Watching and learning from other beach hunters

This week I spent a lot of time at the beach and I saw a lot of people using metal detectors, not surprising as the hobby is now very popular.
One of those days on a Treasure Coast beach I saw three different pairs of beach hunting buddies trying their luck for Spanish treasure, without being mean luck was probably their best chance of finding anything that day. 
All six people were using large search coils in the 14-15 inch size range and swinging their metal detectors like they were using a scythe to cut grass.  
I know from experience many of those search coils are heavy and swinging them like golf clubs must have been hard work.
Another old timer was using a heavy pulse induction metal detector with a large search coil tilted up at the front, I see this guy at that site quite often and he always has the front of the search coil tilted probably five inches higher than the back of the search coil.
I would say he is probably struggling to carry that heavy metal detector, also the lower shaft attaches to the back of the heavy search coil so its a bad choice of equipment anyway. 
In my opinion, search control control is a very important part of metal detecting.
Just keeping your search coil level and low during the sweeping motion will increase the amount of good stuff you will find.
You get near maximum target depth no matter what size search coil being used and you are actually covering the ground not swatting flies!
An extra large search coil tilted five inches higher at the front on a badly balanced metal detector is no help even if you dig it all. 
I always say for every inch above the sand or soil your search coil is swept, its an inch less in the ground you are detecting good targets.
Basics my friends, why swing a large heavy search coil and only detect targets directly in front of you which you are not probably going to detect because your already a yard ahead. 
Large search coils need to be swept low and level throughout the sweep.
All the pros of using large search coils are negated when you do not have good search coil control skills.
