Does anyone know where to send a Brunton echo 440 for repair. It has a lifetime warranty but eats up batteries in under two hours

Send it to the address on the warranty document or receipt you were given when you purchased it.

They offer a lifetime warranty. You can register here. www.dakotaquartzllc.com/warranty

If you're looking for the warranty I recommend you either consult with your local car dealer or try the site below. http://drivesmartwarranty.com/

Here is the contact info for Brunton, including warranty information: https://www.brunton.com/pages/contact-us

Use high power batteries with at least 2000mAh.

Hold the back button down until it changes (meters to yards or vice versa). Momentarily push the back button to step through the modes (rain, reflectice, >150, no text=<150). To use turn on with front button, aquire target and hold down front button for 3 seconds

Doubtful they will repair a broken front lens. It;s a LIMITED lifetime warranty.

you probably tried this but switch the battery around

Most GPS problems - Hangs, frozen screens, problems acquiring satellites, ETC, can be attributed to the device not having the latest firmware installed.
This firmware enables it to communicate with the satellites - but if they aren't speaking the same language they get confused easily. For Garmin GPS Automotive units, Garmin has you do the following before sending it in for repairs:
1 - SOFT RESET
2 - HARD RESET (CLICK HERE to see instructions for either reset)
3 - UPDATE the device using their WebUpdater software (CLICK HERE for that) Garmin is the only company that offers repairs AFTER the warranty has expired. They offer a FLAT RATE REPAIR service for units no longer in warranty. For Other GPS units please consult your owner's manual or their support site - as each model - and even manufacture dates - can lead to different reset procedures. TomTom
NAVIGON
MAGELLAN NEXTAR does NOT offer any types of Firmware or map upgrades or repair services. Instead - they have an exchange program to update to a new UNIT for around the same price as a repair would be. CLICK HERE for more on that. WARRANTY on most GPS devices is 1 year from the date of purchase. Broken screens are considered ABUSE - and not covered under warranty. Finally - If your unit is on the charger for HOURS, You've tried both the car AND USB type charger, and you turn it on... it stays on for a minute (or so) then powers down or never comes on at all - the battery has lost it's ability to hold a charge and must be replaced. Looking around YouTube - you can get a tutorial on how to CAREFULLY crack open just about any GPS. The tool(s) necessary typically are included with the battery purchase. Typically batteries run about $25 +/-. NiCd batteries are meant to be energized once a month so they keep active, and don't build up deposits that lead to their premature failure.
