## Abstract

A fish length measuring apparatus that incorporates a digital scale allows fishermen to both measure and weigh their catch without touching or handling the fish. The apparatus incorporates a housing with a lip grip to grasp the mouth of the fish. A viewable digital output screen is connected to a weight-sensing member whereby the weight of the fish generates a digital numeric display. A distance-measuring sensor projects a beam towards a surface adjacent the tail of the fish and detects the reflection from that surface, then calculates the distance (i.e., length) and displays the length on the output screen. The contour of the housing facilitates hand-holding of the apparatus, and a variety of unique digital data may be selectively displayed on the output screen.

## Claims

### Claim 1

A fish measuring apparatus comprising:
a housing having a fish-clasping assembly to grasp a fish;
a digital output screen mounted on said housing;
a weight-sensing member connected to said fish-clasping assembly and said digital output screen to display the weight of the fish on said digital output screen; and
a distance-measuring sensor mounted on said housing on an extendable assembly which allows the user to direct a measurement beam around larger fish which would otherwise block said measurement beam, and connected to said digital output screen, said distance-measuring sensor calibrated to measure the distance from said fish-clasping assembly to a surface, wherein said fish-clasping assembly may be attached to a fish's mouth, and the fish held vertical with the fish's tail touching the surface, so that the weight and length of the fish can be displayed on said digital output screen.

### Claim 2

A fish measuring apparatus comprising:
a housing having a fish-clasping assembly to grasp a fish;
a digital output screen mounted on said housing;
a weight-sensing member connected to said fish-clasping assembly and said digital output screen to display the weight of the fish on said digital output screen; and
a distance-measuring sensor comprising an ultrasonic transducer mounted on said housing and connected to said digital output screen, said distance-measuring sensor calibrated to measure the distance from said fish-clasping assembly to a surface, wherein said fish-clasping assembly may be attached to a fish's mouth, and the fish held vertical with the fish's tail touching the surface, so that the weight and length of the fish can be displayed on said digital output screen.

### Claim 3 (depends on 2)

The fish measuring apparatus of claim 2 wherein said weight-sensing member comprises a digital scale.

### Claim 4 (depends on 2)

The fish measuring apparatus of claim 2 wherein said fish-clasping assembly comprises a lip grip.

### Claim 5 (depends on 2)

The fish measuring apparatus of claim 2 wherein said distance-measuring sensor is mounted on an extendable assembly which allows the user to direct a measurement beam around larger fish which would otherwise block said measurement beam.

### Claim 6 (depends on 1)

The fish measuring apparatus of claim 1 wherein said fish-clasping assembly comprises a lip grip.

### Claim 7 (depends on 1)

The fish measuring apparatus of claim 1 wherein said distance-measuring sensor comprises an ultrasonic transducer.

### Claim 8 (depends on 1)

The fish measuring apparatus of claim 1 wherein said weight-sensing member comprises a digital scale.
