About six weeks ago I was replacing a Garmin 450 and they convinced me to buy the inreach SE Plus. I have just found out that I can't use this for geocaching or with g sak.    Does anyone have a need for this type of device? It has not been used at all in the last six weeks and I can't return it but I do have the manuals and the connection cables it's in perfect condition. I will give you 25% off Amazon price, which actually is $285 which for you would be $215. Thank you for any serious considerations
