Hi Herman,

I'm sorry that you are experiencing difficulties with your reTrace Deluxe. I have a few suggestions that may help improve its battery performance. One thing you can do is set the unit to automatically turn off in intervals of 5, 15, 30, and 60 minutes. Setting this to a low number like 5 minutes will help with battery life. Also, if the backlight remains on, this will draw heavily on the battery. You can change the settings for this feature as well. If you haven't already, please go to, click on the Support tab, and download the complete manual. Instructions are found in the "Settings" section.

There is a chance that your unit has a defect and that this is causing the battery to drain. If after changing the settings you are having the same problems, contact technical support:

We back this product with a 2 year warranty, so we'll be happy to replace the unit if it's defective.

I have the ReTrace Deluxe. It looks like the only software that will work with it is Their own program. You can download it from the Celestron site. I have Windows 7 and had to run in Compatibility Mode to get it to work. The buttons across the top of page (load POI, Save POI, etc...) are blacked out but STILL WORK if you know where to click on the screen. I ran the program first and it would not connect to my ReTrace Deluxe. I then noted where the buttons on the screen are that I needed. I ran in compatibility mode and the program works if you know where to press on the screen to load tracks, etc.... you may use marker to mark your screen when you first run the program to help later...

It is nice for point to point travel (ie: on my sailboat) but has a serious lack of battery life. It is also limiting because you can only manage way points on the computer. I only payed $25 for it (used) so I really cant complain.

24 hours after putting in new varta batteries into the new retrace deluxe they were totally empty, although I only did the settings of time, meter and celsius degree and tried (five or six times) to get a satellite signal.(It was +2°Celsius, so not too cold for the batteries!) The acquiring time always was longer than 5 minutes, later in the car it was not able to get any signal, and when at least I got the coordinates of my place, they soon faded away again. Now, maybe because of changing batteries, my settings are gone.
Got no answer when e-mailing on the support internet page of celestron.
No possibility of software download for MAC-users!!!
No use for real outdoor activities with that operation duration and problems of receiving. My rating: 0 Stars

Great item but. When using breadcrumb trail mode, if you run out of battery power or shut off gps you can't save the trail.
