I used my unit on the weekend for only the second or third time and the first since I updated the software. I was fishing in 60m and set the upper and lower limits on the unit. The display that it returned wasn't right, instead of only showing my selected range, it showed the full range from 0-60m with the range above the upper limit as a blank. So instead of getting the bottom 15 metres filling the screen I get 2/3 of the screen blank and the bottom 1/3 with the signal. I had to use zoom to fill the screen. This is not the way it should be. I have phoned Lowrance and the tech, who admitted that he hadn't used this function, wasn't aware of the problem. He is going to check it out and get back to me, but I was wondering has anyone else encountered this problem with their HDS unit?
This isn't a Lowrance bashing exercise, just looking to get a unit that seems to do everything else to do all the things the way it should. I love the bottom lock on the HDS, something that Furono have had for years, and am able to split into 3 screens to get the best out of these units. I have a full range, a display of 10-15m and a bottom lock, could probably split into a 4th if I wanted but that is overkill.
