I supply and fit all major brands of electronics, including Lowrance.
All brands have their "for" and "against", all brands have their supporters and knockers, and all brands have units that will be returned for warranty repair.
Whilst I could have fitted my own boat with a number of different units, I chose Lowrance.
I firmly believe that the Lowrance HDS units are the best value for money units on the market.
The quality of the broadband sounder, the brightness of the screen in daylight, the ability to add all the extras like fuel flow, structure scan, radar, sonic hub stereo, and being able to network two or more screens is awesome.
They have the same abilities as the Furuno Navnet and the Raymarine E series at 1/4 of the price.
There are two things I have found that are slightly annoying with the HDS units.
1) The response rate from the buttons is sometimes a bit slow, however Version 4 software update has made it heaps better.
2) Calibrating the EP60 fuel flow meters can be painful, although they are quite accurate straight out of the box.
I have now fitted dozens of the HDS units for people.
We had a few returns with the first batch released - one screen came unbonded, one unit continued to freeze, one would not talk to the transducer, but apart from these few, I have not had to return an HDS unit in a long time.
Proceed with confidence, I have no doubt you will be suitably impressed.
Cheers
Pete
