I bought a pair of Steiner Observer glasses with compass. Think they are called Observer but they are on the boat so wasn't able to confirm. Anyhow, they are externally identical to the Commanders except the compass housing isn't rubber protected, and waterproof. Supposedly waterproof and damn close to the Commander for less money. Got mine from a closeout outfit for around $300. Like the ergonomics of the Steiner's. The short fore and aft length are easier to use for long periods of time than the longer conventional glasses.
