In the mid 1970's, the profession of Land Surveying took a major change in direction with the introduction of the digital electronic transit. This new instrument eliminated the need to visually align registration marks and keep track of many attributes of angular measurements. Then in the early 1980's, this technology took its next step by offering direct two-way connection to small computerized data collectors which removed any need for pencil and paper making all recorded data more reliable and allowing a day's work to be downloaded directly to an office computer when returning to home base.

Although increasing production tenfold and removing many areas of potential errors, this new technology still had drawbacks. Namely a battery issue based on complete dependence on expensive battery packs which recharged slowly, had a short life and were not readily available. Although most manufactures of Land Survey instruments offered a variety of remote (emergency) battery packs, when needed, these batteries plugged into the same data port as the field data collector. Since Land Surveyors had become dependent on the computer connection for dependable operation, unplugging the computer in order to attach a battery was an unacceptable alternative, but one which we had to lived with.

In the early 1990's, my frustration over having a survey job almost completed when my battery "died" forced me to build my first battery adaptor. When the "on-board" batteries run out of power, the data collector could be unplugged, and the tiny DaySaver adaptor inserted. The DaySaver adaptor would accept both the computer cable and an inexpensive alkaline battery pack. This adaptor is now part of my tool kit so that, when needed, the survey can be easily finish even after my primary batteries have given up.

Over the next few years, the adaptors and the battery packs had been improved and word spread throughout the surveying community. Since that time we have built and sold over 300 DaySaver adaptors to other Land Surveyors. We now also offer other helpful items which includes special cabling for powering GPS equipment.

Although the tiny DaySaver adaptor was the item which started this business, use of the dry cell battery has truly changed the reliability of the system. Because of the dry cell battery's appetite for abuse, more and more Land Surveyors found themselves leaving their onboard batteries home all together in favor of taking along only the DaySaver dry cell battery. Gone were the thoughts of ensuring the battery was fully dead before recharging, the feeling of dismay learning the batteries had been left on the charger all weekend, or realizing that eighty shots on a full charge was forcing an expensive battery re-cell or replacement.

Land Surveyors using instruments ranging from SET-2s and T1000s all the way to TDA5005s and Elna 10's wouldn't leave the office without the DaySaver adaptor and dry cell battery. Level crews carved a place in the foam for the DaySaver adaptor. Front seat check sheets have the DaySaver prominently listed. Precision alignment surveyors keep DaySavers in their tool boxes.

Now, with more and more instruments containing on-board software, that need for reliable power is even more critical. As most of these instruments contain servos, power consumption is multiplied, as is the stress of leaving the office considering the odds of finishing the job with the current inventory of batteries.
The DaySaver battery, although it doesn't like extreme cold (-30°c), will function properly in most temperature ranges. Packed in its rip-stop padded case, the shoulder strap allows it to be slung over one's arm for that trek into the wilderness for a full days work. Is your on-board battery still good? Leave the DaySaver dry cell battery under the seat for that terrible day when it truly turns out to be your day saver also.
