Rx 1000 wont power up even with new battery

This problem is caused by the 'step' inside the battery cover which prohibits the tip of the battery from contacting the nipple inside the cover. I fitted a thin piece of aluminium strip (20thou) and the rangefinder works perfectly now. Make sure you dont bridge-out the +ve to the neutral (i.e. battery casing).

Measurement is off approx. 4' to 5'. Any way to re-calibrate to have accurate measurements?

I didn't find the Prostaff laser 440 rangefinder on the website for, but I did find the 550 model. The specs follow:
  • Measurement Range 11-550 yds
  • Increment Reading 0.5/1 yds
  • Magnification 6x
  • Angular Field of View (Real)
  • Angular Field of View (Apparent) 34.9°
  • Viewfinder Display meters/yards
  • Eye Relief 18mm
  • Diopter Adjustment +/-4°
  • Power Source 1 CR2 Lithium Battery
  • Size (Length x Width x Height) 5.1 x 1.5 x 2.7 in
  • Weight w/o Batteries 6.3 oz
  • Objective Diameter 21mm
  • Exit Pupil 3.5mm
  • Supplied Accessories CR2 lithium battery.
I did not read that there is a recalibration for the unit, although a consumer might expect that. Has it ever been dropped to your knowledge?

The above link has contact information for service of the unit via telephone numbers.

The LCD screen will not come on when I depress the power button. The unit worked fine when I used it several days ago. It has not been dropped or jarred.

I would take the rangefinder battery and have the voltage checked. If you don't have a meter....radioshack will test it. It should be 3 volts a little more or less(2.9 to 3.2) if its good. Also make sure its in correctly. Positive end goes in the unit first. (flat side of the battery up towards you when you put the battery cap on) Make sure that little spring on the battery cap is there. Sometimes I pull that spring out....just a little to make sure its putting enough pressure to make a good contact. If you purchase a new battery and the rangefinder eats it up in a few days...You have a battery drain problem...This should be covered under warranty.

good luck to you!!

Nikon ProStaff Laser 440 not working

Here is the address to send your rangefinder for repairs.
  • Nikon INC.
  • 841 Apollo St. Suite 100.
  • Elsegundo, CA 90245-4721
  • Attention: Repair Department
  • Phone (800) 645-6678.
I had the same issue with my Nikon Laser 800 rangefinder. I sent it in and they wanted $311.00 to fix it so I bought a new one for $300.00 off EBAY. Today I was missing around with my old rangefinder and noticed after I put the battery in I could hear something loose in the rangefinder. There is a little metal tang in the bottom where the battery goes that holds tension on the battery that was bent down. I bent it back up about 3/16" and put the battery back in, now it works fine.

Do not know how to operate

First, be sure and focus the eyepiece on what you desire to measure distance to. Begin the measurement with the range dial set to minimum. Slowly tury the dial until the grey-blue image and the yellow image overlap each other. Read the measurement. If you suspect it is in error, you can calibrate the 400 or 1000 or 1200 by turning the screw slot within the range dial using an object you know the distance to. If the two images are off in the vertical direction, there's a screw below the range finder to adjust that. Turn it very little. Regarding the model 610, mostly the same except to calibrate it, merely spread the adjustment knob apart (spring loaded) and turn the part of it nearest your eyes so the yardage matches the distance.
