[Rhodes22-list] Actual boating question

[Lowe, Rob]

I've got a hand held Garwin Legend Extrex that I borrowed from work to
try out.  It tracks great, but the "map" that the track is traced on is
off.  It's shifted enough so that it shows me sailing on the land, not
the lake.  Anyone know if there is a calibration feature?  The manual
doesn't list one.  Anyone had a similar problem? - rob

I got good results by using a handheld GPS clipped into a base 
mount.  I placed this right next to my Hummingbird fishfinder on the 
starboard bulkhead.  Both units detach easily for storage (or in the 
case of the GPS, for use elsewhere).  See attached photos, one of the 
mounts and one with the electronics installed.

The transducer for the fishfinder is mounted on the end of a short 
length of PVC clamped to the transom.  I can adjust the depth of the 
transducer to get still water if it acts up.  But most of the time it 
seems to work just fine and I haven't had to adjust it.  FYI - this 
unit also provides water temp.

Mostly I use the GPS for speed and time.  One screen display is a 
large-digit version with just the essentials on it and that's where I 
usually set it.  I can read that from anywhere in the cockpit.  The 
fishfinder has a large version of the depth reading that is overlayed 
in the corner of the sonar graphic as it paints across.  Again, this 
is easily readable from anywhere in the cockpit.

Cheers!
