My 1236x2 is so light that chest mount is kind of moot..
Nonetheless I keep several fisher coils mounted on different shafts for quick change,so is easier to chestmount the control box than rewinding cable around shaft whenever I change coils.and I,m sure also prolongs the cable life.
Tesoro and Fisher lowers are interchangeable.
13 pennies fit tightly between mounting ears on the fisher coils(My caliper is broken) makes a crude gauge.,
Oh Whites is not interchangeable with either fisher or tesor
lder white Eagle, DI,Etc will interchange with Spectrum except that the mounting hole on older units is smaller,so will interchange with newer Whites lowers but not Vise Versa.. I would like to know about Garret lowers,Ive recently seen several treasure aces go for as little as 50$, cheaper than buying a replacement Rod for Fisher.Maybe someone with different brands can try,.
Sorry for off topic but Then Be patient with Me,I have just bought used CZ5,and injured My back Before even taking it out of box .so feeling pretty useless otherwise
Happy Hunting,Mont
