A fish measurement device including a rigid bump board in combination with a slidably engageable assembly and a method for verification of fish measurement when using the device. The assembly design having the capability to mount the board to an underlying support surface as well as provide a user identifier for use in fishing tournaments.

A length selectable spirit level and measurement device for simultaneous measurement and leveling includes a first bar and a second bar. The first bar has a channel positioned therethrough, which extends between opposed ends thereof. A pair of slats positioned in the channel is slidably engaged to the first bar and thus selectively extensible therefrom. Respective indicia of a plurality of indicia coupled to the slats are alignable with a pair of points to measures a distance between the points. The second bar has a set of orifices positioned therethrough, each of which has a spirit bubble tube positioned therein and coupled to the second bar. The spirit bubble tube indicates an orientation of a longitudinal axis of the second bar relative to horizontal. The first bar is selectively engageable to the second bar so that the slats are selectively extensible in parallel with the longitudinal axis.

A device includes a ruler, a leveling device attached to the ruler and a plurality of pins. The device only requires one person to hang level pictures, paintings, frames and other wall hanging objects. The ruler is a made from a rigid material and has a plurality of holes therein where the pins are inserted. The ruler has a fixed length or has a telescopic structure. The plurality of holes formed in the ruler are spaced apart from one another and the spacing is uniform or variable spacing. The leveling device is a bubble leveler including three bubble levels where one bubble level is horizontally positioned, another bubble level is vertically positioned, and the third bubble level has an angle relative to the horizontally positioned bubble level. The plurality of pins include a threaded pointed screw with a knob attached to one end of the screw.

An adjustable measuring tool includes an elongated tool body and an extensible portion slidably positionable within the tool body and extensible through an open end. A thin tab extends downwardly from a front body face and has flat front and rear surfaces for alignment with edges of materials to be measured or marked. In embodiments, a backset gauge extends forwardly from the tool body, for measuring or marking backsets such as for grout or mortar. The extensible portion, tool body, or backset gauge may include measuring indicia. Another embodiment includes an adjustable angle attachment having two arms continuously rotatable about a central pivot point, for precisely measuring angles or squaring the tool to an angled surface.

An adjustable angle-measuring device comprises first and second linear arms, a marking member, an arcuate tracking member, a locking element, and at least two support channels. The first linear arm comprises first and second ends. The first end of the first linear arm is rigidly attached perpendicular to a first end of the second linear arm. The marking member is detachably attached to an intersecting surface of the first and second linear arms to form a pivot. The marking member moves along the arcuate tracking member to determine an angular measurement between the first linear arm and the marking member and the second linear arm and the marking member. The marking member comprises a locking element to lock the marking member to the arcuate tracking member. Each of the support channels are positioned at the second ends of the first and second linear arms to detachably attach extension members.
