i have a dsp, starting its 6th year, I ride at bridger bowl and a lot of terrain requires a beacon so this beacon has seen heavy use 50+ days a year. The speaker came loose in the case which causes it to work intermittently. Liberty has offered to replace it for $150, seems fair for a brand new unit. Have not had luck contacting peips directly. I have a peips freeride for a loner when i ride with friends. This is a single antenna model and requires more user know how, not a good choice for a beginner. the range is also less then the dsp. This beacon only sees inbounds action where i feel beacon rules are in place to keep people from getting in over there head.
