Each detector has its own strengths and weakness. Knowing how and what it is telling you and your interpretations and how each adjustment effects the results are more important than which detector. The environment is of great consideration, black sand, electrical interference, area to swing a certain sized coil in, etc. may be overcome by one detector over another by design without user interface. Physical aspects such as weight, wireless headphones, angle of grip, control of operating parameters can each help in improving a signal the operator can more easily process if it is a desired target worth retrieving.
I own over 20 detectors and each was obtained for a specific purpose and as such has become my favorite "go-to" detector in a specific situation. Features that have proven to be high on my list of desirable list are: what is the desired target, physical comfort when in use, wireless headphones, notch discrimination, turn-on and go coil size, Multi-frequency and PI.
All that being said the Excalibur and the Equinox 800 are in my car ready for a trip to the beach. I may take a PI detector also especially if I think the environment may warrant it.
