this is the link directly to their website for extended warranty.
you get 1 year factory warranty but you can buy extended for another 2 years for less then $35.00.
So with 35.00 you get 3 years warranty.
It is up to you.
The rangefinder comes with a rechargable battery 9,5V(200mha) and a rechargable unit.
You will need a spare battery, because the lazer been is verry strong and used lots lots of voltage and your battery will NOT LAST FOR LONG. (on normal hunting situation you can go 3-4 days with one battery) or 3-4 continuing hours of lazering.
In the first day when I got the unit I was ranging everything and the normal 9.5V (150mha)last about 4 hour.
If you read the user guide the unit will STOP RANGING IF THE BATTERY IS BELLOW 7.0 V.
so you actually use just 2.5V and then the battery is garbage.
I know in this site are another 2 guys who got newcon 2000pro and another guy with a combo unit bino and lazer 3500.
It will be better if you can contact them and read their review also befor buying this unit.
Just to don't regret...
My self I bot this unit from Adorama (www.adorama.com
) and I got the unit in 2DAYS.
VERY FAST (the company is in states and I leave in Canada).
Here is my initial review
