bushnell guns

I was wondering what differences are between the 1900 & 1911. Bushnells websight only talks about the 1911

The Bushnell model numbers 1900 and 1911 have the same basic design specification. All the models perform essentially the same. The difference is internal -- different (IC's) integrated circuits (usually lower power consumption, sometimes smaller), cheaper circuit boards (no loss of performance) etc. Internal parts between models are not always interchangeable.
