With the (lets call it) Mark 1 you could use a larger battery pack that took two extra batteries so that rechargables could be used without loss of performance and to much battery life. This is not as important today as rechargable battery technology has improved so much.
The Mk 2 couldn't take the extra cells. Third parties in the U.S. and Europe offered performance sensitivity mods at very little cost that really did improve the machine.
Eventally Whites took it on board that people were having the mods done and did similar themselves. Unfortunately they took the route of having a gain control in preference to the pulse delay on the Pro model.
This is not a great drawback on a good beach but in bad ground/black sand having a pulse delay enables the machine to handle the conditions better and give improved performance over any detector that doesn't have the adjustment.
