Has anyone ever used this brand of rangefinder?
 

The Sportsman's Guide has a Wildgame Innovations Halo 600 yard laser rangefinder in there catalog for 99.97.It says it's waterproof,fogproof and scan mode.6x magnification power.
Would this work for archery?It's 100 dollars cheaper than Bushnell or Nikon.
If it could range out to 40yds for archery and 300yds for gun it would be ideal.Thanks for any help.
