Consideration was given to transporting the yak upside down on my vehicle which restricted how I was going to mount any fishfinder. A fixed base would soon get damaged during loading/unloading operation, however careful, it was just a matter of time. One thing was for certain, it was going to be mounted past my feet and that dictated that I was going to need a larger screen so viewing was easy and clear.
The screen can be used in various modes, split screen, large digits, zoom mode, sonar mode, etc.. though I tend to keep it nice and simple as shown below.
As well as depth, I have water temperature and battery voltage displayed at the bottom of the display. Being an EU specification model the unit can be switched between metric and imperial. The unit, as well as being detachable, is fitted to a modified RAM mount allowing the mount to fold down into the footwell during transportation/storage to prevent any possible damage.
The picture is clear, the backlight very effective. Occasionally some light misting of the screen can occur, though this clears fairly quickly. At a later date I purchased a separate GPS unit (see review) which has fulfilled my requirement. A good unit at a reasonable price.
