I Have a nuvi 200 . got 100 find with it . but had to do lot of looking for the cache . the handheld is alot more in getting closer to the cache. I found micro . just took alot of looking for them from 10 ft away when my nuvi told me to turn . try it and see . but there is some hard ones out there to find and a handheld come in nice to find them . I going to use both when I am out . that way they will tell me when to turn and what road I need . then out I will use the other
