Portable GPS - Garmin or Bendix King
I have the av8tor and find it just fine to use and understand . The screen is a good size and it does exactly what it says it will do . I bought it as it was at about 40% of its usual price off a uk website .
But if I hadn't spent the money and coul do it again I'd save a little bit more and get the sky demon package . It is a fantastic tool which is very easy to use . A friend I fly with has one and it really is one of the best setups iv seen .
Try get a look at all there is to offer before u commit to a buy so you don't end up settling for second best like me. Havin said all that , it's down to personal choice !
