5.6.6.2 Current Mode Display
The current Bottom Sampling Mode is shown in the main GUI window, in the lower right,
information area. If operating in equidistant mode and conditions, such as heavy roll, force the
system into the equiangular mode, the BSM indicator will be highlighted in yellow to indicate that
equidistant mode is temporarily suspended and the system is operating in equiangular mode. When
conditions change, the operation will go back to equidistant mode automatically.
Figure 66: Indication of Bottom Sampling Mode
The BSM designations:
• ea1 = Equiangular normal
• ea2 = Equiangular dual
• ea4 = Equiangular quad
• ed1 = Equidistant normal
• ed2 = Equidistant dual
• ed4 = Equidistant quad

5.6.7 Ultra High Density (UHD™)
Introduced in 2017, the Ultra High Density mode is an entirely new
technology developed by R2Sonic to provide the highest possible density of
soundings in one ping: up to 1024 soundings per ping. As opposed to producing pseudo beams by
interpolating data to create the appearance of double the beams; R2Sonic searches across each
beam footprint for additional soundings, using the extra-fine angular resolution that results from
R2Sonic’s advanced signal processing to precisely locate each point. This provides much higher
