in damp iron trash.
So it can either null in iron or false more than the Tesoros...which (the Tesoros) are famous for spotting the goodies 'between' the iron with a minimum of nulling/falsing.
***Please note though; I tend to find more coins with the CZ's than with any other detector I've got...which is to say that recovery speed isn't everything.
(It does, however, depend on where/how you hunt...see below.)
Is there an edge one has over the other that I'm not considering?
The Tesoro is better for hunting in iron trash/nails...like perhaps a ghost town or an older torn/burnt down building.
Hunting for relics (or even coins) in a nail filled ghost town, and the Tejon will probably eat the CZ for lunch.
Hunting for coins in a relatively iron-trash-free park, and the CZ will probably eat the Tejon for lunch.
(It's not that the Tejon is bad, it's just that the way the CZ is set up for coin hunting is so incredibly efficient...Thank You, Dave Johnson)
In conclusion, both detectors are excellent examples of the art, but if you primarily hunt for coins in a park like setting, it's going to be really hard to find a unit better than your CZ..
