For large or small a bench mounted one that measures 'height' above the
bench
might be handy.  Typically they are used on Precision ground Granite plates,
but to measure shells, a hard surface makes a 24 or 36" to the to three
decimal
places is nice.

Naturally the hand one is most flexible.   But one has to hold the shell
(or support it)
and then use (typically) two hands to measure.

Depends on need.
