having trouble with coordinates

[+jo2174]

I am new to geocaching. every time I try to put in coordinates, the last 3 digits aren't what I put in. Am I doing something wrong or is my GPS on the wrong format? the formats in my gps are

 

h ddd* mm ss.s"

h ddd* mm.mmmm'

h ddd.ddddd*

british national grid

 

What should it be set for

[+Airmapper]

h ddd* mm.mmmm' is the one to go for. You'll only need to go 3 places past the decimal, use a zero for the 4th. As in h ddd* mm.mmm.

 

What GPS is it? If it is a common brand someone here can probably tell you step by step how to plug in your coords.

Can you clarify that last part I highlighted....

 

Do you mean that you never have the chance to put them in - or that when you view the coordinates later it no longer matches what you put in??

Also, what type of GPS are you using. Most let you connect to a PC and download coordinates, rather than typing them in.
