Razor-sharp display, both from the sides as well as in sunlight. The sides and measurement histories are grottenschlecht represented and remain far behind the expectations. Thus, in the graphical representation of the depth profile, all indications for the evaluation of the measured values on both axes are missing. The current measured value is not marked if it is not valid (eg by flashing). The resolution of the display is fine and would yield considerably more detail information and allow, for example, several gradient graphs on one side. The motor data are well prepared, one can see what is possible. \ R \ nConcerning cable package is extensive but not practical. The depth sounder measures depths from 0.5-0.6m and has a just acceptable update rate , Disadvantage is the low track cable length of 6m, after which a backbone should come. If you have to extend with a backbone cable, a few parts are missing in the cable pack. Conclusion: As a display device for an echo so much too expensive, simply display the measured values can also be a cheaper S / W display device. However, updates may improve in the future, but they can only be made via a multi-function dislime. \ R \ n
