Conclusion: Bought a pair of Cobra CXT545's for a Canadian wilderness fishing trip on a 86K acre lake. They worked beautifully . Excellent range, clarity and durability Could not be more pleased. The features and options make these radios an excellent value.
Summary: These were purchased as a replacement for an 8 year old Cobra system of Walkies, they have always worked well though with a somewhat limited range. They have a powerful receiver and this often works against them due to many people on the same channels.
