Tilt decides what depth you are looking at. The tilt lesson explains the geometry; this one is the controls.
At a glance
- Tilt range: -5 to 60 degrees, in 1 degree steps
- For surface fish, 4 to 5 degrees
- Auto tilt steps 1 to 5 degrees
- Auto tilt is off during target lock
About 8 minutes. Part of Run the CSH-10.
Setting tilt
Tilt is the angle of the beam's center below the sea surface. On the CSH-10 it runs from -5 to 60 degrees in 1 degree steps. Less tilt looks farther out and shallower; more tilt looks closer in and deeper.
Where is your beam?
Side view of the CSH-10's 6° transmit beam. Move the sliders and watch where the beam goes, where it meets the bottom, and whether the fish is in it.
Surface fish
For fish near the surface the manual suggests a tilt between 4 and 5 degrees. Use the beam explorer below to see why: at low tilt the beam skims the top of the water column, and the seabed only appears as a ring far from the boat.
Auto tilt
Auto tilt moves the beam up and down for you. The tilt step can be set from 1 to 5 degrees and the TX count (pings at each step) from 1 to 5. Auto tilt is disabled while target lock is active.
Reading the cursor
Put the cursor on an echo and the screen reports its horizontal range, vertical range, straight-line range, depth and bearing at the tilt you are using. This is the fastest way to tell what depth a mark is at.
