5/26/09 I spoke with Bushnell technical support today and they informed me that this error "Er6" means the unit can not repaired. They said this is one of their oldest models and that they don't even have parts for it anymore. They did offer to have me send the old unit into their Returns department in Kansas, and in return for sending them the old/broken unit, they will send me an offer to buy one of their new units at a highly discounted rate. Not a bad trade I guess.

Bushnell pro1m not reading yardage. Showing e12?

Not a good unit. You have to return it as it can't be reset. You pay postage both ways even in the 2 year warranty.

Here is an email I received about the Bushnell Pro 1M Slope with regards to the E12 error:

This product has been discontinued and any new range finders will be announce in the first quarter of 2014 on our web site . I hope this is of assistance.

Please do not reply to this message.

Bushnell quest er6

Here is what I could come up with:

There is no code list available, so check these things:

1) Low battery, replace if necessary
2) You are trying to measure an object that is too close, try a more diatant object
3) You are not holding the rangefinder steady and have not gotten a reading off the target. Try an easier, larger, more reflective target as a check.
4) You have an electrical problem requiring repair.

If you are still getting an error, contact Bushnell at 1-800-221-9035 for instructions.

Finder comes up er6

ER6 means the unit has lost it's programming. Bushnell doesn't repair these anymore. Go to and find a unit that you like. Call 800.423.3537 and they will offer you 30-40% off on a new one for your old one.

Good Luck!!!!

Erorr 6

Er6 is the unit has circuit board failure. This seems to happen to old units> 7-10 years< If it is this old, Bushnell won't have parts anymore. They will offer you 30 to 40% off on a new unit with state of the art technology. Go to and pick out something you like and call them.


Good Luck !!!!

1 Answer

No yardage displayed

The rangefinder is out of alignment. Vibration, dropping these units make small mirrors inside move slightly. Over time the receiver cannot see what the transmitter puts out. Bushnell can fix, 4-5 weeks w/o unit.

Error code er6

Take the nice cover and neck strap off rangefinder to use on another item. Next use the rangefinder for hammer. boat anchor, etc. Seriously though the problem occurs often in the Bushnell rangefinders and it cost more to fix than to replace with a better brand. A $179.00 original cost rangefinder cost $10.00 to ship back to Bushnell and another $235.00 for repair of a non specified problem for a grand total of $245.00. I consider this a rip off from Bushnell.
