When I'm standing in front on the tm would it be better to have a helix 2d/gps or di/gps? It would be nice if why could be explained some too.

DI imaging needs movement to create the picture like DI image ...
2d can be stationary and still usually interpreted by most Sonar users ...
So ...
*DI for searching and deciphering what's there ...
*2d for vertical fishing what you found ...
(Some use DI to tell what 2d is showing them) ...

OR you could buy a unit that has all three ... 2d sonar - Down Imaging - GPS :biggrin
