Q. wouldn't the Whites Dual Surf Pro PI be a better detector for the Treasure Coast?
A. I don't know.
I've used the BHID300 on many beaches, including those with black sand, and never had any problem.
I will be using the Whites Beachhunter on the treasure coast later this week and will report back.
Q. Do you find the Excal II iron mask feature valuable on the beach?
A. The iron mask is very useful, but the excal has a slow recovery after masking out iron. If there is a coin or something near the iron, you may not get a signal.
Often, the iron masks kills the threshhold tone, and the tones doesn't come back. I'd have to touch the detector to the metal scoop to get the threshhold tone to return.
Q. Does the Excal II multi-frequency allow you to find more targets than the BHID300 with dual frequency?
A. My experience has been I find more with the BHID300. With the Excal, I tend to get more falsing and interference from cell phones, towers, electrical lines around fishing piers, and other unknowns.
But it may be that I swing the larger coil on the BHID300 slower because of its heft, and the slow swing on any detector will usually produce more targets.
Q. Do targets emit different frequencies depending on their composition?
A. On the excal II, every target produces a different tone. With a lot of practice you can learn to tell from the tone what the target might be.
But for me, with over a year of experience with the Excalibur, the only tones I knew for sure where those from a beer can or those from a coin.
Q. What is the value of having more frequencies above dual for the beach?
A. You'd probably need to check the Excal website for that answer. I don't know.
Again, the excal II is a great machine. I have found many things with it.
Right now, I prefer the simplicity and depth of the Whites BHID300.
But I'm not going to sell my excal ii, because there may be instances where I'll prefer it over the BHID300.
