MY concern would be whether or not the optics would support the longer
distance. After all the trouble, you might have just a piece of landfill.

A Bosch device capable of that 150 feet is about US$60 these days, or
less. And a cheaper off-brand device may be had for less than US$30.

Its optics I'm playing around at the moment with this 17GBP 50m (150ft)
not poking around inside yet.
Just in the process of boring/grinding a hole through a 150mm glass 3
dioptre magnifying glass to try passing the the transmit beam thru the
centre and then larger capture area for the focussed received, to see
how that works at 50m initially, ie how much darker a "reflector" would
be the new minimum .


So far , so good. 5mm hole ground in the centre and simply holding unit
in line with the hole, can produce a 5m reading without forcing errors
from its operational window , across the room.
Now to mount in a rigid tube , to try outdoors, over 50m span.
