Overview
Maven RFZ.1 is a laser rangefinder with a 6x to 12x optical zoom, letting it double as a monocular, and a stated ranging capability from 5 to 4500 yards with both line-of-sight and angle-compensated readings.
Most rangefinders use a fixed magnification; Maven's variable zoom is the feature the company points to as distinguishing this unit, since it lets the device serve as a monocular as well as a rangefinder. Two ranging modes, Field for isolating small targets against a busy background and Forest for ranging through brush or foliage, plus an obstruction filter, are built to handle different hunting environments.
- 6-12x21 variable zoom rangefinder and monocular
- 5-4500 yard ranging with angle compensation
- Field/Forest Function and obstruction filter
- Includes wrist strap, CR2 battery and storage bag
Who it's for
Archery and rifle hunters who range across both open field and timber, and who would value a rangefinder that doubles as a monocular, are the target buyer; those who only need basic fixed-magnification ranging will not need the extra zoom.
Pros and cons
- Variable 6-12x zoom doubles as a monocular
- Field and Forest ranging modes for different terrain
- Both line-of-sight and angle-compensated distance readings
- Ranges from 5 to 4500 yards
- No stated dimensions or weight in the listing data
Performance notes
The Field and Forest modes change how the rangefinder processes returned signals: Field Mode is built to ignore larger background objects and lock onto a smaller target, while Forest Mode is built to read through brush, trees or weather. Angle-compensated readings adjust the line-of-sight distance for incline or decline, which matters for archery and steep terrain shots where gravity affects the true point of impact.
