I am slowly becoming enamored of this CIII SL, with the 5.3 "Black Max" coil. It just swings so naturally in the hand. Of course there is no real ground coverage, but working it in tight around trash and park equipment oughta be a breeze.
Since that will be the first task I put it to, it seems natural that it ought to be tested on something worth finding under such conditions - and I aint talking pulltabs! So, I used my favorite item: My wedding band!
Being that it's 14K gold, it has the low end conductivity of an average square tab/nickle, which is to say, not so good. Silver is easy, but nickles, etc... well that's a bit more challenging.
I tested the CIII/BlackMax against all my other detectors on this ring for response. Each instrument was set up similarly, thus:
SENS: 3/4 of full
MODE: Jewelry or equivalent DISC setting
GB(if available): slightly positive
This was a straight test and no "super tuning" or any other extras were employed. All instruments hit hard with the coil close to the target, but in terms of response as I raised the coil from the target, here's how my MrB-CIII fared against >>>
My trusty Garrett 1350, stock coil - Garrett got about an inch more depth. Fast swing speed improves response.
My trusty Garrett Ace 250, stock coil - Ditto for the little Ace 250.
Tesoro Golden uMax, stock coil - Equal to the MrB-CIII.
Tesoro Vaquero 5.75" coil - Equal to the 1350. Fast swing speed improves reponse. In fact, going too slow caused the response to disappear altogether - so much for the much hyped "slow Vaquero swing"! (I suggest that the Vaq should really be considered a moderate swing machine.)
Tesoro Tiger Shark - Barely equal to the CIII.
This is not definitive by any means, but it gives some idea of the capability of the MrB-CIII as far as depth response is concerned. Since I really want to use the MrB-CIII/Black Max Combo as a park-yard "cherry picker", I'll do a bit more speed and target masking/separation testing next time around.
