HDS 2nd Review
Lowrance announces that there will be some type of side
viewing available as an add-on to the HDS models available in 2009. This all
the information they provided. This is something I will use and I almost
purchased a Humminbird last year because I like to look for “spots” and I could
see the value. Warren Parsons has provided me with many side scan images for
review and I believe I will put this technology to good use. I plan on using
the Lowrance side viewing and producing a DVD on interpreting side viewing. I
will compare the pictures with actual Aqua-Vu underwater film.
DrDepth BT Edition
The DrDepth program that I use to create 2D and 3D maps and
create maps for my Lowrance that look like LakeMaster and Navionics maps will
now can create bottom hardness maps. There is fee to upgrade from DrDepth to
the DrDepth BT Edition.
BT stands for bottom type. You can pick many different
colors for the hardness maps like most sonar’s allow different choices in
colors for the sonar. I prefer to use yellow for the hardest bottom and blue
for the softest which are the same colors Lowrance uses in their default colors
for sonar. Lowrance uses yellow for the strongest echo return which will be the
same on the DrDepth hardness map. I have 2 examples below showing a point that
has hard bottom extending past the actual point. I predict I will find many
good uses of this feature next fishing season. Pay attention to the waypoint on
the maps below.
