Yes and yes...especially if you are wearing polarized sun glasses...even not wearing them and in the best of circumstances, its nearly impossible to read that screen for anybody other than Chuck Yeager, who is alleged to have 20/10 vision....so I'm saying your rig is 'normal' to the AtPro I have...
So what I do is this: set up the rig to a preferred program, like Pro zero, iron off, 3 clicks from full sens. all these are saved features, then, a guy starts up the machine, holds the disc button and counts to '10' which gives a fellow a disc of 40....if you want 35, you just click down 5 pips, and commence to swing away...I have never once ground balanced, or used the pinpoint button, about the only button I might fiddle with is the sens...generally dropping it in heavy trash, and running it back up to no more than 3 down from full...
Now as far as the batteries, yes, the thing seems to crap out in function once it gets down a few integers, so I guesstimate time and change them when they are down to one bar...generally after they fall off 2 bars...then I use those same batteries in an alternate mfg's rig, and get another 10+hrs of good clean hunting out of them!
Anyway, rainbow or not, that screen is too dang small and hard to read to be worth a durn, and dont try to run this rig effectively once the tank gets below half....still, its a gold grabbing son of a gun, a guy gets prob 15hrs on the batts, with iron off and never using PP button...other than these two issues, and a few others, like the camlocks getting clogged up with silt, and freezing the shaft forever in place...I really like this rig, and hunt by tones with it in the water/beach only, never once tried it for hunting a dirt field or anything, thats what my other rig is for...
If a fellow was a detector mfg and was contemplating on making a rig like this, one would think, "hey, I bet a lot of old guys will buy this, and use it in the water, and I bet they will all be half blind and wear polarized sunglasses, since thats what all folks wear when hunting around the water..so lets make a dinky complecated screen that washes out when they try to look at it, just to give them all something to whine about!".."And, lets throw in a non-linear gas tank gauge so the poor blind cheap dope walks a mile from his car only to get 5 mins of hunting time when he thinks he has a few hours left on those batteries!" If this was the idea, it succeeded on all counts!
