just got my Terrova i-pilot mounted, haven't had a chance to put it to use yet, looks like another week. but while reading about recording trails, it says 3 trails, trail A, trail B, and trail C. my question is after recording 3 trails on say Dale Hollow lake, and the next time I go fishing and go to lake Douglas. if I record 3 trails on Douglas, does it erase the 3 that was on from Dale Hollow. so when I go back to Dale, the 3 trails are gone, or can I still use them. hope I worded this question so you guys know what I'm trying to ask. like will the record a trail keep 3 trails from each lake I fish, or lose them each time I record 3 more.
