of course it was the very first unit... a portable...
but you could mark a fish 30 yards out from the boat
off to a side... cast to that direction and hook up
like you were sight fishing.... so i've been dying to buy
another one... it was like being able to spot a trash can
and casting to it.... very exciting fishing !!
