Same on my Time Ranger. Set a slew of notches, etc., turn it off, forgotten. As a result, I tend to just run in disc with no reject or just iron.
If you leave the Time Ranger turned on, lay it down with coil vertical for awhile as you dig, you'll find the automatic ground tracking has set itself to "air" so it's quicker to just recycle the power to get back to proper gb.
Fortunately, this hasn't seemed to be an issue with the T2, so I just left it on whle digging.
No or minimal disc is the best way to start at a new site, anyway, then bring in more disc and whatnot as you see it's needed. But at a favorite site where you know how you want to hunt, might be nice to be able to save the machine's state.
I mentioned a save option in an earlier post, but some things can use a little redundant repeating. Mybe not to have more menus, but to just remember the last state it was in.
To add it might only require battery or capacitor memory backup or perhaps the addition of some different type of memory. Once you add the feature, you may find batteries don't last quite as long, as it probably takes a little juice to store the custom settings.
It sounds simple, but without knowing a lot of tech info about the design, hard to say how easy it would be to add it.
I have a pair of CB handhelds that remember last channel used. We bought them, put in new batteries, then it was several weeks before we used them. All 8 AA's were run down, just remembering the last channel I'd never used!
The dual 9-volt powered Time Ranger has soft power switches that will run down the batteries in a few weeks or sooner. So I just disconnect them. Thus, even if it did save my settings, I'd clear them anyway, because I hate buying new batteries allatime!
So, sometimes, too much hi-tech is not always a good thing!
